AutoDyn 880 AWD Chassis Dyno

here is a reason that the AutoDyn™ 880 AWD is used all over the world by some of the most respected names in automotive performance. That reason is simple: SuperFlow® has perfected the art of accurate road simulation via a simple and reliable mechanical linkage. SuperFlow's® Road Simulation Technology(RST) utilizes heavy-duty differentials and a steel drive shaft to synchronize the front and rear roll speeds along with eddy-current brakes to accurately load vehicles according to their inertia, aerodynamic losses and rolling losses. SuperFlow® RST prevents damage to the differentials and viscous couplings of AWD vehicles and removes the chance of activating a vehicles traction control system or ABS while accurately loading each vehicle as if it were traveling down the road or track.

SuperFlow® RST is much simpler and more accurate than complicated belt systems that stretch and break or inconsistent electronically synced systems that allow the front and rear rollers to spin at different speeds, causing driveline windup and damaging driveline components. Differentials and driveshafts allow SuperFlow® to accurately measure and compensate for the parasitic losses of every dyno produced so that each one leaves the factory calibrated with its own inertia and parasitic data. The end result is the most accurate torque and power measurement available. Further, torque is measured using two temperature-compensated load cells, one at each roll set, so you're not only able to see total torque across the rpm range, but also the torque split between the front and rear axles.

The AutoDyn™ 880 AWD's large 42" knurled rolls provide superior traction and minimal tire deflection so testing is as close to real world conditions as possible. Cradle roll systems deflect the tire in two locations which builds more heat in the tire and results in less accurate hp measurement than large single roll dynos like the AutoDyn™ 880 AWD.
