A simple Desktop Dyno 2000 program available at most Autozones is the best simulator I know of.

Otherwise, I observe many other peoples setups, ask questions where I need to be filled in, and gauge my vehicles' performance by either a timeslip or a small pull along side a solid benchmarked car.

For instance....Naturally Aspirated engines....generally speaking...require 9.5:1 Compression a camshaft with more than 264* of duration and lift of over .450" to obtain 1hp/c.i. with adequate fuel distribution and a free flowing exhaust system.

All engines are comparitive to Air Pumps. Air+Fuel=Hp/Tq, the more air and fuel you get in/out the more power you make.

I like Desktop Dyno for plugging in different values and seeing how it affects the curves.
