Engine torque to Wheel torque calculation

[MvM]

Is there a way to calculate engine torque to wheel torque?
What I am looking for is a way to calculate (if possible) the amount of torque at the wheels taking into account the engine torque at a specific RPM and gear.
(This is to show some unbeliever why a car like the NSX with such 'low' torque can & will outrun a diesel-engined car which (officially) has much more engine-torque)

Yes, just multiply the engine torque at RPM by the gear ratio and final drive ratio.

Or multiply the Horsepower by 5252 and divide by the RPM of the tire.

Or multiply the Horsepower by 5252, by final drive ratio, by trans gearing, and divide by the RPM of the engine.

All three will give the same result, but did not subtract for frictional losses.

1BADNSX,

Thanks for the info.
So, say 100 lbs of torque in 1st gear (3.071) with stock R&P (4.062) would give 1247.4402 of wheel-torque.
In 5th gear (0.771) it would be only 313.1802 lbs.
