There’s probably nobody better known in the engine dyno field than SuperFlow, but no matter how useful an engine dyno is for getting a motor dialed in before it goes into a car, there’s no substitute for the “rolling road” when it comes to putting all the elements of engine and drivetrain together to ultimately get that power to the pavement. It should come as no surprise then that the wizards at SuperFlow also make some very good chassis dyno models as well.
The AutoDyn 30 AWD shown here is a perfect example. It uses SuperFlow Road Simulation Technology to mechanically synchronize the front and rear roll speeds and accurately load each wheel via race-inspired differentials and a steel driveshaft that connect the rollers. An eddy current brake, controlled by SuperFlow’s WinDyn software, can apply load to accurately simulate inertia, aerodynamic losses, and rolling losses. The system is designed to eliminate problems caused by unsynchronized rollers activating traction control systems or ABS, and prevents damage to center differentials or viscous couplings in AWD cars.
The large, 30-inch diameter rolls provide added traction and minimal tire deflection, and the wheelbase adjusts with a push of a button over a range of 40 inches to accommodate practically all AWD vehicles on the road today.
The included Sensor Box monitors environmental conditions, manages the eddy current brake, and measures data from the AutoDyn – the real-time weather station built in continuously updates the correction factors for the best possible accuracy and repeatability.
You might expect all these features to be difficult to manage, but SuperFlow has made it easy with their wireless, touch-screen NetDyn netbook, that allows the dyno operator to control and monitor the AutoDyn’s operation from the driver’s seat, while simultaneously running tuning software if desired.
