Screen shown here is trying around 160, 000 combinations to come up with cam specs to produce the highest Peak HP on this engine, while maintaining at least 9" idle vacuum. The Engine Analyzer lets you simulate an engine build-up or modification on your personal computer. It let's you play "what if" with cams, heads, intakes, superchargers, etc. and see the effect on torque, HP, fuel flow, air flow, valve toss or lifter pump-up, idle vacuum, cranking compression, spark knock, etc. "Its like having a dynamometer right in your computer.
