How is motor horsepower calculated?


Answer by  Iamstrong (659)

A specific formula is required to calculate motor horsepower. The formula is most commonly used is "speed" at the conclusion of a quarter mile run. Additionally, weight of vehicle, passenger(s), and driver should be considered. A sample formula is denoted as follows" Horsepower= weight x[velocity]3 [ 234 ]

A motor is put onto a dyno where it is run through a make-shift transmission. When spinning this transmission a computer hooked to it will tell you how much force is required to turn it aka Horsepower/Torque. If it hasnt been on a dyno its just a guess.


Answer by  twitchard (143)

Simply put the amount of force the motor can generate (determined by speed of pistion output. This multiplied by the distance the engine can travel while generating that force. This end number is then divided by the time it takes to reach a certain point. This is the equivalent equation for horsepower.


Answer by  PuterGuru (256)

You can calculate horsepower by using a weight, distance and time calculation. Weight / (Elapsed Time * 5.825) to the third power.

To measure the horsepower put the motor on dynamometer. Then engine is ran and machine takes measurement on how much energy is being used. These measurement are then turned in to horsepower and torque.


Answer by  Amber40 (24961)

To measure the horsepower output of an engine it is placed on a dynamometer. Then the engine is ran and the machine takes measurements on how much energy is being used and how fast it is being used. These measurement are then tuned into units of horsepower and torque.
