Performance Calculations and Formulas

The Horse Power Calculator below will calculate your approximate horsepower based on the vehicles weight, 1/4 mile time, and the 1/4 mile speed.


The calculator will spit out four different HP numbers.
(Extremely averaged drivetrain losses)
5-speed front wheel drives (using a drivetrain loss of 13%)
Automatic front wheel drives (using a drivetrain loss of 15%.)
5-speed all wheel drives (using a drivetrain loss of 18%.)
Automatic all wheel drives (using a drivetrain loss of 23%.)


This program averages the HP results from your 1/4 time AND speed. There are sometimes inconsistencies in the numbers. This will minimize this errors from an incorrect value.


The results are only approximate calculations.
