VT-4 Modular Dynamometer

Two axle dyno, designed for cars with one or two driven axles. It allows for the measurement of power and torque in the inertial mode.

The dyno is normally equipped with a mechanical system of axle synchronisation, enabling the measurement of the most modern cars, with an active central differential or with advanced traction control. A possibility a of further upgrade to the braked version. The dyno is offered in a standalone version or pit version.

[1] Mechanical connection between front and rear axles (synchronization) gives you an opportunity to measure modern AWD cars equipped with high tech systems controlling torque distribution between front and rear wheels, also 2WD cars equipped with advanced traction control system in which all the wheels must rotate in equal speed (otherwise car ECU will not be able to measure the car).
