This thread is for all of the members that purchase and install the JBP TriFlow Cams. Post up your pics, videos and dyno sheets if ya got em'!

I'll start by merging my posts about it from the GB Thread:

Whelp, picked my car up tonight, this is a pretty sweet setup. The idle is slightly deeper, but not extremely noticeable. Except for the occasional moment where the idle gets a little rough and bounces between 600-1100RPM until it can stabilize itself back out...BTW, it looks like in the high RPM's, boost does drop. In second tonight, I was hitting 15.5 pounds fast as hell and then after 5500 or so RPM's they dropped down to 12.5. Weird, but the car definately didn't stop pulling. Power feels strong. Unfortunately, I didn't have much time to really play around with it and see how the boost hits in each gear.

I didn't really have a chance to get decent video of the exhaust note at idle because it was freaking cold as hell out here, but I got a few short videos of the car in second and third gear on the highway. There's definitely a slight increase in mechanical sound from the engine. I'm pretty happy with the way this turned out. It pulls pretty nicely on top end, but we won't really know what kind of power I'm making until I get on the dyno the 24th. I couldn't tell much about the acceleration because the weather was so cold. But in high gears it seemed to pull pretty well. The dealership kept their word about install price, so it turned out to be $330 something after taxes. They gave me a free wash and all. The funniest thing is that there's a small whine when I'm not in boost. Like when I'm driving around the city in high gears at low speads. It's pretty cool. I can't wait to get this thing dyno'ed.

I guess, without further adue...

Sorry about the shakey camera, my g/f couldn't keep herself steady in the seat with me on and off the throttle so much.

shit sounds insane!!!! i want them too!!

:lol: Got the PM, so it looks like it worked.

shit sounds insane!!!!

x2! I just realized that you don't have an exhaust and are still getting a nice deep sound out of them!

yeah he does hes got a 3" full exhaust

His sig. says that the exhaust is currently is his future "plans".

(I hope I'm reading his sig. right :lol:)

Wow, lol, sorry SS super but you be wrong! I have stock exhaust from the manifold back.

To take a quote from one of my favorite movies, "Maybe we should have a spelling contest."

Take some stand still rev clips!

wow that sounds fucking nice. stock exhaust is so deep sounding

im guessing you went toying around before we got blasted with snow lol

It's all good. I'm just bustin' chops anyways.

My girl and I went into the cold to get you a clip of the standstill revs from the engine bay. It's too shitty out to pull it out of the garage to get a clip from the back. If you listen to the last 10 seconds of the video you can hear it bouncing between 600-1100RPM's...

Hearing how deep it sounds on your car is really making me even more anxious to hear how it will sound with the full exhaust. I still can't get over how nice it sounds.

Here is the video I promised and pics of some of the snow by the garage out back...

EDIT: The screwed up link now works haha.

Try again problem fixed..lol

gotta love that cam idle, now we want exhaust cam idle video haha

yea stu, ha um if you look at the pics i posted in the V-day thread it's gonna be about a week before I can do that...

That really sounds nice, the idle note is real nice.

yea stu, ha um if you look at the pics i posted in the V-day thread it's gonna be about a week before I can do that...

i know man i just want to hear it!

Can't wait to get some numbers

I had that problem to, the cams actually build more boost, and what is happening is the the Boost by bass valve is kicking in and bleading all your gained boost.

cheack out my dyno: you'll see two pulls completly stock, and one with just cams

http://img1.putfile.com/thumb/1/3019072964.jpg (http://www.putfile.com/pic.php?img=4653835)

what's happening is that the by-pass is programed to blead anything past 15psi,

you'll have to do one of three things.

-get GM stage 2 or 3
-get HPtuner tune your car to change the by-pass limit
-boost by-pass mod

the second one is obviously your best option, you'll get way more out of the cams that way.

but if your stock do the by-pass mod and you'll see much better gains and the car will drive even better.

unfortuneatly i didn't think of the by-pass mod when I did that last year.

OMG I WANT!!! (is all i could come up with when I heard it)

Hmmm, that idle sounds a bit odd, but it isn't damaging. I like it. Tri-flow cams FTW!!!!!!

player_1, I do have GMS2. But, regardless, I am having it tuned by TTP on the 24th with 60's, 2.79", and NGK BKR7E's. That's why I'm so excited for the dyno tune! Should see some good numbers.

I would really like to see a scan log with these, as well as dyno gains. Cams are supposed to "open up flow" through the engine. Any other supercharged car I've modded, the car would LOSE boost when adding a cam, allowing you to drop a pulley size and gain more power. I DO NOT like the idea of these cams ADDING boost, because that tells me there's a restriction. Hopefully someone can prove me wrong, but I'd like to see more info from people who've installed these.

Why not drop down to a 2.5"? With the increased flow the boost would be in the 18-19 PSI range I would think.

Was the install price of 330$ just for the cams?

Matty, I'm perfectly fine with the 2.79. I don't want to overspin the blower. Regardless, we'll find out how things work on the 24th.

Shortbus, the $330 was for cams and valvesprings at a discounted price because the dealership screwed up and quoted me low and took too long on the install. I was supposed to have the car this past Friday, and didn't get it until Tuesday at 5:30pm...

Bad06SS, I didn't get increased boost, boost built faster to my peak of 15.5psi with GMS2 and dropped in the higher RPM's to 12.5

In no way did the vehicle feel like it slowed down when that boost dropped. It felt just as strong, if not stronger, than before the cams...

so those valve springs are going to allow you to run a higher redline right.

so those valve springs are going to allow you to run a higher redline right.

Yes, not sure what JBP rated them at though.

Edubs, I have to wait one more day until I can get my car and get the dyno results, its killing me, especially after seeing and hearing how your car turned out.

I think they're rated up to 7800RPM, but I'm not going to push it with the stock valvetrain and balance shafts. I think I'm going to have Matt at TTP tune for a 7500RPM redline, but shift at 7000-7200 at the most. Maybe I'll get crazy from time to time, but I don't want to risk it since GM says the stock balance shafts shouldn't go past 7K...

yeah this is making me want them. But then again. I must wait for the TC or SC swap to be complete. How long did it take to install?

A professional install on cams and valve springs should be just shy of 7 hours the way my dealership did it...

That's awesome EDUB. Car sounds DAMN mean, and this gives me a pretty good idea of what mine will sound like. I have stock exhaust also. I am gettin more and more excited about getting the cams and all.

A professional install on cams and valve springs should be just shy of 7 hours the way my dealership did it...

Iam going to go to my dealership and see how much they qoute me.

I'm glad you got the JBP Springs, installed, but DOn't tune to high of an RPM

with that Cam and vavle Spring or OK and don't have to worry about valve float up to around 7K RPM, but it's risky to go higher.

if you want to higher get the Ferrea Springs. Do Not Get Bates Springs what so ever I Broke 4 springs and bent 1 valve.
I has lucky that the valve seized in the guid and didn't touch the piston.

Ferrea is they way to go for who ever is thinking of boosting there Rev limiter.

if your not then stock is fine.

What's wrong with going past 7K with the JBP springs? Mev has stated before that they're fine as long as you don't go past 7800. Obviously, the balance shafts are not gonna hold up that high, but the valvetrain with JBP springs and stock balance shafts should be just fine at 7200...

I am currently at 7200 with the stock valve springs. I won't be exceeding 7400 redline with the JBP ones. I don't plan on shifting past 7200 with the 7400 redline either.

Thanks for the input Dan. Sorry to hear about the hold up w/ the car. Hope everything goes well for you tomorrow. Definately let me know as soon as you find out more info!

could you give us a soundclip of the exaust at idle???just want to hear how simular ours sounds.thanks

Will do!

Yeah, Mike, it's gonna be a little while before I can get my car outta my garage and start it up. Sucks too cause my cams and the tool I have to send back are in the trunk. Just can't get to them right now...

Why, you ask?

The alley where my garage is...
http://cobaltss.net/gallery/files/6/9/9/8/IMG_1969.jpg

My garage... (the one on the right)
http://cobaltss.net/gallery/files/6/9/9/8/IMG_1964.jpg

I'll take a sound clip of the exaust inside the garage.LOL

Damn That Sounds Amazing!!!

:lol: Thats just a little bit of snow you got there! LOL You may need a bigger shovel :lol:

Yeah, I can't even get to my car from the other garage either. It's split and I only have access from the front, which basically means I won't be able to get in there until someone plows me out.

Dan, I didn't even bother with the shovel, I gave up and just went inside to stay warm...

I don't blame you, I would do the same thing if I woke up and saw that mound of snow there. The roads are starting to dry out here, just a little bit though. Should be dry enough to have some fun when I do get the car back.

:twothumbs for a stedy idle sound clip also i want to hear it!!!!!!!!

Sounds good. Is it really that lopey like in that video or is it acutally seraching for idle?

I cant wait to get mine back from gridning! I have full exhaust so it should be fun + hptuners and dyno time will then be comming in spring to see what this little 4 banger puts out.

Someone dyno SOON. Everyone is dying to see the results.

Kyle

I'm hoping to dyno tomorrow! I also have a full exhaust so curious to hear the sound as well.

DAMN THIS SNOW!!! I have the loot on the way from my taxes to pay for install, and dyno tune. I'm set, just need...what was it that I needed...oh yes, CAMS AND VALVE SPRINGS....lol

DAMN THIS SNOW!!! I have the loot on the way from my taxes to pay for install, and dyno tune. I'm set, just need...what was it that I needed...oh yes, CAMS AND VALVE SPRINGS....lol

:lol: I hear you man. After seeing and hearing Edubs, its making me jealous and more impatient to get my car back.

I can imagine..Hell, I'm impatient waiting to even get my cams, let alone have everything installed. lol

I'm impatient waiting for someone to plow in front of my garage so I can get to my car and ship everything out. Maybe I'll even get a video of the exhaust for you, but the car isn't coming out of the garage until the 24th at the earliest...

Only reason I never got a clip of the exhaust was the echo the garage will have.

Dude you're lazy, get your butt out there an shovel that garage out..LOL!!! I want my cams..

Lazy my ass, I've spent the last two days driving around Albany helping friends did their cars out of the snow and helping push cars that got stuck! I actually lost five pounds from when I left to when I got back Wednesday. Must have been all water weight. I'll see what the status is when I get home from work today. Maybe that's a project for tomorrow, dig myself out...

P.S. - That shovel in the picture of my garage is 5 feet long and sitting a foot and a half off of where the pavement is. Just so you can figure out the scale of things.

It's all good man, just f-in with ya. I'm just excited about getting the cams and everything, not to mention gettin em all installed. Just ordered my injectors, they should be here wed. Then all I need is my income tax to come in and for the cams. No pressure..lol

I know you're just playing. I'll do my best for ya! I just can't wait for the weather to clear up so I can get some real footage!

Me too...You're gonna have the same basic setup as me. lol..I have my 60's on the way, already have the 2.79 installed and exhaust will be next after this install. Damn, I miss exhaust. Still not sure if I should go with 2.5" or 3"...

I'm in the same spot as you...

3" may be too big for a 2.79 w/ 60's, but with the cams, it might be just right. I think the dyno with the CAI, Cams, 60's and 2.79 will really tell us a lot about where the power needs to be gained and how exhaust flow should be opened up. I've heard the big restriction with our exhaust is actually the ports on the head, not necessarily the exhaust itself. So a nice free flowing header with decent sized collectors going into a free flowing 2.5" exhaust might actually be sufficient for our setup. Only time will tell. It all depends what you want to do down the road anyways. If you ever want to go turbo, don't waste your money. If you're going to stick with a blower, you can go nuts on having a nice custom setup made...

Very true..Are you going to be dynoing without exhaust?? If not, what size are you gonna have on there?? Yeah I hear that the DP is one of the best places to start as far as piping sizes go. I'm talking to a company that maybe working on a Stage2 head for our cars. Hopefully I will have some info in a couple weeks on that.

I will be dynoing with the stock exhaust. It's going to be a while before I have my custom exhaust made by RD Fabs...

Lemme know how you make out on the upgraded head.

I will man..It's a work in progress still. Have to email dude for some updates.

The funniest thing is that there's a small whine when I'm not in boost. Like when I'm driving around the city in high gears at low speads. It's pretty cool.

I don't like the sound of that. GM warns you multiple times about removing the cams. Everything i ever saw about that states that if the correct tool is not used when removing them to hold tension on the timing chain that it will bind on the water pump when reinstalled and cause a constant whine. That kinda sounds like what you are getting. Just a thought.

It's not a constant whine, first of all. Second, the cams were installed by a GM Technician at a GMPP Dealership with the GM Cam Tool, which you are correct in saying that it holds the timing chain while the cams are being removed...

Regardless, I'll look into it. Thanks for the thought.

I noticed you said the cams increase boost, this fact alone has made me decide NOT to get those cams. Cams should if anything DECREASE boost due to better air flow, if they increase boost then that means they are letting less air flow.

He did not say that it increased boost, these cams WILL decrease boost. He actually mentioned that in the other thread also.

Reading>You

My god, why doesn't anyone read what I write in threads. I have GM Stage 2. I got 15.5lbs of boost before and I get that after until higher RPM's where boost actually decreases. Sorry to come across as an ass, but this seems to be a trend lately where no one really pays attention to what is said in posts. I don't want people going around saying that "Edubs said he had increased boost with the JBP Cams." Like I've told everyone else, the only way we'll find out if these cams really do anything will be when I get dyno tuned on this coming Saturday. Please make sure that you are not going around telling everyone that these cams are no good before you have any proof!

So.....what your saying is....these cams suck? :lol: JK. Have you had the chance yet to get out and drive a little or is the weather still crappy?

I noticed you said the cams increase boost, this fact alone has made me decide NOT to get those cams. Cams should if anything DECREASE boost due to better air flow, if they increase boost then that means they are letting less air flow.

not necessarily true.

it is all dependant on valve overlap, and weather it favors intake cam or exhaust cam.
in the case of these cams, because they're designed for a supercharger.
the intake cam is still open when the exhaust cam is closed and and the piston begins the compression stroke.

this can only be done with a forced induction car because a NA car cannot feed air at the required pressure to overcome the pistons compression stroke.

this increased time that the intake cam is open allows for more air to be ramed in to the cylinder. hence the increase in boost. = more power
if you put a cam like this on an NA car, and it's an effective way to lose power.
put it on a car with a supercharger a see th power climb.

Edubs your cams are making more boost, but after your tune you'll see that. this is good.

for anyone who still doesn't beleive me, look and that Damn dyno chart I posted earlier in this thread of my car.

you can see that the first 2800RPM I actually lost power, that because I was not creating enough boost to overcome the piston, but after that it just kept accelerating.
unfortunatly I had stock tune so for me I hit the set boost limit, and the by-pass blead all my boost back to 12.5psi:thumbsdow
but once I've finished getting tuned:guns: whatch out for me.

So.....what your saying is....these cams suck? :lol: JK. Have you had the chance yet to get out and drive a little or is the weather still crappy?

My car is still trapped in that damn garage. I have to wait until the weather melts it over the next three days to be able to get in. I am not a happy camper, because I should already have sent those cams and the tool back. I want the rest of my money back damn it...

Player_1, I may be making boost sooner, but I did not notice boost actually going any higher than it had before I installed these cams. Maybe it has something to do with me having the GMS2 tune and you had the stock one?

thats not what you said was happening.
your first post said that asfter 15.5 psi your boost dropped down to from 15.5 psi to 12.5psi.

that's exactly what happened to me you can see the drop on my dyno where it happens.
that tells me the the by-pass kicked in and blead your boost

I have the General Motors Performance Parts Stage Two Performance Package installed in my car!!!

I hit 15.5psi before I had the cams installed. It went all the way to redline before. Now, in high RPM's it drops to 12.5psi...

*Cough, Cough* Were you able to get to the dyno on the 24th, im eager to see these results. I also ordered the cams but im waiting for the next batch to be made.

Results!

He had his car towed to the dealer. Something happened with timing and shit got broken.

I went to gas up Friday evening before the trip Saturday, but the car wouldn't start after I filled up. Both Mev from JBP and Matt from TTP think that the cam position sensor wasn't correctly calibrated or the timing was off. Only way we'll be able to find out is when the dealer gets off their ass and checks my car. It was towed on Friday evening and they said they were "backed up from the weather," so they couldn't look at it until tomorrow at the earliest. Trust me, I'm more anxious than anyone else. I will fill everyone in as soon as I know what the hell is going on.

Edubs, I think tomorrow may be the day for me as well. And believe me, I'm just as anxious as you are to get my car back.

did anyone install the jbps in a 2.2L yet?????

sounds good man also glad to see someone in north east NY lol

You have a PM sir...

ever find out what happened? did dillhole and weedus screw up the timing????

We'll find out soon. The dealership thinks they can start looking at it tomorrow...

Interesting, sure sounds great in the vids! What's the dealerships take on the aftermarket cams? Or do they even know at this point? lol.

how many times did you try to start it?? My cam sensor was installed wrong for two days, and sometimes the car would start on the first try and other times it took up to 6 tries. Just wondering.

Tofu, they know that they're aftermarket cams. I told them that if they installed them correctly, it would run just fine. They're trying to weasel out of it, but in the end...it'll end up being that cam sensor.

Joe, I tried probably half a dozen times and didn't want to try anymore. The car was starting to backfire because I was dumping so much fuel in there. I have a good feeling that it's the same situation as you, I just didn't get lucky with it starting this time around. It had all the symptoms of the cam sensor being installed wrong. Sometimes it would first try, sometimes it wouldn't. Let's just hope I flooded the sucker and that's why it never fired up...

Yeah, for future refrence, the cam sensor drive has no marks on it. You have to mark it when taking it out, or you will not be able to get it to go back in the same place for sure the first time. There is a notch on the sensor, but nothing in the cam, so it is all guesswork if you have no marks. I was helping the tech replace the sensor and told him that I thought he was one tooth off. The car wouldn't start until the 4th try, and ran kinda funny. This was late on a friday night, so I took it anyway and drove it like that friday night and saturday. Finally sunday the weather cleared up, i took the sensor out and turned it one tooth, car fired right up, check engine light went away, and car has run perfectly ever since.

Thanks.

How hard is it to get access to the cam sensor and switch teeth. If I could have got my car started, I would have just done that...

All in all, I just hope the dealer is honest and fair w/ me. If I did something wrong, I'm cool with paying for it. But this just screams bad install all over it, and I hope he steps up to the plate and stands behind his work...

Its on the top of the head, over the tranny. You take off one bolt and it slides out, then just turn the sensor and pop it back in. takes like 2 minutes. You may have to try a few times to get the right one though, there are 6 sides. I knew right away, the car sounded different when it fired. And after 2 or 3 ingition cycles the CEL will turn off.

Whelp, we'll just have to see what the dealer comes back to me with. A fight, or an easy solution...

Well, here is most likely the last update for me this week. Matt was able to finish everything up with the install of the cams and everything else. He put the car on the dyno for a baseline run before he tuned it. And well, the car didn't make it through the run. The head gasket blew. I'm not overly shocked that it happened since I know that I will be in "unchartered" areas performance wise, but to have it happen know with everything else happening was awful news. I was eagerly looking forward to picking it up tonight, but that will obviously not be happening. The earliest would be this upcoming Monday or Tuesday as i will be getting the Cometic Headgasket to replace mine.

I will be shipping back my stock cams and the tools from JBP tomorrow so that I can get my refund and get things going for everyone else who is waiting on their cams.

My god man, I'm so sorry. Don't get discouraged though. Take the opportunity to have a positive outlook on things. Replace the headgasket with the Cometic and the head studs while your at it. If I were you, I'd replace the intake manifold gasket with the updated one too. You should be in great shape after that and you won't have to worry about daily driving it. I'm pulling for ya man, just keep your head up and realize that it will all be worth it when you get the car up and running.

I'm trying to hang in there man. This has been the "project" from hell though. I thought today was the day to get my car back and then BAM, blown headgasket. I'll be waiting atleast another week now. I am getting the Cometic headgasket, head studs? Maybe. Intake manifold gasket has been replaced by Matt already so thats good. I just can't take much more waiting and any more problems. I'll guess its back to the waiting game though. How are you making out with your car man?

The stock head studs can't be put back so you might as well put better ones in there instead of new stock spec ones. I really hope everything comes through for you. I can definately identify with having a the "project from hell."

The tech called and spoke with Mev today and it seems like the cam position sensor is the magic button. I called Mev and he's confident that it's the sensor. Hopefully the tech can button everything up tomorrow morning so I can pick it at some point. I have class the next two nites in a row, so I don't know when I can get there. The dealer doesn't know that I spoke with Mev, so we'll see how honest they are with me when I talk to them tomorrow.

Good luke bro! Im really interested in seeing the out come.

Thats awesome though that they don't know you talked to Mev as well. I hope everything works out for you too man, I may just port and polish the blower and get new tires while Matt has my car, but after hearing the price for replacing the hg, I dunno.

Whelp,

New updates for you all. Talked to the dealer this morning and they had fixed the cam shaft position sensor. Fired right up in the morning, but a little later had start up issues once again. Just got off the phone and they've been doing diagnostics all afternoon. They traced the starting issues, they think (oh god), to the theft module in the vehicle. It was a brief phone call because no one is really available to talk to me, so I told them to have the service manager call me when he gets out of his afternoon training session. I don't know what this means for me yet, but I do know that they ordered a new theft module to be over-nighted so that they can install it and see if that solves the issue. More updates when I find out more...

Good to hear that there making progress and narrowing down the problem.

Yeah, let's just hope they don't try and stick me with the bill for all of this...

With your troubles, Player1's problems and G5Mikes sputtering issues, it seems the JBP cams are a pain in the ass. Hopefully the theft module straightens your issues out.

Yea, they better not foot you with the bill.

I think it's more an issue of changing the cams in the LSJ being the "pain in the ass."

I don't think there would really be any "issues" if someone that knows the LSJ top to bottom performed the installation. We'll see, though...

With this car, if it's not one thing, it's another!

haha ^^^x2!

With your troubles, Player1's problems and G5Mikes sputtering issues, it seems the JBP cams are a pain in the ass. Hopefully the theft module straightens your issues out.

Another thing to consider guys,is to have your car tuned right away,my injectors are fucked,due to the fact that I did not tune the car right away,I have to wait a week for new ones,Camshaft positioning sensor is also very important,I know from experience:lol: and whats the issue with the theft module? when my cams were put in my theft modulale was causing the car not to start up and I had to have it towed to the dealer also

Well, I did not know that...

Mike, what did your dealership have to do to rectify the situation, and did you end up having to pay for the fix?

I planned on have the vehicle dyno tuned last Saturday, but this problem started and I had to have it towed and fixed before I could do the tune. I plan on taking it down to TTP the first available chance I have after getting it back, and I'm replacing the GMS2 injectors w/ 60's right before it goes on the dyno. Please let me know what happened w/ yours!

I wish I had known earlier that you had the same issue with no start after install. It would have made my situation and the diagnostics for the dealer a hell of a lot easier...

Well, I did not know that...

Mike, what did your dealership have to do to rectify the situation, and did you end up having to pay for the fix?

first off it came down to something simple,the shop crossed two wires leading from the MaF, and this caused a non startup,second was the camshaft position sensor,it has to be exact.I too am having to wait one week for new injectors,My tech only wants to put them on the day before the dyno tune so there is no chance of fouling them,he knows of the cams and also says that hpt is the keyfor this not happening to the injectors again

What about the theft module? What was the cause for that not letting the car start. Right now my dealership is ordering a new module because they think that is the problem. If connecting things back up incorrectly blew the module, then I need to let them know before they hook up another and blow it to smitherines...

Damn I wish I had my car here right now to show you a pick,but these two wires are identical and if put in one of the two identical spots causes this to happen

Do you know what the two wires run to and from? Their purpose?

I've got to call up the dealership and tell them that they're just going to blow up another theft module if they don't fix those wires...

post up a pick of the engine bay,I'll try to point out which two they areTRY is the word though your engine is different from mine..Ok here is a pick of someones 2.4 engine bay,by the TB there is a connector(has purple on it) there is another connector that feeds off the same line,Im almost sure these are the two connectors that got crossed

lol...

I don't know if I have a pic of the engine bay that has enough detail to spot those wires, lemme check...

Try this pick of my engine bay...

your engine bay is different from mine,but if you have an identical connector running off the same main wire and you disconnected them during cam installation than that would probly be them and try switching them,I can remeber but I thought one was exaust and the other intake

We'll see what happens tomorrow. They have just been informed that two identicle wires that might have been disconnected during the install could be crossed and that they should check their wiring again before plugging a new theft module in to see if that solves the issue...

cool,let me know what happens

Thanks a lot for the help, I'm definately updating this post as soon as I can...

They're installing the "theft module" right now. We'll see how they make out. This is pretty funny. They have had my car for a total of 10 business days. That doesn't include the two nights it was dropped off or the time I had the vehicle in between installation and failure...

I'm wishing you luck bro. I know what you are going through. My car was in the shop for almost three weeks when they had to order one of the coolant lines going to the oil cooler that was cut by the factory spring clamp. My parts guy called a Saab dealer in Mass. of something and they shipped it to us. Last one in the country, GM said it was not a real part #. I made sure he put regular clamps back on when it went together.

Service Manager and Tech are at lunch right now, have to call back in an hour. These guys are probably trying to figure out a way to blame this on me. Definately gearing up for a war here. It's funny how no one knows what's going on when those two aren't around...

heh, heh heh heh, heh...

Guess what? It's not done! The tech was in the last few minutes of downloading the appropriate flash to the theft module when the Time Warner Rep that was working on their internet connection unplugged the dealership's internet connection. What happens when you lose connection during a reflash of vehicle electronics? Precisely, the unit locks up and is useless. So, after trying to source one throughout a 180 mile radius with no results, they tried to call in and add it onto their order for the day. We'll see tomorrow if it shows up in their order. If they don't get it tomorrow, they prob won't have it done until Tuesday and I'm leaving for vacation for a week on Wednesday.

Good news is, I spoke w/ the service manager and he is covering the bill for the install issue and the module is covered under warranty. The only issue him and I need to work out is the towing of the vehicle. He's 40+ miles away from me and his service writer told me to use their tow company, which resides near them. So 40+ out to get the car 40+ back = $250. He's trying to get some warranty coverage on it, but we all know where that will get him. I told him that I'm willing to work with him a little when the time comes if he continues to shoot straight with me...

Glad to hear that there covering all their work though. So I guess this means no car until next week?

If I am lucky, tomorrow. If not, then hopefully Tuesday night...

Gotcha! Hope you get it tomorrow man.

Well...Tune Time has the install parts that I need, but I'm still waitin on the cams and springs to come in, not to mention that he is a bit backed up till the week of the 12th. Got my appt set to be in that week though so...We'll see

You bastard...j/k...

I won't be able to drive back down there until March 31. I guess now you'll have to let me know how things work out. Best of luck bro!

any updates?

My latest updates are...Called Geoff at Colt Cams Monday morning and he said mine were getting shipped out right after I get off the phone with him..lol He mentioned it taking from 7-10 days to get to me, that sounds long..I dunno..

Trust me Andy, coming through customs, that is just fine. It took mine about 5 days or so and mine were express shipped.

Toronto - The new theft module is supposed to arrive this morning. Let's see if they can flash and install it w/o any problems. If so, the car should be up and running tonight. Just in time too, I leave for vacation for a week tomorrow...

Keep us posted on how everything comes man.

Yeah, I hope it gets here within 7 or 8 days. I have the appt for the install and all, setup for next wed. to drop her off. That would put me at 8 days including this saturday. Gettin excited...

Yea, I received mine in 4 or 5 days as well when I placed my order. You should be good Andy. Hope everything works out for you Edubs.

lol, unit didn't come in yesterday. I'll be over in their neck of the woods today so I'm going to stop in. We'll see what excuses they give me when I'm right in front of them...

Bring a bat...

fuck the bat, bring a sledge hammer!!!!!!!!!!!!!!!!!!!!!!!

Sorry to hear man, I may be getting mine back tomorrow, if not then, Friday for sure.

Or saturday, maybe sunday..Hmmm how bout monday

You know the situation all too well Andy hahaha.

Holy shit just finished reading the thread. One thing after another good luck dude have fun on your trip and cant wait to see a exhaust vid and dyno results!!!!

Man what a pain in the ass for a cam upgrade. I hope it all works out for you. I think I'll just by another crate motor and build it from scratch. To much down time for me.

Any new news Edubs?

slow

Mornin bump for some updates for sure..How's it goin Meeester Edububble??

Hey everyone. I'm in Florida right now on vacation. Haven't talked to the dealership since Wednesday morning when they told me that it was running now but they're still throwing "theft" codes. They've been doing trouble shooting on the code w/ GM Tech Support but I haven't checked in on it since it's quite a while away. I prob won't be on again till I get back Tuesday night. It's been so long I just threw up my hands and hopped on a place, lol. Oh well, we'll have to see. Maybe I'll call for an update tonight...

May the god of torque be with your holy relic of speed, blessed be thy blower, Amen.

^^^HAHAHAHAHAHA

How can you be in a Florida at a time like this Edubs? hahahaha Hopefully you'll have your car waiting to be picked up when you get back man. Enjoy the rest of your trip you lucky bastard haha.

Guess who's car is in the wash bay as we speak!!!

I don't get out of work until 6-6:30 so they won't be there. They still think that I'm liable for the tow bill, but I'm waiting on a call from the service manager about that. They've had my car for a total of 21 working days since I first dropped it off to have the cams installed. The service writer tells me to have it towed by a particular company and I do what he says, and now they want me to pay $250. Bullshit! I've missed two appointments to have my car dyno tuned and they've had my car 25 actual days, that's practically enough to have them make a car payment. Especially seeing as I haven't asked for a rental car or anything else like that. Just that they right their wrong...

Whelp, update time, the service manager (Mark) at Eagle Chevy/Caddy is a stand up guy. Did exactly what I asked him to do, stand behind his work and fix the problems he caused. He got the tow bill covered and had the car all washed up for me to pick up tonight. I won't be out there until 7:00 or 7:30, but I get my car back tonight!!!

hell yeah man! now hurry up and get to the dyno! i want to see if these cams are going to be on my next mod list or not.

Good to hear Edubs!

That's good news Edub..

Yeah with the ZZP mount from Dan and my idle surge issue, mine kinda sounds like the cams are already done. lol...

Car runs great. I'm out of town again on personal shit but I'll be back into town Tuesday morning. Dyno is scheduled at TTP for 3/31. I just can't get down there an earlier. I'm just happy my car is back in my garage safe and sound...

See? Someone really IS listening to our prayers. =)

Good to hear everything is finally up and running!

Give us this day our daily WOT and lead us not into importation.

Finally got a little time to get that exhaust video you all have been begging for...

Sounds mean.

How much is the idle moving around? It sounds like its dropping pretty low. I would like a nice cam idle, but not like that.

DAMNIT!! I can't hear them at work...

Actually, on the road it stays pretty even and doesn't move around like that very often. This also doesn't take into account the fact that I don't have the car tuned yet either, which most likely would smooth idle out a bit...

did you need a tune with these cams? yeah right

Tune is highly reccommended, but not necessary. Basically, I'm just running rich as hell and the car is making adjustments constantly to adjust to the cams. A tune would have the car spot on knowing the cams are there and let it be able to adjust for other things instead...

Sorry, I'm a little off my rocker today...

I'm driving down to Tune Time Performance in Jersey. Matt there is a really cool guy. He helped me out a lot through all the issues I've had with these. He'll have a lot of experience tuning cars for these cams and installing them. If you don't want to drive down there, Ted Jeanetty @ Jeanetty Racing is a good guy in CT. They're both very well known and respected tuners. Jeanetty will be a bit more pricey, but I believe he has a better dyno setup. He hasn't had a chance to get a car w/ these cams on a dyno though...

now that drive to jersey for you must be at least 4 hours or 5 hours right?

3 1/2 - 4 depending on traffic and those damn muscle spasms that make my foot put the pedal to the floor...

I don't really speed that much, I'm a 12 over kinda guy. But, honestly, mapquest puts it at a little under 4 1/2 hours for me. Generally, I get there 20-25 minutes faster than mapquest going 7-12 over the speed limit. I'm confident I can do it in 4...

EDIT: Scratch that, mapquest gives me 4 hours, I just looked it up again. That would put me there easy in under 4...

I'm going March 31 to get this sucker tuned w/ the 60's

Here ya go!

2 HOURS!!! no way, it takes about 3 hours to get to albany for my mom so wouldnt that be like 5 hours for you?, oo right my mom was driving so maybe, but i can probably make it there in like an hour and a half or so.

Trust me, mapquest says 3hr 42min for me. I'll tell you for sure in a week and a few days...

When you come down, hit me up. I only live 10 minutes from TTP.

I think you have my number.

Yeah, I've got it, I'll give you a call when I get there Dan...

Yeah, I've got it, I'll give you a call when I get there Dan...

wait so your running your cams on no tune?

Correct. He is running on GM stage 2 tune.

I think you'll be all set and done with everything before me Edubs :(.

Correct. He is running on GM stage 2 tune.

true but you dont need an additional tune?

You don't have to get an "additional" tune, but it would be more beneficial in both performance and in the driveability of the car.

alright i going to have to save up a few thousand and get all the parts i want and tunes i need, and the most important mod, GOD DAM TIRES!!!!

Yeah, EDUBs should be done before me also. Still waitin on my cams for cryin out loud. lol..Ah well...Soon enough I guess

Yea but, Dan's car has been there for like 2 months at least now..haha!

Good point..lol..Poor guy. Haven't heard from him in a lil while, any news on the head?

Well the latest is that the rocker arms are getting replaced. If that doesn't work, the entire head gets pulled again.

Oh my, Dan, keep you chin up man. I'd hate to lose you after all of this. Just keep reminding yourself of what a beast this thing will be. I drove around town for hours last night and my car is running extremely well with the exception of how choppy everything is due to not being tuned. I can't wait to get down there next weekend.

My last stop last night was to fill up at the same gas station, at the same pump, that my car wouldn't start at last month. It was nerve racking, but I took pictures and the sucker fired up for me to drive it home...whewwwwwww

Damn, that really sucks Dan. I agree with EDUB though about how much of a beast she gonna be when fixed though. Matt won't let ya down, I'm sure she'll be just as reliable when she's done too.

Nice to hear EDUB. Can you feel a difference in performance with the cams? I can't wait man, mine should be here soon, bout a week or so..I hope. lol

Not huge right now because I think the car is pulling timing in high RPM's, especially in third gear. I think the 42lbs injectors are getting a workout. It should be much better when I get the 60's in and tuned...

I appreciate all the optimistic outlooks from everyone on here and from everyone at TTP. There have been points where I have actually thought about selling the car and all its parts, I actually got to the point of pricing out new cars (EVO, STI, SRT4, etc), but like you guys said, when all said and done, this thing will be a beast and should peak at or above 300 whp. Its just very frustrating at this point, but with the continued support of members here and from Matt I feel that I will be very pleased in the long run.

Ill laugh if I can pull you with only 244whp : )

And thats when I cry and sell my car haha. I let you know the day that I'm coming to pick it up if you want to meet up still.

Yea you better. It can be your first race! BTW i forget, are you still on stock clutch?

He sure is, all 40 some thousand miles yo. lol..I gots about 11 thousand 5 on mine. Lemme put my new K&N filter on, I think I'll have more ponies then you Dan, oh wait, I got some new stickers since the dyno too. lol..

Yea you better. It can be your first race! BTW i forget, are you still on stock clutch?

Sounds good! I'll have to learn how drive it again though hahaha. Yea I'm on stock clutch still (20,000 miles), but that will have to be changed soon too.

Latest update, rocker arms and lifters did not work either :(. Have I reached my boiling point? I think I may have, I'm coming up to the point where I don't think I care how much of a "beast" the car may turn out to be anymore. The hard work and effort that TTP is doing is much appreciated, but no matter how big or small the project, my Cobalt just doesn't respond well for some reason. Edubs do you have any further updates or new news on the possible problem? Is a part-out and/or a for sale sign coming soon... its possible.

Damn Dan, I'm sorry to hear about that man. They have any ideas what direction to go next? Has Matt called Chris to see if he has anymore ideas?

Damn EDUB...I would think from what Matt has said, that these cams should help her to run a bit richer. Hmmm...Guess we will find out next saturday. I wish ya some luck man. I'm getting to the point where if this doesn't work out for ya'll that I may try to get a refund because of fear that it maybe the cams. Keep us posted for sure guys. Hey Dan, if you need anything man, a ride somewhere or some shit, be sure to hit me up.

I am in the same situation as Dan, idle surges and stalling. No idea what's going on at this point, but I don't have the time or money to put into finding out what the problem is. My car is parked out back while I find a shop closer to me that has the "Know-how" to tear it apart and diagnose the issue. It's scary that the only four cars that I know of with these cams on the LSJ are not running. I have no way to drive it to a place to thave the CEL(s) read, but it definately has thrown one. I just pray to god that nothing is damaged inside my valve train or, god forbid, my block.

Anyone that knows anything, take a look and let me know your thoughts...

Engine Idle Issues (http://s174.photobucket.com/albums/w86/howark/?action=view&current=MVI_2605.flv)

I've decided now to give up on the JBP Cams. After seeing 4 people install them and have them fail, I am going to see if it is the cams or not. If it is, then it will solve a lot of headaches and problems. If its not, then... I don't know. I am going to put stock cams back in the car and see what happens. Or, does anyone know if the cams from GMPP fit our cars? They are listed as "applicable for the Ecotec 2.0L and 2.2L N/A and Turbo applications" according to crateenginedepot.com. If someone could please give me a definate answer to this ASAP it would be much appreciated. It could be the last effort that will help to persuade my decision as to what the future will bring for the Cobalt.

Has anyone had them tuned yet? My car used to surge at idle a little. Changed some things on my tune, and that went bye bye

Mine have been tuned for. I am seeing a cylinder #2 misfire since the install of the cams, so I'm going to try the stock ones and see what happens from there.

sounds good!!!

So are any of these ss sc cars working with the cams?

Let me know how you make out bro. My car is basically sitting out back until I see what happens with yours. I'm not fortunate enough to have someone as knowledgeable as Matt to look at my car right now. Best of luck. Somehow, I have a feeling that w/ stock cams in, the car will run just fine...

Not a problem Edubs, I'll let you know as soon as possible. A lot is going to depend on when I can get a set of stock cams, if there in stock, I can have them for Tuesday, if not then I don't know when yet. I think it is pretty obvious that there is an issue with the cams at this point, 4 people have them and all 4 people are having major issues.

So what your saying is jbp never tried these cams in a car and then sold them to all you guys. Boy I feel sorry for the guys who sent in there cams for regrind and now they will have to get new ones just so they can drive there cars again.

TRIFLOW® DESIGN-STAGE 2

The future of cams is here!! Our TriFlow camshafts are no mistake. They are the efforts of both ColtCams and JBP. Any manufacturer can provide you with a regrind: Crane, CompCams, Crower... its real easy to do. Only JBP can provide you with TriFlow®... This revolutionary technology, has been proven in our test cars to produce INSANE power, throughout the power band. Something that is not capable by conventional camshaft grinds, which tend to shift the powerband to the top-end of engine speed.


I wonder which car made INSANE power...

hmmm... Im assuming you guys have been in contact with Mev, what is he saying?

Well, I'm not going to bash on JBP at all until there can be proven information that the cams are the problem. Yes, it is very coincidental that their cams are 0/4 now with Cobalt owners, so yes it doesn't look good at the moment. Matt from Tune Time Performance has been in contact with them once, on Friday I believe. Mev or some other employee there suggested that the lifters may have been the problem. So that afternoon, Matt replaced the lifters and the rocker arms and there was no difference. Now we are waiting back for another response from JBP on Monday. Regardless, I am going back to stock cams to get a more definate answer on the issue. Obviously if the stock cams work out fine, then we would know that the issue is with the grind of the JBP cams.

So what your saying is jbp never tried these cams in a car and then sold them to all you guys. Boy I feel sorry for the guys who sent in there cams for regrind and now they will have to get new ones just so they can drive there cars again.

player_1 has had these cams in his car for over a year with no problems. Then again JBP did the install so there is someting else to look at, non ectoec experience techs installing the cams into the engines.

player one did have problems....

Is Ed's car running now? How many miles did he drive with the cams in?

I could care less what the issue is. I'm not on here to point fingers. I'm here to find out what the hell is wrong w/ my car. It ran perfectly fine before I put these cams in. Now it doesn't run. I just want my damn car back and running like it used to. I've got my hard earned money invested into this and I know DTM has a heck of a lot more invested. I would love for this to be something stupid and for the cams to be an amazing upgrade. I'm just starting to get curious why I don't see one person on this site w/ JBP Stage 2 TriFlow cams running well in this thread helping out.

I'm waiting to hear back from Mev. I called and PM'ed him and he called back and left me a message telling me to pull the valve cover off and inspect for damage. I called back trying to get more info but haven't had a chance to talk to him. What does a non experienced tech do wrong that Mev and his crew at JBP do different when replacing cams? I just need help here. Where's Player_1 so that he can give his opinion?

I dont think there are any...

Has anyone had them tuned yet? My car used to surge at idle a little. Changed some things on my tune, and that went bye bye

I was under the impression that HPT does not tune em in??????

I dont think there are any...

When I bring that up there always seems to be someone that says there is. I haven't talked to one yet.

In his message to me, Mev even said that it couldn't be the grind because they've put these cams in other's cars before. Whose? I need someone that knows what is going on to step up and help out w/ this...

Right now, the best shot I have is to wait and see if replacing these with stock cams in DTM's car gets his running again. Unfortunately, I'm kind of hoping that it is the issue, because that would at least be an answer for me and I would know how to get my car back up and running...

my rocker rollers and lifters will be replaced this week,hopefully a faulty lifter was my problem all along.

when player 1 attempted to get tuned and it was a disaster i posted my concerns and nobody gave a shit. There are numerous issues with cams, this is no secret, also tuning is absolutley nessesary, if no tuning was involved we would of never known his iat2 temps were the highest we have ever seen on an LSJ motor, im not bashing, im trying to give you some insight mainly because if i was my car i would be livid, take what i say as a grain of salt and if i were you id throw the stockers back in, peace.

IAT2 temps???

over 200* I believe

The stockers were sent back for me to receive a refund for the core charge that was processed when I bought the cams. These cams offer "Gauranteed Performance" according to the website. And I was told that no tuning was necessary, just strongly advised, which I planned to have done by Matt @ TTP next Saturday. We just need to figure out what happens when stock cams go into DTM's car this week. That could answer a lot of questions having the TriFlow cams out of the car for inspection...

Mine are supposed to be on the way, so...I hope it's something dumb causing this. Otherwise, JBP is going to owe ALOT of money to quite a few peeps. The only other thing that I had mentioned to DTM that I heard could be a possibility is..Maybe the setup that Colt Cams has for the re-grinding is off. If the cams are not ground down right for top dead center, that could be a reason for cylinder 2 to be misfiring. Just another idea, DTM is going to be bringing this up to Matt tom. to see what he thinks about it.

so we all seem to have the second cylinder misfire in common,well keep an eye on this in combination with possibly running rich this might cause your second injector to go like mine

Regardless of the outcomes -- thanks for being the original cams testers! When it all gets perfected (or not) then you'll have helped all Cobalt owners.

Where to start... well I think it is obvious now that player_1 has also had serious issues with his car as many of you know, I have also talked to with him to see his progress and him likewise, and well there is none thus far. To victory_red_SS, Matt from Tune Time Performance is doing the install of these cams on my car and is very knowledgable with the not only the Ecotecs, but just about any other engine out there haha, so I don't personally think that it has to do with un-intelligent mechanics in this situation. To g5mike, my lifters and rockers were replaced on Friday and did not fix the issue. Not trying to burst your bubble, but just pre-warning you so that you don't get dissapointed as I have far too many times over the past 2 months. Other parts that have been replaced and work that has been tested include: coil packs, spark plugs, gaskets, compression tests, head taken apart once, any other mechanical test that you can think of, and now stock cams. Also, my car was tuned using HPTuners to see if the tuning could help resolve the issue, and well it didn't. To distillion, I saw your warning about the cams and your opinion that they may not have been the best investment after seeing how they were with player_1's car. I took it into consideration, but I had also already purchased the cams at that point, so it was too late for me. I like to take everyone's opinions and ideas into thought before I do anything to my car because like everyone else, they want the car to run at peak performance without any issues. As Edubs said, I am trying to get a set of stock cams back into my car to see what results take place. I also sent mine back to JBP for the core refund, so I will be ordering another set now, hopefully they will be in stock. If not, then who knows when things will get done. If anyone has there stock cams that would be willing to let me borrow or buy, please let me know (just in case I can't get any soon). Like I said earlier, it is very odd that 4 people now have attempted to use these cams and all have the same problems, some worse than others. Is it coincidence? Who knows at this point? But it is very fishy, so hopefully I can get some answers to this ASAP. I will let everyone know how I make out with the switch back to stock, as I know that many people have shown interest in the cams and the few of us who bought them have invested a good amount of time and effort into them. You can't really understand how dissapointed, frustrated, annoyed, and upset I am with the current outcome. I have been without my car for 7 weeks now and have not been able to solve this problem. I was shooting to break 300 whp with the help of these cams and was looking to greatly decrease the amount of boost I was running while making more power. At this point, it seems that this will not happen with these cams, but until the stock ones go back in and prove me wrong, we won't know for sure. Sorry for the long post, just wanted to keep everyone up to date and informed.

WOW! these are some serious issues here,but to clarify I did run fine for two months and loved it.But I think runnin rich finally did in my injector causing me to dump three litres of oil,hence putting me where Iam at now.having said that Iam hoping when i get the car back Thursday she runs fine.The dealership still does not know where and how the oil got out,but since they are replacing the lifters they think the #2 lifter was faulty which probly explains what happened to the #2 injector

Well I hope everything works out for you man. Let us know if things are able to be fixed with just replacing the lifters if you wouldn't mind.

Here ya go Dan, this is the best I could find on that other cam question that no one answered. lol...If it turns out that it is the cams causing the issue, this maybe the direction that I go. Guess we'll see...Hope this helps a bit.

Thanks Andy, I read that as well. But I also read that it won't work with the stock cam sensor and vacuum pump or something. Regardless, I'll be going back to he stock cams at this point and calling it a day as long it works. If you get any more info on them, let me know.

I sure will man, you do the same. Please keep me posted on the stock cam deal, cause I have NO idea what I'm gonna do as of yet.

No problem, I should know this afternoon sometime how soon I'll be able to get a set of stock cams.

Just got off the phone with Mev regarding my car. He saw the video and we both agree that something mechanically is wrong in the car. I'll be heading out to Autozone to rent an OBD-II scan tool to see what codes I have thrown tomorrow night. Then, I'm going to take the valve cover off Saturday, since I'm not going to TTP, to inspect the valve train and take pics of the damage or lack thereof. From there, Mev and I are going to trouble shoot through this whole issue. Mev is confident that the cams are not the problem, convincingly so. He did admit that he would do whatever is needed to rectify the situation if he was at fault. He still feels that it is an issue due to improper install. After we find out what my valve train looks like, him and I are going to devise a plan of attack. Most likely, it will involve me going back to the dealership to have them rectify whatever issue was caused during an improper install including the aftermath. We'll see what happens Saturday...

Glad to see that your getting somewhere there Erik. Keep us posted.

Thanks, I'll be up tomorrow night or Wednesday sometime to let everyone know what codes I threw and Saturday I'll post up the pictures of what I find. I'll see what Mev has to say about them and see if I can get him to post his comments in this thread if he has the time...

I also sent him an e-mail on my situation.

Since these are lobe heel regrinds, why hasn't anyone mentioned the possibility of lifter collapse or over extension? That would be my first concern. I'm sure Colt or JBP would know how much additional lash the lifter is able to take up before failure if they are selling regrinds. I wonder what that number is and how close these regrinds come to that.

Mev and I spoke about what possible issues there could be with the manufacturing and grinding of the cams. He mentioned three things. Let's see if I can remember...

#1 - Material Grade/Hardness
#2 - Centerline
#3 - Material defects/damaged cams

He mentioned that Geoff at Colt tests all three aspects of the cams before they ship out. I was concerned about this also. I am currently trying to touch base with those that ordered their cams ground off of Steel Billet Cores. Those sets of cams should have the stock centerline and not be adjusted due to the regrind on stock cams. I have yet to find out if any of those people have received their billets and installed them. We will see what we find out in the upcoming week. I have quite a few PM's out there waiting for response. Like I said before, I don't want to point fingers until I have proof of what the real causes are for my vehicle not running...

'06 Arrival Blue LSJ

I'm curious. Are you running that setup currently? Who did you have grind the custom cams? Did you dyno your setup?

damn yall still having problems with these cams....return them back to jbp and keep stock....STOCK CAMS FOR LIFE...thats my new motto..but either way i hope yall get the cars running soon...esp. you dan

I ordered new cams, so if and when I get them, I'll let you know. JBP called me about a week ago asking if I wanted steel, or the GM cores.

So what did you pick? GM Cores or Steel Billet?

I'm curious. Are you running that setup currently? Who did you have grind the custom cams? Did you dyno your setup?
Same person that made riceeater's cams on the redline forums. I'm still waiting on parts to finish the build so I'll update when its done. They are base circle regrinds but the lash adjusters are shimmed to maintain the stock height. Riceeater has a video over there of the same cam I bought but with a 280 grind.damn yall still having problems with these cams....return them back to jbp and keep stock....STOCK CAMS FOR LIFE...thats my new motto..but either way i hope yall get the cars running soon...esp. you dan

Stock cams will only flow a limited amount of air. Limited air = limited horsepower.

Also interested in your outcome, Witt. It seems like with each passing day, there is more and more info that gets passed along with what the problem may be, just no answers unfortuantly. Oh and Steve, thanks for the "esp. you dan" hahahaha, you just want someone to cruise with again lol.

What I'm interested in seeing is the results of the cars with the steel billets. I'm pretty sure I know the lash adjuster's maximum travel and also stock height, but I can't find the source where I originally learned it so I won't quote it until I can find a credible source. I really think shims are going to ultimately be the answer imho but this is a guess since I haven't actually seen these cams in person, I'm just going by what I can remember of the maximum amount of lash the stock valve train can take up and what JBP posted about removing .100" of material from the base circle.

JBP posted about having 0.025" more lift than the original camshaft. Where the .100" came from was that the stock LSJ lifter can accomodate lash up to .090"-.100"...

mine is finally running good.. I'll cruise

JBP posted about having 0.025" more lift than the original camshaft. Where the .100" came from was that the stock LSJ lifter can accomodate lash up to .090"-.100"...

Is .025" the amount of increased valve lift or the amount of cam lift?

The .100" is pretty much the limit on the stock lash adjusters, I agree with as well. The first time I read that post, I took it to mean they actually removed .100" of material.

Increased valve lift is .025" as I understand it...

- Dyno's are on the part description available by clicking the link in the GB thread. Please note that even though there was only a 15.3WHP difference gain, this was during the time HPTuners was non-existent. We forsee better results with the advent of HPtuners and cam tuning. (You will run richer with these cams, therefore tuning is a must!)

- Our TriFlow mode specs are released for the first time! Please note that our TriFlow Technology contains a primary and secondary intake lobe profile. Revolutionary first in camshaft technology.

...Finally, the camshaft has rotated 180° and the lobe is now at the face of the lifter (full lift) and the lifter travel is now 0.425". (0.025" more than the original camshaft) No magic, no welding. Just plain simple physics.

Okay here's where we stand. Before I brought the car in for the cam install, I had a CEL with the DTC:

P0171 Fuel Trim System Lean -PCM

I made the assumption, based off of research I had done before installing my intake that the code had to do with a dirty MAF(Note: DTC occured after intake install), or more likely, the increased flow extending readings past the frequency available in the tables.

Well I just read the codes that this is what I came up w/:

P0172 Fuel Trim System Rich –PCM
P1182 Supercharger Inlet Pressure Sensor Performance -PCM

I went from Lean to Rich and now I have a sensor gone bad aparently. What confuses me is the obvious mechanical noises displayed by my non-functioning engine. I don't think changing a sensor would solve this issue, but it definately is a symtom. We'll see what Matt @ TTP and Mev @ JBP have to say tomorrow. I still have to take the valve cover off to inspect for valvetrain damage, but we definately are getting somewhere. Opinions are welcome...

171 means your MAF is calibrated 20% or more too lean. (not actually lean but 20% more air is flowing by it then it thinks). then the MAF calibration went an actual 40% in the other direction and threw the 172 code which is extremely odd. The bad SCIP could cause this, but I don't think both codes would be thrown. You could have a bad scip or maf really. Do you have HPTuners? I would unplug the scip and then monitor your fuel trims to see if they come back in the positive range. SCIP is only there to run checks to ensure the electronic throttle and MAF/MAP/TPS1&2 are working correctly.

Sounds very...uh...smartish tuning wise? lol

I went to Autozone today and rented a OBD II scan tool to read the DTC's. I love the idea of tuning, but never spent the money on HPT because I know I would do more harm than good with it. I've seen a lot of people blow their engines on here by trying to tune themselves. That's why I was going down to TTP in Jersey to have it dyno tuned. Safe measures, you know?

Basically, what you're saying is that the Inlet pressure sensor on the M62 is there to monitor several functions. By using HPT I could check the values on the fuel tables to see if they're running within proper paramaters?

Yeah, that is a stumper. I mean my understanding is the SCIP shouldn't influence air metering, but I would definetly unplug it for the hell of it and find some way to check trims after they relearned. All my logs and dickin around with hpt tells me it shouldn't change but to have the trim system go 40% in the other direction, it would almost have to. I dunno. Sounds like a 6 pack tuning session to me tho. :)

I'd buy you a case if you drove up from pitt, lol...

I guess I'll have to see what everyone else says...

Erik, if you could do me a favor when talking to Mev tomorrow. Could you ask him to kindly respond to my 2 e-mails (one is for the refund on the stock cores and the other is about my car problems), its been over 2 days now since sent. I also got your message and saw your post there. Thanks again for the update. As for me, no updates as of yet, should know more tomorrow hopefully, I'll keep you and everyone else posted.

Hopefully there will be some good news coming around soon for everyone. Otherwise...JBP is gonna have themselves ALOT of bad news for refunds and what-not.

Mev said he responded to your e-mail this morning. That is all...

Now all u guys who have the cams installed already still have the stock or GM Stage 2 tune correct? So the car runs rich already to begin with and with the cams it runs a little richer. Now I have the Intense Stage 5 tune in my car and possibly was looking into getting the GM Stage 3 computer. But if i keep the Intense Stage 5 PCM in it doesn't run as rich as the GM Stage 2 computer I know i could still possibly run into tuning problems as well but maybe not as bad because the car doesn't run as rich as a car with the GM Stage 2 tune. I would obviously still get it tuned but i'm just trying to think and add to what could have gone wrong. I'm no expert though

Shouldnt a cam lean the car out?

No..Cams are actually supposed to richen her up. At least that's what I have been told from our local Speed shop guru..lol

DONT GET THE STAGE 3 PCM. it isn't tuneable it won't work with 60# injectors and everything it can do hp tuners can do better. plus you'll loose ac with stage 3.

No..Cams are actually supposed to richen her up. At least that's what I have been told from our local Speed shop guru..lol

the cams have richened my car bigtime
