Engine Dyno

As of the leading UK engine builders for both classic and classic racing engines, Mass Racing has our own engine dyno facility. An engine dynamometer, or “dyno” for short, is a so[histicated device for measuring force, moment of force (torque), or engine power – calculated by simultaneously measuring torque and rotational speed (rpm).

Mass Racing use en egine dyno to determine the power output of an engine follwing a rebuild or the effects of upgrades.

Contact Mass Racing about your next engine project for your classic vehicle.

Rolling Road

A rolling road is a useful piece of machinery, which Mass Racing use, on which the wheels of a vehicle can roll in order to test how well the vehicle works under simulated road conditions. The car is placed on the rolling and secured with the driving wheels on a roller in the floor, the engine is placed then under load as it drives through the gears – the output of which is measured to determine the engine performance and power output.

The Mass Racing engineers can then use the output graphs of the engine performance for Torque and Horse Power to determine results of upgrades or optimisations required.
