i was thining a bigger heat exchanger. what would be the best bang for my buck?

 

You're not going to get any power from the h/e. I say ls4 throttle body and spacer with hp tuners adjustment to idle airflow.

 

Header and tune.

 

throttle body gets you nowere. i say clear image header and downpipe, it makes a huige difference in the car.

 

Yeah...right.

 

with the mods he has a bigger throttle body isnt going to get much power, just make the throttle touchy. feel free to post dyno charts to prove me wrong. and yes the clear image header does make a huge difference. i have one on my car and i gained a lot of low end torque and it pulls a lot harder over the whole rpm range.

 

How would a h/e not give him any more power? Last time i checked cooler intake temps means more power.

 

thats what i was thinking.
