Rotor Tube Comparison

Now the real comparison – The left “brake drum” is a 1957 design which is still included in production as of today.

The “Rotor Tube” on the right is the 21st Century Patent Pending design in the Power Torque Series dynamometers produced by Dyno Tech Services.

Again, which would you rather be testing 800 horsepower and 4300 ft/lbs of torque with?
