Rolling-road testing: Power rangers

摘要

While perhaps subject to some variations, a rolling-road test can provide useful information about the performance and health of your engine. REGULAR READERS will know that we frequently refer to the use of rolling roads when reporting on the power outputs achieved with various performance conversions. Indeed, the rolling-road dynamometer has become an essential workshop tool for many tuning companies. It enables them to undertake extensive testing and development work in a controlled environment, and it provides proof of the benefits by measuring the engine's performance before and after a conversion has been carried out.
