SuperFlow manufactures water brake, eddy current and AC engine dynamometers for performance and industrial applications. SuperFlow engine dynos test gasoline, diesel and CNG engines and several of our water brake dynos are used for AC motor testing.

We frequently provide custom engineered engine dynamometer solutions for unique test requirements. Our engineering team will understand the application, select the appropriate power absorption unit, design all test cell support systems and configure our WinDyn data acquisition and control system to manage the dyno, the engine and the test environment. If you have a standard or unique engine testing requirement contact us and put our 40 years of engine dyno experience to work in your test cell.
