How to Choose an Engine Dynamometer What are you testing -- engines directly out of the vehicle or the complete vehicle? If the answer is vehicles: Are you testing cars, motorcycles, trucks, ATVs, go-carts, something else, or a combination of these?. Do you need four-wheel-drive, or will a two-wheel-drive dynamometer work for you? Which axle do you prefer: independent or interconnected?. Do you want only power absorption, or do you need motoring capability? With both engines and vehicles, the dynamometer selection is essentially...
