how much horse power can i expect from a air intake and exhaust with tuned ?
also what is the biggest pulley that you can put on the car on stock injectors?
or would a better route be bigger injectors tuned ?

 

a million...damn it man...do it and dyno and chill...tunes can get all sorts of different ponies, and coming from RACELAND, nobody knows your air temperatures and humidity levels.
do a 3 for the stockers
yes, man. of course.

 

With intake and exhaust you would probably see about 10-15 hp, unless your doing full exhaust and not just a cat-back. It would also be wiser to go with bigger injectors and a smaller pulley, that way you can safely see some nicer gains performance wise.

 

10-15 yes with a tune it should be more and for the pulley its either or ...... i was thinkin with injectors tuned it would be like gmpp stage 1
the dynos around here are to far to drive and waaay to expensive

 

LOL Go with the intake, exhaust & tune 1st. you will be looking at around 20 whp

 

Why would you put a bigger pulley on your car?

Just get hptuners and run 60lb injectors and a 2.6/2.5" pulley

 

not enough money for that


the intake and exhaust is going on there

besides those two im deciding on what to get ?

 

skip the intake AND exhaust and get a stage kit (either GM or aftermarket).

if you have money for intake and exhaust, you will most likely be able to get a stage kit. you will have much better performance gains. then go the route of intake, exhaust, and custom tuning. just the way i would have done things if i could start over.

of course you have have may personal preferences and reasons behind getting the cai/catback first. whatever suits your speed fix man

oh, and to answer you questions:
- 10 to 15 hp would be my guess. a bit more if tuned (get a smaller pulley if you are getting tuned)
- i believe a 3" pulley is the smallest you can go on stockers
- bigger injectors and smaller pulley with tune, as i said, would be your best bet by far.

 

I would do intake first because it jus sounds so good...from wat i heard. Why get a tune wit jus exhaust and a header cuz thats jus a waste of money. I want a pulley but il probly end up gettin it last cuz im gonna get a tune along wit it. Do you guys think I should get exhaust if i get a 2.7" pulley. I don wanna spend almost 500 that wont sound a lot better or make my car much faster.

 

ya for the price of an intake and exhaust you could get GMPP stage 2 and slap on the 2.8" pulley.

 

I agree I would go with the stage kit first because the factory exhaust is capable of supporting up to 300 HP. Doing the air box mod is pretty much just as good as doing a CAI.

 

WHIIIIINNNNNEEEEEEEE

 

wow i can get a tune and injectors for about 300-350 bucks or i can spend 700 for a stage two
hmmmmm 400 bucks for 15 hp

 

I completely agree, if your going to get a tune for the intake and exhaust, you might as well throw a smaller pulley on as well.

Another good idea/option. You'll feel the performance gains better here.

 

I just ordered my stage two. I can attest though, that the exhaust is nice. It might be in my head, but it sure fells like a few ponies came out to play.

 

thanks for the input guys ........
i will be getting the stock muffler cut-off and having magnaflow put on for 50 bucks i have the airbox mod i had it dynoed on a portable dyno with 218 hp with the air box modd
which would produce the most horsepower bigger injectors tuned or a 3.00 pulley tuned ?

 

GO FOR THE STAGE 2. it s about $750 list but I don't think anyone here paid that. I could be wrong. the CAI and Exhaust I'm sure will amount to at least that. And the CAI is practicly worthless on these cars, your aren't going really feel a lousy 15hp anyway. its all in your head if you do. GO FOR THE STAGE 2! I Don't see any reason to discuss this any further. U need the STAGE 2!

 

buy the ebay cold air intake for cheap and get 60# injectors for $230 and 2.7 pulley from zzp. + $100 tune. all that for more or less 500 bucks.

 

stage 2 for the win...

 

whos going to tune my car for 100 bucks
