Dyno Testing Image

Dyno Testing

Here at Prestige Motorsports, our “Dyno Promise” means that we dyno test every engine we build to verify the quality of our work, the integrity of each component, and the reliability of every engine we construct. Then, we deliver the dyno results for your project directly to you, the customer.

Engines will produce +/- 2% of advertised power at the flywheel. Advertised power levels are achieved using an electric water pump and specific induction and exhaust systems. Power will vary after pulley systems are installed or if changes are made to the induction or exhaust system (e.g. camshaft, cylinder head, compression, intake manifold, exhaust headers, air filters, etc.). Chassis dyno results measure power at the wheels and only calculate flywheel horsepower. Wheel horsepower is affected by a variety of vehicle-specific criteria including driveline design, body and chassis flex, air intake location, etc. Therefore, calculating flywheel horsepower from wheel horsepower is not an accurate representation of actual flywheel horsepower.
