Before your engine is installed in a vehicle we can verify the performance and emissions in our engine test cells that are equipped with high speed 1000 PS dynamometers.  Our engineers can help with calibration issues to find the best map for your application.  We can focus on efficiency, power, torque or emissions.

We can also access hofer test cells in Germany that offer a wider torque range to support small through to heavy duty engine development.
