Horsepower Design Equations and Formulas Calculator
Automobile - Car - Truck
Solving for the change in engine or motor horsepower performance using the trap speed method.

This method uses the speed or velocity at the end of a quarter mile run. It is used to give an estimate of vehicle(car, truck, motorcycle) engine horsepower. Weight should
include the mass of the vehicle, driver and passenger. Power will need to be measured before and after performance or after market parts have been installed.
Inputs:
Conversions:
| weight | = | 0 | | = | 0 | pound |
| velocity1 | = | 0 | | = | 0 | mile/hour |
| velocity2 | = | 0 | | = | 0 | mile/hour |
Solution:
| change in horsepower (hp) | = | HAS NOT BEEN CALCULATED | |
