Sup ppl i have a 07' Cobalt SS 2.4 auto (stock 4 now) Well i have just ordered a bunch of stuff such as a GMPP cat back, Injen CAI, XTC Downpipe w/ cat 2.5, CA header...So does any1 have any ideas on power gains? o yea i just switched to mobel 1 (i'll have pic's of my car in about 2 weks when i get home )

 

rough estimate you should be sitting at about 195 - 200 HP (feel free to correct me if im wrong guys). but welcome and have fun moding your cobalt and pics please.

 

180 Crank, 150 wheel. Better tune will net you a few more horses.

 

I had roughly 150 wheel stock.

 

Yea ill get pics asap but with my job iam away from home 2weeks @ a time so ill get pics up after the 9th. i orded my CAI from cobaltperformanceparts.com 2 WEEKS AGO! and nothin... thier phone is off and they dont respond 2 emails iam kind of P!ssed

 

he has an auto... more drivetrain loss

 

O yea i also have installed already a set of eibach sportline springs they droped the car nicely and my dad an i did them in about 2 hours

 

oh yea gotcha.

 

Did you add the DP and Header into those numbers, cuz that seems a little low. the 06's have 171 - crank and the 07's have a 174 - crank so having all those mods and only a gain of 6 to 9 HP at the crank is a little off. now my initial estimates were probably a little high and dependent on my city. now the intake and exhaust will probably net him 10 - 15 HP at the crank alone now im not familiar with the gains with the DP so i just took a wild guess on that. so with that out of the equation that would still give him a minimum of 180 - 184 at the most 186 to 189. (these numbers are for intake and exhaust only and again are rough estimates) and as always feel free to correct me if i am wrong as i always like having correct information

 

Cool! Can't wait to see some pics of the car!

 

Actualy I'd say the 190 to 200 flywheel hp is more like it. You'll probly be in the 170 to the wheels range. 20 hp from all those mods is not unrealistic.

 

Doesn't matter what mods you have. an air intake on an n/a 4 cyl car is less than 3-5hp unless the stock system sucks that bad and exhaust? please.. 1-5hp.. I will be nice and say 160 MAX whp. I still say 150whp since they dyno so low to begin with.

Crank I still say the same numbers from before. It's been noted a tune can wake this car up for a few more horses but not to justify spending $100 on credits or $400-600 on the tuner application.

 

Unfortunetly the GMPP intake has been dynoed to gain around 8 to 12 hp. The GMPP catback has been dynoed to gain around 12 to 15 hp. The CA header was dynoed on a 2.4 and they had gains of 8 to 10 hp and I'm not including the DP he says he's getting.
Thats why I say a 20 hp gain is realistic, your low balling these mods and since dyno #'s have been posted I can say so with some confidence.

 

thanks jackalope even i thought i was being modest with my calculations.

 

Welcome

PS turbo it!

 

I thought bout turbo but all my mods now would be worthless so i think goin S/C in the future is next

 

ya either way you go. both s/c and t/c will give you excellent gains

 

Your off to a good start, what color is your car?

 

Black

the only pics i have are on my myspace...lol

my pics from myspace

if that doesnt work got to myspace.com/seangherman

 

More like really close. Just cause 1 mod may add 10 hp doesn't mean you d up the total gains and thats what you'll get. It doesn't quite work that way unfortunatly.

 

very true thats why i was giving a range but oh well you live ya learn right.

 

FILE A PAYPAL COMPLAINT WITH Cobalt performance parts. he is taken eveyones money. I almost lost 3500$ but paypal got it back.

 

Lol i under stand that

DAMN IT! now iam pissed. any 1 know a good place to buy the Injen Intake?
