Listening to the Voice of the Customer: Inertia Dyno Horsepower Versus OEM Rated Net Horsepower 2002-01-0887
The 1990's have witnessed widespread proliferation of inexpensive, inertia-loaded chassis dynamometers. Previously, chassis dynos were not accessible to the general public. Thanks to this proliferation, there is now a core audience of knowledgeable auto enthusiasts who have chassis dyno results for their cars, but little understanding of the difference between these results, SAE net HP and actual power delivered to ground. This audience consists of trend leaders and early adopters, the customers most sought after by the OEMs. This paper derives the loss sources present in these tests, and illustrates the difference between the different reference frames for power measurement.
