Engine Motor Horsepower Estimate From Trap Speed Calculator

Do you have a high performance car, motorcycle, truck or vehicle, built a new engine, performed a tune up or installed a performance part? Try out this calculator get a rough estimate of horsepower.

This calculator computes the estimated engine or motor horsepower from trap speed. Trap speed is the velocity or speed of a vehicle at the end of a run or race competition. This web app uses the quarter mile distance or track.

Note: This is a rough and quick estimate of engine horsepower. It should be used for recreational use only. To get more accurate measurement of power rating, the engine should be placed under load using a dynamometer or dyno. This will give peak horsepower and torque.

Note: The equation or formula for the calculation uses standard or US units. When using SI units, the units are converted to standard units before the solution is computed.

Note: This application uses HTML5. It should work on all devices (smart phone, tablet, desktop, laptop, hybrids) and operating systems. If any bugs or issues are found, email the author using the address below.
