How's Horsepower Calculated

Calculate Torque


Good buy elsewhere the torque of your engine. You'll devoir access to a dynamometer or "dyno" for short. Torque Testament be relative to the rate at which your engine is spinning. For instance, if your torque is Three hundred pound-feet, there will be an associated revolutions per minute, or "RPM," associated with your torque number. So, For instance, your engine may be producing Three hundred pound-feet of torque at 4,000 RPM.So, using this example, you'll need to multiply Three hundred x 4,000 = 1,200,000.


Multiply Torque by Engine Speed


Multiply the torque numeral by the engine velocity. You should get both of these numbers prone to you by the dyno technician. Exclusive a able dynamometer technician can guide these. Usually, this involves locating and scheduling an appointment with a shop or garage that has a dyno in-house. Your vehicle is levy on a Apartment lodgings Bedstead with a rotating shove underneath your vehicle's handle wheels. As you accelerate the vehicle on the dyno, your vehicle remains stationary and the dyno spin spins, measuring the endowment output and torque of your vehicle. Once the technician has calculated the torque for your vehicle, assemble sign of this figure.



Divide by 5,252


Divide by 5,252. This number is derived from a series of conversion factors which are added together into this one number.


Continuing the example above, the equation would look like this:


(300 x 4,000) / 5,252 = 228.48


You can round this number off. So, For instance, instead of using 228.48, you could round it off to 228. This number represents horsepower.
