Dynostar M70


The Dynostar Model 70M is a mobile roller chassis dynamometer with an eddy current brake which can be used anywhere for tuning or diagnostic work. The dynamometer is fitted with a special frame which is suitable for using it on the public road. The Dynostar Model 70M weighs around 1170 Kg, is fitted with a run-up brake and can be towed by a car.

The Dynostar Model 70M is technically identical to the Dynostar Model 70. The dynamometer is fitted with a high rigidity frame. As a result, the dynamometer is totally free from vibrations, which makes this model a very reliable dynamometer.

The Dynostar Model 70M is equipped with a roller with high mass inertia, and can absorb dynamic power up to 465 kW and speeds up to 325 km/h. A powerful, air-cooled eddy current brake allows the dynamometer to absorb power up to 355 kW (with cold eddy current brake). We can guarantee you optimum grip because the rollers are grooved as standard and optionally treated with tungsten carbide.
