True, The Only Way is that Somebody has to prove that. I am sure in time it will be proven. I am sure it might be close if somebody has S3 Cams with 2.7 Pulley on M62 and Meth or Nos. It's possible.

 

I doubt it, honestly id be surprised if its 20whp gain.

 

LMAO! You're Cracking Me Up Right Now, Who knows but hopefully Someone here will prove us wrong.

 

You obviously haven't read the ecotec hot-rod article.

You're dumping ignorance everywhere and it's spilling on people. Go sit down.

 

Please on great wise one that went from stage 2 cams to stock show me the error of my way.

 

I sold the s2 cams because they weren't enough. Hadn't settled on custom grind numbers so I threw the stockers back in. Big whoop. My new ones are similar to mrB's.
anywhooo, thanks for acknowledging my wiseness. Ass.

Here's the link you asked for.

Stock cams
"the engine generated 229.5 hp at 5,900 rpm"
Custom cams
"The peak power point jumped by 700 rpm to 6,600 rpm, where the new cams generated 265.2 hp"

It seems they are using crank hp and they didnt even take the lsj to redline for the first dyno run so its invalid info. iv seen stock dyno sheets that show peak power on the lsj at around 6400-6500 so its around 500ish rpm short of making its peak power.

 

Vander, I think I know what You are talking about. That Guy comparing 3 Cams on Dyno, Stock, GMR, and 252 Cams. Right? I remember that thread back then, the thing is that He use His same set up. If He were to pulley down He will might gets some benefit out from those Cams but He didn't.

 

Decent article tho. Would have been nice if they did cooling mods and small pulley on m62

 

Yeah True, I think He didn't have the Money cause He blew it all on Cams. Maybe He didn't realized that He can do more with those Cams with different ways of set up.

 

I have a hhr ss with a big turbo kit ect
Before the zzp stage 1 cam with bigger lobe I made 375 on a e85 mix I could not run full e untill I did the cams now I make 465 so my gain was way more than 20 hp I think it was worth it

Was going to erase it but don't know how sorry lsj thread

 

It's alright but at least We can get that Infos. Appreciate it, Thanks

 

Not custom cams. Reading>you. Off the shelf blower grind. Only thing "custom" was they were ground on lsj blanks instead of l61.
The whole point, anyway, is that a 40+HP gain from cams is completely reasonable, especially on a setup that has much more air to expell (ie-small pulley).
A grind like mrB's is going to have a huge gain.

 

Here's the link that ^ He just post HotRod Ecotec used that Comp Extreme Cams.
113200 - Cast core version Hydraulic Roller Camshafts
But MrB got much more than that! Hey Yo MrB, When You gonna do Yours ?

 

This is getting me thinking and I like the discussion. Thinking of the TVS cars that have had cams, infa, advise, blue, the other nick that is banned and maybe a few others, haven't dynoed yet. I know area made 370 something? I'm not sure if he was running cams with that set up or not.

 

Are you stupid? Quote from the very article you linked.

"The listed catalog part number is intended for most normally aspirated Ecotecs that use dissimilar-length cams, and won't fit the LSJ head, so as of this writing, the LSJ version is a custom-order part."

You also didnt address the fact that they didnt take the car to redline on stock cams, the whole thing is inaccurate since they didnt do the test correct to start with.

 

That was as of the writing of the article. That is no longer the case. Do some research before you pop off again.

I guess I should know by know that your opinions must be more accurate than a lab test. Show me a completely stock motor dyno peaking at 6500+
Oh wait, they don't.

Don't you have something better to do than push your ignorance onto others? All you do is stir the **** in every thread you enter.

 

Alright, Alright Guys. Don't need to Argue Over this but keep in mind We all have different opinions here. What's the point Arguing Over for Cams. We are missing the point about Cams. I just want to hear who has an experience with those Cams. I don't care about what hearsay has to say. The Point is All About Cams. Alright Guys?

 

I'm trying to be polite yelcal. It just doesn't get through to some people...

Anyway, I feel the smarter members here have answered your questions. Is there anything else you'd like us to dig up?

 

i like how all the same information is given back and forth none stop on this thread...

 

I know. Anyways, Back to the Point! All about Cams Folks!

 

What else do you want to know man??

 

If I were to do NBS on Stage 2 Cams, Will I need ATI Pulley to control it ?

 

Not at all. The ATI controls harmonic vibration. The balance shafts are there more for NVH. GM deletes them also on their builds. Or did at least.

 

Not sure. I don't have experience with the ATI pulley.

If you don't rev above 7.5k you won't need NBS, but I think the S2 cams make peak power around 7.5k so it will be close.
