Crap, figures I can't spell R-E-S-U-R-R-E-C-T correctly! :P

Wouldn't that be adiabatic efficiency Ted, which dictates temperature rise per compressing, rather than volumetric?

And god said to the forum, "let there be old threads," and there were old threads.

X-JaVeN-X

you guys kill me...if he'd of started a new thread...everybody would be yelling 'SEARCH YOU B*TCH @SS NEWB!"

lol...I'd rather him restart an old thread than make a new one.

lower compression doesn't always mean more fuel and air as with higher boost doesn't mean more fuel and air. the v/e of the motor will affect both as does turbo selection. For example a 5.7 hemi compared to a 13b is generally considered to be a more efficient motor and will respond to boost with better results that a motor with poor v/e. There are too many factors involved to give a good average estimate on what 1 pound of boost will yield in a given application. To answer your question in a stock s4 with no flow mods done you can expect about 8-10 flywheel hp per pound of boost. Subtract about 35-40% of that and that will be close to what you get to the ground.
