Our mustang chassis dynamometer is installed with the latest state of the art "Powerdyne" software which enables us to measure horse-power, torque, air to fuel ratio, oil temperature and turbo boost.

The installation is above ground and your car is driven on to the ramp and lifted to the dynamometer. As you would expect from an American road, it is big and can accommodate large American cars and pick ups effortlessly.

This data enables us or your tuner to tune or develop your car. If you wish to hire the rolling road for your tuner, we will provide an operator only.

There are a number of test modes including power, vehicle simulation, constant load and quarter mile drag. Please contact us to discuss what is most appropriate for your car.

The large diameter 50" drums give very good traction and power transfer to wheels. Tyre wear is minimised and drivers consider tyres to be race-ready once they have been run in on the dyno.

 

With a 50" diameter roll set, a maximum speed of 250 mph,
and a horse-power measurement rating of 2,000 hp, the MD-1750 is by far the fastest and most powerful dynamometer available in its class. The twin eddy current power absorption feature allows for "steady state" testing at various speeds and torque outputs, making the MD-1750 a dynamometer in the truest sense.

The MD-1750's inertial based testing capability provides a
practical and efficient means to gauge vehicle performance.
Inertial based performance testing involves accelerating a
cylindrical mass with a known inertia at wide-open throttle.
In the case of the MD-1750, the immutable inertia encased in a 50" diameter roll, or drum, acts as the road-load mechanism. The rate at which the vehicle is able to accelerate the drum provides insight into the amount of energy transferred from the tyres to the surface of the drum. Speed and torque combined produce instantaneous wheel horse-power data. These data are then plotted against time, speed, or distance to produce easy-to-use graphs. A database keeps track of testing records for future baseline test comparisons.

The dual eddy current power absorption unit enables the system to test vehicles at variable throttle-positions, speeds and torque outputs. The torque value read from the load cell is combined with roll-speed picked up magnetically at the roll shaft to calculate the exact force being applied at the vehicle's wheels at any time through absorbers. An advanced closed-loop computer control system enables the user to carefully control the road load applied to the vehicle under test by increments of horsepower or torque.
