Vehicle weight in pounds (including driver)
lbs

Trap speed at end of 1/4 mi in m.p.h.
m.p.h.


You are making : HP at the rear wheels and HP at the flywheel*.
 

*Note:  Assuming a 18% drive train loss.

 Gear Ratio

This calculation assumes the car's transmission is in drive or 1:1 ratio, no overdrive. For Overdrive mutliply the overdrive ratio times the rear and gear ratio. Example a 5R110 transmission has an overdive ratio 0.7:1. For a 4.11 rear end multiply 4.11 x 0.7 = 2.877. Enter 2.877 as the number for the gear ratio to calculate speeds in overdive.
