Our company use and develop software on the dyno Dynocom 15.000 series with DC PAU Eddy Brake from United States.
Possible test: car, motorcycle and truck (maximum axle weight is 6350kg and the track width range is 76cm-260cm)
The 15,000 series is capable of supporting speeds up to 384kmh and 2400+ HP. The maximum axle weight is 6350kg and the track width range is 76cm-260cm. The 15,000 series chassis dyno’s are also upgradeable for the DC-PAU-750 center-mounted eddy brake for steady state testing, which can support an additional 850+ HP. 
For high torque applications such as diesel testing or high horsepower drag cars, the DC-PAU-750 offers the world’s largest eddy brake capable of support over 3000 ft lbs of torque. 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.
This newly redesigned dyno incorporates a stainless steel wrapped around a massive welded hybrid-pyramid frame. This revolutionary new frame design has form and function and allows for better braking and smoother operation. The 15,000 Series comes standard with our X Factor Knurling option which provides the highest traction over all other competitors. 
The optional eddy brake assembly sits directly on the shaft between the two rolls - no need to couple with a belt or universal joint all power is directly transferred from the wheels to the load cell.
