Engine Horsepower Calculator 1.2

The Engine Horsepower Calculator serves as a useful tool for estimating the horsepower of a vehicle's engine, taking into account the weight, time, and speed required to complete a quarter mile run. The calculation considers not just the vehicle's mass, but also the weight of the driver, passengers, and any additional load. It is important to note that the results provided by this calculator are estimations and should be used as such.

Horsepower Calculation Methods

• The ET Method: This approach utilizes the vehicle's weight alongside the elapsed time (ET) taken to cover a quarter mile (402.3 meters).
• The Trap-Speed Method: Here, the calculation incorporates the vehicle's weight with the finishing speed recorded at the end of the quarter mile (402.3 meters).
• The RPM Torque Method: This method relies on the torque specifications found in the vehicle's manual, with the RPM reflecting the maximum torque output.
