Power Calculation

The power calculation in the performance window calculates horsepower based on observed quarter-mile performance. Power is calculated by both elapsed time and speed. In real world quarter-mile performance, the calculations from both ET and speed will be very close, as shown in the example below.

See the power calculation or the engine simulator for a more accurate, mechanical power calculation.

Power Calculation

Enter quarter-mile elapsed time, quarter-mile speed and vehicle weight. Calculate power based on elapsed time and power based on trap speed.
