Mechanically linked AWD chassis dynamometer system. The AWD -5000FX front portion of the AWD unit is a 2WD 5000 Series unit and the rear is a set of linked rollers with 36-80 Inch track width Gates Poly Chain® GT2®. The AWD 5000-FX dynamometer is capable of supporting speeds up to 175+ MPH and 2000+ HP. The maximum axle weight is 6,500 lbs and the track width range is 36"-86". The AWD 5000-FX was designed for a variety of different testing scenarios – FWD/RWD Cars, Sport Compacts, Motorcycles and ATV’s. It is equipped with an FRENELSA eddy brake and you are able to perform acceleration, step, sweep and steady-state tests. • View in real-time torque/horsepower output, at steady and changing speeds, to instantly evaluate changes you've made to the engine's fuel or timing maps. • Diagnose engine and drivetrain problems. • Troubleshoot drivability issues. • Run track ¼ mile or circle track lap simulations with reaction times that you determine in the software parameters. The AWD-5000-FX Series dyno incorporates linkage which insures that the front and rear rollers are always spinning at precisely the same road speed. This process eliminates the possibility of activating a vehicle’s traction control system and also insures that a vehicle’s torque management system is operating under the assumption that the vehicle is not skidding, turning or slipping. The AWD 5000-FX can be operated in AWD Mode while testing two-wheel drive vehicles. This process allows the non-driven axle to be spun by the dynamometer rollers at the same speed as the driven axle, eliminating the speed differential that occurs on two-wheel drive dynamometers. The belt linkage system on the AWD 5000-FX dyno has the ability to properly test the most sophisticated vehicles on the road today: Porsche's, Lamborghini's, Nissan GTR's and other modern AWD vehicles with a non 50/50 split.
