The ET Method used by this Engine Horsepower Calculator uses the weight of your motor vehicle along with the time taken to finish quarter mile or 402.3 meters. The formula of horsepower in this method is:
Engine Horsepower = Weight / (ET/5.825)3
Weight of your motor vehicle. Input the weight in Pound, Ton, or Kilogram.
Keep the time to see how long it takes to finish a quarter mile or 402.3 meters. Specify the time elapsed in second, minute, hour, or day.
In this method, you will require to find the weight of the vehicle and the speed of your vehicle when finishing a quarter mile. The formula to calculate horsepower under this method is:
Engine Horsepower = Weight x (Speed/234)3
Speed of your vehicle at the time of crossing a quarter mile or 402.3 meters. Based on your speedometer, choose the speed at miles per hour, kilometers per hour, or meters per second.
The calculated engine horsepower defines how well your motor vehicle will perform. The more the horsepower and less the weight, the better your car will perform. It is simply a power to weight ratio that distinguishes high-performance cars from low-performance cars.
