4wd – BPA-4R HP

The HP series is the Bapro’s highest performance chassis dynamometer. A couple of belted 400 mm diameter rollers, the best guarantee for the utmost in repeatability and accuracy. With a massive tubular frame made by high strenght steel, this High Performance series suites all needs: Testing, R&D, Motorsport, Tuning and Chip Tuning. BPA-4R High Performance is suitable for every kind of power and torque.
Axles synchronization: Electronic linked and synchronized axles via software, made by fast and precise high frequency control of eddy current brakes to synchronize the axles in a 4wd car (Bapro’s patented system). This to avoid differentials damage and to be more precise in tests because power wasted in slippage inside the differentials is avoided too. Thanks also to this, BPA-4R HP dyno is extremely easy to be installed and the maintenance is almost absent.
