How much horsepower does a 163 cc engine equal?

To determine the horsepower equivalent of a 163 cc engine, we can use the following formula:

Horsepower = (Engine Displacement in Cubic Inches) * (RPM) / 2500

First, we need to convert the engine displacement from cubic centimeters (cc) to cubic inches (cu in):

163 cc / 16.387 cc/cu in = 9.96 cu in

Assuming a typical maximum RPM (revolutions per minute) of 8000 for a small engine of this size, we can calculate the horsepower:

Horsepower = (9.96 cu in) * (8000 RPM) / 2500

Horsepower ≈ 3.19

Therefore, a 163 cc engine is approximately equivalent to 3.19 horsepower.
