Relatively inexpensive program made by Mr. Gasket that allows you to set up engine parameters and test them virtually for power/torque, etc.
Demon, in that message I sent you, I was thinking of
Performance Calculator , which is significantly more expensive, albeit a MUCH better program. It goes for $649 (the Pro version), but is well worth the money if you can afford it. I think you get free updates to newer versions with the price of admission.
