ok im a little pissed off....i am shopping for a few things for my car and i keep noticing that any part you look at for the SS comes with a dyno sheet.
what about us 2.2L guys?!?!

perhaps we should start boycotting the manufacturers that DONT post them on their sites. i bought my 2.2L cobalt for the purpose of modding the **** out of it and yet nobody can do me this courtesy?!

Anyone have a dynosheet of before and after a mod, ANY mod, please post.

yeah the ss/sc gets all the attention but you had to expect that anyway.

 

Anyone know how much the injen hydrosheild is

 

damn 123hp at the wheels with the injen, im so disappointed i swear it feels like i had more then that.

Its supposed to suck ***** compared to corsa, borla, and magnaflow but they are the only ones who offer a dynosheet...hmm maybe the others are hiding something.

**** the aftermarket vendors who only support the SS/SC

 

well on redline tv didnt the base balt with injen short ram and borla cat back exhaust(2.25inch) make about 140 whp?

 

a guy in a 2.2 Ion hit 132.5 HP/144.7 lb.-ft. of torque at the wheels on his last dyno.

he has the following mods:
AEM cold air intake
62mm throttle body
Pacesetter header
high flow catalytic converter
2.25" Thermal R&D exhaust

 

Doesn't GM tout it gets 140HP? why such low power to the wheels? You would expect to at least get 150whp with all that.

GM Site

This Twin Cam, 16–valve powerplant produces 145 horsepower and 155 lb.–ft. of torque

 

GM what?

thats an increase of 12HP and 21ft lbs of torque...I thought the wheel HP would be higher but thats an awesome TQ gain IMO.

 

yeah those are good gains and if we could tune our cars for I/E the gains would be much higher

 

aem intake.....dc sport ceramic header...NOPI carbon fiber muffler coming from a 2.5 pipe from the cat back....airaid tb spacer.....This will give you 150whp. Maybe 155 since the cobalt 2.2 starts with 5 more than the cavalier. I got 150.4whp on an 05 Cavalier with those mods.
