Rolling Road

Rolling Road

Our sun Rolling Road is current state-of-the-art equipment which can give very accurate readings of speed, torque, horsepower and transmission loss.

How does it work?

The car is run through the useable rev range at full throttle and the machine prints out a chart of torque and brake horsepower. Subsequent changes to such things as ignition timing, exhaust system, camshaft etc. can be re-tested and compared with the original readings on the same graph. To keep the engine cool we have an industrial cooling fan that is placed in front of the car and acts as the "cooling wind" you would expect to find when driving.

Other benifits.

Speed readings can be used to check speedometers also power loss figures for comparison of transmission changes. All readings are automatically corrected for temperature and atmospheric pressure.

What the customers think.
