"    Volumetric efficiency is the best measure of an engine's air flow"
"    capability at a particular RPM.  High VE is is critical to obtain"
"    high torque and HP.  See page 51 for a definition of volumetric"
"    efficiency.  Most all engine specs affect VE and the RPM at which"
"    peak VE occurs.  Generally, engine torque will peak close to the"
"    RPM giving peak VE."
