The only dyno line that expands with your needs. Start today with a low-cost inertia-only model. Later mount an absorber, expand to AWD, add channels, upgrade software, etc. – without wasting your original investment. Excluding roll diameter (see below) most feature decisions may be revisited – years later. We manufacturer all major components in house – saving you third-party markups of competitors.
• Only doing speedometer calibration, or part-throttle OBD-II checks? Then tiny 8½" Garage Class roll diameters may be okay.
• Tuning 300+ Hp drag/street/rally cars? Get serious with larger-diameter Tuner Class rolls.
• Developing high-speed hyper cars, or performing research work? Demand 36" (or larger) R&D Class diameters.

*Approximate; limited primarily by tire safety and traction - higher torque transfer requires tie downs. Continuous capacities depend on selected absorber and test speed. Air-cooled absorber loads are rotor temperature dependent. Water brake power capacities are RPM dependent and assume a minimum water supply of 1 gpm @ 30 to 60 psi for every 20 continuous Hp.
