How does it work? Well, basically the Road Dyno System is a precision timing system that looks at a record of engine RPM over time. Based on when a single spark plug fires, the program can compute acceleration, and therefore, power. The user must supply the car's weight, gear ratios, tire sizes, and some other variables, but the rest is pure physics. This is not a power estimating program! The Road Dyno System measures the power of your engine directly by making precise measurements. Road Dyno System measures power by the same method as a chassis dyno. Instead of measuring the amount of power required to accelerate a drum, you are measuring the amount of power required to accelerate the car. This is really what you are interested in anyway isn't it?

Some cars may even perform differently on a chassis dyno because the car is not actually moving. Accelerating the car has an effect on fuel in the bowl of the carburetor (if you happen to have one of those), oil distribution through the engine, air resistance, turbo airflow etc, etc. The Road Dyno System will allow you to accurately measure the amount of power your car is putting to the ground, which is an invaluable tool when doing aftermarket modifications. The Road Dyno System takes hundreds of power measurements through the entire power band of the engine being tested. This provides enough resolution to be able to analyze performance parameters like spark advance, knock retard, power drops as a result of fuel pressure, etc.
