i want to free up some hp/tq with a exhaust system, mostly want more then a cat-back but can deal with it and get a high flow cat an the header to cat pipe changed. anyway though i want something that has good gains, but doesnt sound like shhhhhhhh, like a fart can. anyone have suggestions on this, i know on a 4 banger u have that given nasty sound but i want the nicest sounding good gaining exhaust. i hope that made sense

 

also has anyone dynoed the 2.4, it seems like it has alot more then 171hp same as the tq, i really need to get a lsd in her cuz it smokes the rubber with out tryin to much

 

also does anyone have a SCDyne header?

 

i am gonna dyno mine as soon as i break it in and ill be doing the snorkel removal before dynoing her as well ,i think they are underrated so im gonna find out i wouldnt be surprised if its got 171hp at the wheels

These are the dyno results of my 06 2.4L Cobalt SS Sedan stock...Now this was on an axel dyno (Front tires off of vehicle)... They said to about about 14.32% to the numbers to have an accurate reading of HP and Torque for my car... So thats 180.73 Ftlbs and 177.54 HP at the crank!! Not to shabby... Hope this answers peoples questions about how much power the 2.4L has!

 

06CobaltsSSSedan, is your cobalt auto or stick?

 

Auto...

 

can you post a pic of you car? Also doesn't an auto have more loss then a manual?

 

I defintely wouldn't get my hopes up that if I were you for those types of numbers.

We've seen dyno graphs here already showing ~158HP to the wheels, and the Solstice using the same engine but RWD instead of FWD is doing 146~150HP to the wheels.

 

I was talking to the GM Master Technician teacher at school the other day and he was saying that the auto pushes more torque than a manual.

 

I like hearing that.

 

hey average white boy how does the Monte Carlo SS drive? I have an 84 MC w/ T-tops Gonna sell it though

 

From when I got my car Dynoed the guy said that a automatic suffers much more loss than a manual, something about the shift points... On a manual you can shift when you need to so it dynos fine, but on an automatic the shift points are different and they need to adjust the dyno accordingly... Thats what I was told... Still I was very happy with the numbers!
