Since enginuity is still down, I thought I'ld repost my compressor map summary. Most of the compressor maps were downloaded from www.stealth316.com. I rotated and scaled the maps for easier comparison.

The demand curves are based upon 2.5 liter engine. 2.0 liter cars should enter the correct displacement in cell B2. Also, the volumetric efficiency is roughly calculated from a 2005 LGT. You might want to change those numbers.

Thanks to ride5000 for letting me store stuff on his server.
