One of the most common ways of measuring a diesel truck’s horsepower and torque is running it on a chassis dynamometer, known as a dyno, for short. Perhaps the simplest type of dyno is an inertia dyno ...

What's the real-world difference between running an engine on an engine-dyno, or, as installed in the car, on a chassis-dyno? Recently, we were able to conduct an engine dyno versus chassis dyno ...

Maybe I'm ignorant for having this mindset, but I always thought you could go to a dyno to figure out how much power your car makes and that was the number you could proudly tape to your fridge. Jason ...

We may have goofed, but we're man enough to admit it. Despite the countless engine dynamometer tests car magazines publish each month, we've rarely-if ever-explained how an engine dyno actually works.

Dynamometers are used all the time to measure power output for cars. The standard estimate for comparing wheel horsepower (the number retrieved from the dyno) to crank horsepower (the manufacturer's ...
