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.

 

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.

 

People like you take all the fun out of nagging.

I love new smilies

 

 

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.
