A 4WD dyno that has hardly no limit...
This is the most powerfull dyno we produce at the moment.
The Dynostar Model W4X is the icing on the cake from the Dynostar range of dynamometers. The adjustable wheelbase from 2 meters up to 3.5 meters makes this dynamometer suitable for testing almost every type of car.
The dynamometer is fitted with two air-cooled retarders, in total 4900 Nm, which results in a maximum absorbed power of 1000 kW for brief periods and over 350 kW continuous. To guarantee optimum grip, the dynamometer rollers are optionally treated with tungsten carbide as an anti-slip coating. The Dynostar Model W4X works on the rolling road principle. The front and rear rollers are synchronised by means of an impressive drive line. Thanks to this construction, even two-wheel drive vehicles fitted with ABS, ESP or ASR can easily be tested.
The Dynostar Model W4X has an extensive list of options in both features and accessories. It is also possible to have an 'above ground' version.
For professional users, Dynostar offers the option of fitting this dynamometer with an up to 75kW electric motor and inverter (frequency controller) to simulate the drive cycle. In addition, the dynamometer can also be fitted with a second load cell so separate power measurements can be performed on the front and rear axles. To control this type of dynamometer, the familiar DAS Data Acquisition System is used in combination with a PLC system. All controlled by the Advanced Dyno Station software package. The software for the Dynostar Model W4X also has a number of interesting add-on modules such as the “drive cycle and drive simulation”. Using this feature, the drive cycle can be simulated optimally. The rolling period can be set vehicle-dependent for optimum simulation of the drive cycle.
