what gains can i expect from a new exhaust and CAI?

what about a SRI and new exhaust set up?

 

Depends greatly on the exhaust. The pacesetter from TTR is only 189.99 and it says it gives the 2.2 6-8 hp/7-9ft/lbs of torque. No word on the 2.4 yet. As for intakes I would expect around 3-5 horsies from the injen CAI.

 

not sure of the gains, but i dyno'd 148 whp w/injen cai and axle back exbaust.

 

On average on both Cobalt SS's and Solstices it seems this engine gains about 10HP to the wheels with a CAI + cat-back. Adding an ECU retune is on average netting another 10HP~15HP on top of that, but going to an ECU will then require 91+ octane instead of recommend.

 

so around 190-200 is possible

 

As of now there still hasn't been a cold air intake or exhaust specifically designed for the 2.4L. Many retarted companies have been like yo we'll make the 2.2L compatible w/the 2.4L. I emailed injen and they said they haven't even tested performance gains w/thier 2.2L air intake on the 2.4 engine nor do they guarantee any gains. Think about it. it's retarted. its like taking the ss s/c cold air intake and putting it on the 2.2L. doesnt make sense. wait till they make cai and exhaust specifically for the 2.4L then you cold expect 20 whp peak gains like the ones you can see w/the mazda 3.

 

superfly, i love you - make love to me

 

 

omg thats so leet, gay - sexually driven smiley faces!

 

the 2.2 and 2.4 engines are almost the smae except for a few internal workings, theres not much that can change from adding a metal tube to feed air the gains are great with injen so just buy it and find out, youll see

 

personally i don't think any combo of intake and catback exhaust will ever net you 20 whp...at least on a cobalt ss/na. Seems to me; after reading pretty much every intake/exhaust post/re-post on this site and having a few installed myself, you're gonna top off at around 10 whp.

No flaming...just the conclusion i've come to...and to be honest i'd be very happy with 10 to the wheels.

 

thats about right

 

I think u all are wrong. the 2.0 mazda 3 and the 2.3L mazda have completely different parts. the air intakes are different diameters and are curveded different. If you used a 2.0L cai on a 2.3L you will probably even lose horsepower. im tellin u all. wait till they design one specifically for the cobalt ss n/a and you will see good gains. 2.4L has bigger displacement and needs more air than the 2.2L

 

isn't a pipe with a filter just a pipe with a filter? i dont see that there could be a difference.

 

if there werent a difference then i could use a corvette intake on my cobalt. these guys specifically tune their air intakes for gains. i have no clue how. but they do. and i can promise that an air intake made for the 2.4L specifically will have better gains. otherwise aem and injen would just use there 2.2 for the 2.4 but they dont

 

its all the same, you just need to find an optimal place for the maf so the ecu doesn't freak out, and use a resonably size piping. It IS just piping and a filter so I really don't see how you could net more gains. I'm willing to bet $100 that an intake for the 2.4 will be routed the exact same.

 

k then just ask injen or aem why they dont already have piping for the 2.4L?

 

Because they aren't going to engineer another one because there's no reason/advantage to. There's a whopping .2l difference between the motors. And if you think they are going to route it different where the hell else is it gonna go? there's not exactly alot of options. And any bigger piping is going to hurt performance. If your so interested in the difference why don't you e-mail injen or aem?

 

With JUST an intake an exhaust, no, it's not. I don't know why'd you look at crank gains anyway. You should get around 145-150hp to the wheels with intake and exhaust. Right in line with what Brandon97Z got.
