WebApr 1, 2024 · An inertia dyno calculates engine power output by measuring the time it takes for the car’s drive wheels to accelerate a heavy steel drum. Force at the surface of the drum is measured indirectly by measuring its acceleration from one revolution to the next. Force is calculated using Newton’s 2nd law, Force = Mass x Acceleration. WebFeb 21, 2024 · Measuring Horsepower With A Dyno There are two main types of dyno; an engine dyno and a chassis dyno. Carmakers will usually use an engine dyno which measures the amount of power and torque the engine makes at the crankshaft. Then they use the result of this test to put in their brochures.
