How fast at what rpm for what gear ratio?

Engine RPM / gear ratio = tire RPM

Pi x Tire diameter in inches x RPM of tire = inches per minute x 60 = inches per hour.

inches per hour / 63360 = miles per hour

Pi = 3.1415926
----------------------------------------
Rear end gear ratio is multiplied by the transmission gear ratio.
The gear system is a torque multiplier. With zero mechanical losses in the system, the HP will remain the same from Flywheel to the axle shafts, since that never happens rear wheel HP is always less than engine HP.
