Anybody know these figures for a 3.3 930?
Bore: Cylinder diameter in inches.
Stroke: Engine stroke in inches.
Engine VE: Engine Volumetric Efficiency in percent. VE changes with engine RPM, a engine at wide open throttle at 3000rpm could have a VE of 90% and at 6000rpm 60%. This is a rough guide. At maximum RPM modified engines may have a better VE, eg: average overhead valve engines 45% to 75%, overhead cam twin valve 65% to 80%, four valves per cylinder 75% to 90%.
Standard Comp: The Compression Ratio of the engine.
Boost Pressure: Boost pressure in pounds per square inch.
