Some information on the Heisel Motorsport dynamometer: This facility is also used by the German Mercedes-Benz Tuner Carlsson. Carlsson has their own engine test-bed, and the data used for correction by Heisel are more than 99% correct compared to the test bed. The results from the Heisel dyno can therefore be regarded as the most accurate approach of determining engine power without explanting the engine and testing it on a test bed. Measurements are taken in fifth gear to get a longer, more expressive graph.
