How do I find out my horsepower?
The equation to calculate horsepower is simple: Horsepower = Torque x RPM / 5,252.

How do manufacturers measure horsepower?
So, how exactly does one measure torque and horsepower? Well, engineers use a device called a dynamometer, of which there are a couple of types. This dynamometer, called a chassis dynamometer, is a treadmill of sorts for cars.
What is the value of 1 horsepower?
The horsepower (hp) is a unit in the foot-pound-second ( fps ) or English system, sometimes used to express the rate at which mechanical energy is expended. It was originally defined as 550 foot-pounds per second (ft-lb/s). A power level of 1 hp is approximately equivalent to 746 watt s (W) or 0.746 kilowatt s (kW).
How much HP do you lose from engine to wheels?
Broadly, 15 per cent of the engine’s peak power is lost to friction, getting to to the wheels from the crank. So 300 kilowatts/horsepower (whatever) at the crank is about 250 at the wheels (ballpark estimate).
How BHP is calculated for an engine?
BHP is measured by applying a resistance torque as a brake on the Shaft . A ) BHP = (2πnT ) /33000 ,2πnT = Power in lb-ft per min. n =no. of revolution per minute of the engine , T = Torque applied on shaft.

Is a big block faster than a small block?
In each cylinder of an engine is a piston, and the distance that piston has to travel up and down is referred to as “stroke.” Small stroke equals small block, long strokes equal big blocks. Typically long strokes result in more torque while short strokes make quicker revving possible.
