some guy in NJ was looking for a 2.2 balt to tune it with HPT. apparently, the 07 pcm is very close, or the same as ones where tuning is available. i would just wait it out.

yea im not sure. i was just tryin to say i mean the temps were high but it wasnt that bad and the same car with less mods ran a half a second faster lol. i mean my 2.4 vs my friends 2.4 he ran a 15.2-3 and i ran a 15.5 but i couldnt get traction

the 05's and 06's were suffering from a drop in torque. the 07's run a little different and they were having MUCH better success with the manifold. I made the point the other day that torque was lost at like 3000 rpm, but ultimately you ended up with more and much higher hp numbers in the high end. The way I see it, you aren't going to miss that torque on regular cruising, and when you need to go, you will mash the pedal, down shift and throw the car up to about 4-5k RPM's as the auto's do on acceleration. and at that point you are in the new powerband and back to good torque numbers.

i dont know if i typed that clear... you get what i mean?

chevysalesman614

yeah.

fbaero10

yea i know what you mean. i mean honestly lol he cant get slower.. lol so its worth a shot. but now since he is a 07 would he use the 05-06 manifold or 07 or doesnt that matter?

chevysalesman614

if it is that big of a deal to get rid of the plastic one, why not go with a sheet metal manifold like hahn made (IDK if this would affect that silly SRI that the 2.2 guys talk about)

OrngBalt

year of the car matters, the manifolds are all the same.

fbaero10

i was actually looking into getting a different intake manifold. if i got hahns would that actually help me out a bit?... i mean with a dry shot im sure it would be good.

OrngBalt

its not getting rid of a plastic one cuz the 2.4's are plastic as well. they are single molded piece (better for adding nitrous later) and are a little larger.

That would really mess with his low end torque because of how much shorter the runners are than the stock one.

fbaero10

do the make a non plastic manifold that i could put on my car?

XM15

For a decent price, not right now. That Hahn one is very expensive and would only benefit you if you went f/i. The runners are way too short for an NA engine that revs only moderately.

fbaero10

oh ok. i want to get to low 14s without a SC or turbo.. im gonna get every bolt on. the vector tune. and a 50 shot of nitrious

i had the 2.5" cobalt addiction downpipe. didn't get any codes from it though. you can take that one off no problem.

one thing i DID notice on the 07 2.2 (this was on a G5,but i think would be the same one the cobalt) is that along with the 2nd cat, there now is a 2nd 02 sensor as well.

kloppster

yes there are 2 O2 sensors

OrngBalt

oh great, now i look like a dick who know's nothing. Thanks Kev

fbaero10

oh alright. i mean i was thinking if they are selling the part for the 07 cobalt its gonna come with whatever it needs to run they wouldnt sell a product you cant use.

kloppster

i think what im going to do is next time i get a chance to go to my local exhaust shop im gonna get them to custom make me a dp with 1 high-flow cat and then make it cat-back

fbaero10

ORDER ONE lol dont go to gehmans atleast order a downpipe... once you get that then go to them to put it on and then do a catback

OrngBalt

yea bro, i would order. get some parts tuned and made for our cars. it will only benefit

kloppster

the only reason why im thinking them to custom make one is because i dont think i can find a dp that has 2 O2 sensor ports

fbaero10

LOOK ONLINE FOR 07 cobalt.. and it will come with what you need.

lol your car isnt rare its not the only one. they have to make certain parts for the cars.

DC52NV

you have an auto and muffler (not even catback). you also had on 17" wheels that are more than likely heavier than your stock ones. come one man, common sense would have told you this. not to sound like a dick or anything but if you just buy a muffler for looks and sound you shouldn't be going to the track and be worried about your time.

fbaero10

lol! good point, but we are just saying there was a car there auto with just a muffler not even an intake running a half second faster and he even gutted his car

D4u2s0t

haha, my bad bro. i don't think many people at all know this, so don't feel bad. i only know because when i sold someone my downpipe i was looking at his car and saw it. otherwise i would have had no idea.
