Inertia Dynamometer Advantages
|Inertia dynamometers are extremely accurate when operated and designed properly. A proper inertia dyno requires NO calibration of ANY kind no matter what kind of vehicle you are using. If someone is calibrating an inertial dyno, they are screwing with the very thing that makes an inertial dyno worthwhile - consistency. The fact that they do not require calibration rules out a lot of margin for error.|
One of the main advantages of an inertial style dyno is its unmatched ability to conduct back to back testing. When testing part A against part B for overall horsepower difference - inertial is the way to go, as it is more accurate than a hydraulic dyno for measuring actual horsepower consistently. There are less moving parts, and the concept is extremely simple.
