Eddy-Current Chassis Dynamometer Information

To get the most horsepower and performance out of your engine, AF1 Racing utilizes the latest in dynamometer technology. We exclusively use the Factory Pro EC997a eddy-current low-inertia dynamometer. An eddy-current style of dynamometer is far superior to an inertia-style dynamometer (most DynoJet dynes) in terms of its accuracy and capabilities. An inertia-style dyno is a glorified accelerometer, while an eddy-current dynamometer provides real-world loading of the engine. Only a true eddy-current style of dynamometer is capable of step-tests, where the eddy-current brake holds the engine at specific RPM data points and measures HP and torque in real-time steady-state. Testing steady-state, where drum acceleration equals zero, is the only way to get accurate EGA data, True horsepower readings, and real-world loading. Having the capability to tune steady-state is the only way to accurately tune EFI-equipped motorcycles and flatslide carburetors.

HP = (Torque x RPM) / 5252 and Torque = (HP x 5252) / RPM

An inertia style dynamometer measures HP and torque by calculating the acceleration of a heavy drum during a rapid sweep test. You cannot hold steady-state on an inertia dynamometer (accelerometer) making EFI and flatslide tuning impossible at best. How does one test highway cruise and part throttle when you have to accelerate the drum just to get a reading? An eddy-current dynamometer measures rear wheel torque with a load cell while the engine is loaded steady-state at any specific RPM we choose. Think of it like a giant torque wrench where the brake provides resistance against the force of the tire. After measuring torque with the load cell on an eddy-current dynamometer, calculating HP is easy. Horsepower is a simple function of torque and RPM.

Our dynamometer also features a super light roller that is quick to react to load changes and power outputs, which enables us to very precisely tune EFI-equipped bikes, and flatslide carburetors. Our Factory Pro eddy-current dynamometer is not affected by gearing changes, wheel inertia changes, tires sizes, or tire pressures. It reads True HP corrected to SAE atmospheric conditions. It is 0.2 HP accurate every single day, every single run ever done at any Factory Pro tuning center. We can accurately compare any two sessions any Factory Pro dynamometer has ever done. No other machine comes close to its repeatability and accuracy. Expect your HP numbers to be around 12-17% lower with our dynamometer when compared to inertia-type dynes commonly used in magazines and at other shops. Our machine can run anything from scooters, cruisers, HDs, dirtbikes with knobbies, two strokes, and AMA Superbikes.

Diagnostic Dynamometer Session with 4-gas EGA

  • Full throttle step tests done at specific RPM increments to measure true maximum HP and Torque steady state with 4-gas EGA.
  • Diagnostic steady-state step tests at various 75%, 50%, 25%, and 10% throttle openings and at various RPM data points with 4-gas EGA. These tests simulate real-world medium to light engine loads, part throttle cruise, and off-idle responses.
  • Idle mixture analysis with 4-gas EGA. Test will show how to improve idle quality
  • Printouts of data. All your data is archived with us for comparison to future runs.
  • Interpretation of the results and suggestions for improvement

The 4-gas EGA measures %CO, %CO2, HC (ppm), and %O2. Using a 4-gas EGA and not a Lambda (A/F) sensor is the most accurate way of collecting exhaust gas data. We have the only dynamometer in Central Texas that can do this.
