go to www.download.com search for virtual engine calculator.
ive used it for years in kart racing.( bug and virus free)
its got a dyno pritner along with HP TQ RPM MPH and CFM

if you know what to do, and know how to hit the calculator, you can figure out
CID
compression
compression height
gearing
MPH
piston speed
HP
HP head flow
rpm
ET from power
power from MPH carb CFM
altitude correction
weather correction
unit conversion

example what is my final gear at 70MPH in my car? well the ford number is 2.70 (5th gear)
2300RPM at 70 MPH with a tire dia of 27 inches im moveing at 102 FPS 14.5 tire rotations per second at 2.64:1

but like i said you got to know how to crunch your own numbers to get "theoretical" numbers back out of it!

not too many computer programs I trust, but I'll give a try.

let me know how you like it

you jsut got to know how to use a calculator. its dead on

i did my car

for example my final drive ( 5th ) gear is 0.72

multiply 3.73( rearend gear) by 0.72 (transmission 5th gear output) and get 2.6856 thats my 5th gear ratio!

so in the MPH calc you put in say 2000 rpm at a ratio of 2.6856 ( because thats what i drive on teh highway with )
and my tire diamater of 27 inches and i get 59.84 mph!
