The AutoDyn™ 849 two-wheel-drive chassis dyno is unrivaled in the marketplace. Its dual eddy current absorbers provide 1,600 horsepower of loaded absorption capability and its large 42” diameter rolls create one of the largest contact patches available to the market. This large contact patch and precision knurled surface generate superior traction while causing the lease amount of tire deflection so testing is as close to real world conditions as possible and no tire damage occurs. These features make the AutoDyn™ 849 chassis dynamometer perfect for anyone who is serious about tuning high horsepower and high torque vehicles. Thanks to its unique design, the SF-849 chassis dyno generates unmatched low end torque to easily load and spool the turbos found on many performance diesel trucks. Couple that with the high speed horsepower capacity to handle turbocharged, supercharged and nitrous equipped two wheel drive cars, the SF-849 is the most versatile two wheel drive chassis dyno on the market.

The AutoDyn™ 849’s dual eddy current absorbers lets you perform loaded testing to make EFI tuning simple and fast. The absorbers are coupled directly to the rolls through a heavy-duty differential for the most accurate testing possible. The included WinDyn® Dynamometer Software makes it easy to test at varying rates of acceleration, deceleration, steady speeds, and part or full throttle through multiple gears. You can simulate circle track, road course, and high-performance street applications or use SuperFlow® Road Simulation Technology (RST) to reproduce real-world driving conditions. SuperFlow® (RST) accurately loads vehicles according to their inertia, aerodynamic losses and rolling losses so you know that when you get to the track your vehicle will perform just like it did on the dyno.

The AutoDyn™ 849 is also easily upgradeable to AWD if your testing needs were to change down the road. With the addition of a second roll set and a driveshaft to synchronize the front and rear rolls, the SF-849 quickly and affordably becomes a SuperFlow AWD chassis dynamometer. This grants you the peace of mind to know that you can start with a top of the line 2WD dynamometer and easily turn it into the best AWD chassis dynamometer on the market when the time is right for you.
