Tuning with the Dynapack Hub Dyno
Superior accuracy to a traditional rolling road…
At Lloyd Specialist Developments we use a state of the art Dynapack chassis dynamometer at our workshop in Wiltshire in the south-west of England.
The Dynapack dyno is a hub dyno. A conventional rolling road is subject to inaccuracies due to variations in tyre pressure, tyre temperature, tyre traction, rolling resistance, etc.
Even something as simple as the ratchet strap tension on a conventional rolling road will cause inconsistent results, both between and during runs. The Dynapack hub dyno eliminates these variables by using hub adaptors to directly couple the hubs to the power absorption units so there is no tyre / roller interface whatsoever.
Directly bolting to the hubs is also a much safer method of dynamometer testing your vehicle, with no chance of your car coming off the dyno – due to the wheels climbing out of the rollers or suffering from a tyre blow-out!
This also makes the hub dyno a more popular choice with owners of particularly powerful cars – e.g.: turbocharged, supercharged and V8, V10 or V12 engines. 4×4 vehicles or competition off-road vehicles are also more prone to climbing out of the rollers on a conventional rolling road. This is due to the larger diameter wheels and tyres being less compatible with the smaller diameter rollers. Again, no problem with our Dynapack hub dyno!
A chassis dynamometer is an excellent tool for tuning, engine management mapping, diagnostics and remaps. Our particular dyno can be used with both 2WD (two wheel drive) or 4WD (four wheel drive) vehicles.
