The following two calculators can be used to estimate the horsepower of the car's engine based on the vehicle weight, elapsed time, and speed used to finish a quarter-mile distance. The weight of the vehicle should include not only the car but also the driver, passenger, and any other significant weight. To estimate the maximum horsepower output, the maximum output from start to finish must be applied. All calculation results are estimates.

**Elapsed Time (ET) Method:** This method uses the weight of the car and the elapsed time (ET) to finish a quarter-mile (402.3 meters) distance according to the following formula:

Weight / (ET/5.825)^3

**Trap Speed Method:** This method uses the weight of the vehicle and the speed at which the vehicle covered a quarter-mile (402.3 meters) distance according to the following formula:

Weight * (Speed / 234)^3

The speed used should be the speed reached at the quarter-mile point, not the average speed.
