I am really freaking tired but I will try to put that video together later tonight

 

That is awesome. I hope it wasn't a mis-calibration. Could you imagine what the stage kits will do!?

For once in my life I can honestly say I want to be a freak.

 

I dynoed on the same dyno today and did 231.6 @ 6250 with a 4th gear pull stock. Maybe not freakish, just good exhaust.

 

The numbers do seem a little high. I have been doing a lot of reading on these forms that said chase dynos are not the final say all and can be misleading. I guess they talk about how it is just a tool to see the before and after of an upgrade with some margin of error still present. Still the same I would like to give you guys props for the numbers you are getting with the upgrades you have done.

 

Very true, as long as they are calibrated correctly and the weather conditions/correction factors are similar.

 

Nice numbers!
In my experience with GM's through the years, there are some cars that can only be explained as factory freaks.

When I lived in Tennessee, my roommate had a 93 Cavalier RS 3.1L/5speed that was running the 1/4 mile with 5.0L Mustangs and winning (!!!) without fear. He was so arrogant about it, he'd laugh at the 4.6L guys and tell them they weren't worth the gas racing. i have never seen, before or since, a 3.1L that ran like that car did!

The #'s where corrected. He said it helps when people come in in the summer and the winter and gives the same #'s year round. There was a fan blowing on our engine bays, and they did allow the car's to kool down after each run. My car was sitting off in the parking lot for a good 2 hours prior to that 250 pull. The 249 pull was right afterwards with about 3-5 minute kool down.

IM saying mine seems to be the factory freak because my brother has an

INTAKE and EXAUST (bigger exaust no resonator) where as all I have is a Magnaflow cat back and I pulled higher HP #'s then him.

also Merc Has an INTAKE and stock exaust but I beat him too, where a Intake is supose to provide more horse power to our cars then exaust is.

also here is the a picture of the dyno used, and the name on the top of the sheet if that helps. He said he had dyno'ed Cobalts before and all three of us where higher then the rest. He said most average arround 230.



He also siad something about having a newer mustang dyno and that they are very similar in test results to all dynos now, he said older dyno's seemed to provide different #'s then other brands, but said most of that has been done away with recently.

 

i like that keyboard... a lot.

 

Thank you its the Saitek Eclipse keyboard, if you look at the W A S D and SPACE keys, you can see some wear from my heavy FPShooting... Anyone ever want to go against me in some UT holla!

 

so why is this guys numbers so believable and my 253 with a 3" pulley, intake and muffler so unbelievable?

not to bash your numbers but when i posted my 253hp/221tq i got so much **** saying that it just was not possible to make that much with my mods.

 

What about the bad ones of this forum migrating over there (Xenozx)?

Tricks are for kids

Pretty obvious also since the damn 1/4 timeslip is on printing paper! Someone has way too much time on their hands...

 

IM not sure I understand your post?

I was thinking about buying an SRT-4 before I bought my Cobalt SS....



anyway I just posted on the thread that was already created. What amazes me is how everyone decides to nit pick on the details. There is a whole other thread in this forums that has pictures and videos of our dyno day. The quarter mile times where done on the dyno. They are simulated. I dont understand how that means it was ran through ODB? WTF? Get a life, this is what I pulled, there is no if's ands or buts about it. All I know is that we asked arround and where told thats one of the best dyno places arround, we went there we dynoed I pulle 250. end of story. I am not spreading any false info, I am showing you the types I ran. Simple as that. If you dont like them or believe them thats on you, what do you think I did forged my paperwork? jesus, I dont have time for that ****, plus I have 4 witnesses....

 

Nobody doubts that the dyno spit out the numbers you are posting. The problem is that it was several cars that far exceeded anyone else's numbers on stock cars (also more than more heavily modified cars).

One that far off is a strong car (especially if the other two show more reasonable numbers). All three means the correction factor (which the operator of the dyno selects) was wrong. Consider this; if a particular dyno consistantly spits out higher numbers than the dyno down the street, who do you think it going to get more business?

Bottom line is that as an absolute number, comparing dyno numbers from one place to another is pointless. They are only good for seeing improvements after mods (using the same machine at the same location of course).

Your car does not have 250 horses at the wheels. Sorry, I know you don't believe it, but it is the truth.

 

yo, where is this place, is it in pa? cause if it in aston his #'s are bs

 

I hate to say it. But stock with 202.9 wjp I pulled a 14.5. with those numbers your trap speed should be higher and your time faster then 14.7

Stock - 202.9hp @6300 and 191.9tq @3800 11/19/05 Eddie current Mustang Dyno

what about em? i haven't seen Xenozx post anything over there that would be considered trolling or trying to start crap. every forum has their turds, and the srt forums are quite a bit larger so they tend to have more. but there are quite a few srt-4 guys here and most of em are pretty cool. i cant say all because i dont know them all, but i havent seen any of them start anything yet.

im talking about those guys that absolutely cant believe that an SS/SC beat an SRT-4 and call BS all the time. the guys whos most intelligent response is "GM sucks!.....Mustangs suck". maybe if some of the guys on other forums would be a little more open minded and realize the srt-4 wasnt build by the hand of God, people wouldnt have to be so defensive when they post over there. there are a lot of cool, knowledgable people over there and some of them post over here and are great contributors.

listen, i find it hard to believe that these numbers are accurrate, and i dont driver a cobalt or an srt-4. but i was able to state my opinion without being a jackass. i do the same thing when i post on the srt forums. i didnt come out with guns blazin calling BS, simply said they were impressive numbers but seemed a little high.

so i say Xenozx, i find your numbers (especially on a mustang dyno) hard to believe, but im not gonna call BS. i hope they're accurrate because that would be awesome for you man.

see? you can disagree without calling BS and being and ass. its pretty easy. the reason other car owners come off as trolls over there is bc the second someonesays "i beat an srt-4", all the hounds come out with their BS flags and start ****. they just can't disagree and have an intelligent conversation about it.

 

Dyno is a tuning tool. Use the same one for before and after mods for best results.
That's it people. This reminds me of dieting women at the gym that only go on certain scales because "that is the only accurate one"( on the others she is fat ). I am not calling BS on anyone,but a 250hp Cobalt should be in the 13's.

"factory freak" there is no way that GM manufacturing processes could make a 20% increase in horsepower by fit and finish. There was a time ( I feel so old)when human hands were building the motors, that how you put it together could give you better performance. Bolt torques,adjustments, uniform quality of parts ect..... This time is long gone, most things in manufacturing are plus or minus 3%, the horsepower on our cars will be no different. The whole "GM underated our cars for insurance reasons". GM did not care enough about us to build a decect radio antenna into our car, but they underated our cars to save us money ? If they could have had bragging rights to a 225-230hp motor in car that they were launching do you really think that they would say 205? Stage up grade kits on sale first quarter 2006 but "free" 20hp for buying a new Cobalt...not.
I guess when you dyno a new Vette, it will be 575-600hp to the wheels.

I assume some of the "bench racers" are going to flame me for attempting to bust the "underated myth" but seriously think about this GM goodwill act. There was a great link to a story about dynos and BMW but I do not remember it. Not calling BS on anyone,just wanted to contribute some information.
Post is long enough, still put out milk and cookies in a couple of weeks
Peace

 

i thought i remember always reading that a Mustang Dyno reads higher than a Dynojet so i think that might be about right for a HP reading.

 

Umm, it said Aston, PA on his dyno sheet that was shown on the first page of this post.

Why would this places numbers be BS?

 

its the other way around. Mustang Dyno's read lower than a Dynojet, which makes the accurracy of the #'s seem questionable. (still NOT calling BS guys )

 

I think the majority of people understand that there are tons of variables to consider on any dyno. The point is, like many said, that it's a tool to measure your gains/losses (among other things like A/F, etc) from modding...that is all. If someone's dyno run spits out 250whp then good for them IMO, mine was 220whp in 4th, my feelings weren't hurt when I saw his dyno sheet. Between calibration, weather, crappy gas, hamster was tired, whatever, there's just too many factors involved to sit back and get all fluffed up about not making the same whp as someone else with less or the same mods. Now I'm not at all saying some of you are jealous, but give the guys a break! We all know the true testament of a car and more importantly, the driver, is the track. And if my car runs a 14 flat and makes 220whp and he runs a 14.7 (just an example) and makes 250whp then I'm one happy camper. I have plenty of friends w/ LS1's that are only slightly modded, and out of the three who have A4's, the one who dynoed the lowest according to his particular dyno is the one who consistantly runs the best times @ HRP raceway.

 

well call this shop bull all you want but "HE IS ******* WORKING WITH SEMA" not some guy off the street he owns 5 shops in one corner

he is also getting cobalt SS, redline, and SRT 4 parts this year for testing and will need us to help so stop flamming the guy, go up there yourself and get dynoed and see how low or high ya pull and shut it

bunch of haters lol

the guy told me he was surprised my brother made more hp cus my car and merc pulled harder inside the car but his was alot smoother. he is a factory freak in my opinion due to the fact he pulls a car on me in 3rd then 4th i have to catch up, ive seen his car in action and have driven it so i know plus he is a 2006 model with G85 (i thought they got an extra 10 hp) the redlien version does atleast. merc was a 05 and im a 04

the 03 SRT-4 was like 215 whp, 04 went to 225 wjhp ,then the new ones are 230+ and i beat them easily if there stock without staged upgrades so are numbers are quite reasonable.

 

because they are. a guy dyno'd his lightning at evolution and then at collingdale performance the next weekend. both mustang dyno's, one eddie current one enertia. he lost 70hp from evolution to collingdale performance. they guy there is a tool. I bet he just used the wrong correction numbers, and he does it just to get results like this.

 

you know im almost sorry i posted over there....i just did it to inform them of higher hp numbers, thought they would be interested to see.....insted i get accused of being a troll go figure, if i dont troll over here Why in hells half acre would i do it there??
