Portable ProHub 2WD Chassis Dynamometers

The Mainline DynoLog Portable ProHub 2WD Chassis Dynamometers are the ultimate tuning solution for ultra-performance vehicle applications. Designed for testing extreme streetcar and drag cars, the ProHub Portable Chassis Dynamometers bridge the gap between an engine dynamometer and a roller-based chassis dynamometer.

ProHub Portable (2WD Axle Shaft)

The Portable ProHub Chassis Dyno system provides an effective “in chassis” tuning solution, without the need to remove the engine, or to hire a drag strip facility. Both these tuning options require a significant amount of time, money, and effort to be able to achieve practical results. In some cases, even an engine dynamometer cannot cope with the power and torque levels produced by such engines, and a traditional roller-based chassis dyno, which relies on the tyre to roller interface (traction), is simply out of the question. 

The Portable ProHub Chassis Dynamometers are available in 2000hp or 3000hp models, are quick to setup, easy to move around your shop, or can be stored away when not in use. The Portable ProHub models can also be upgraded to a ProHub AWD model if ever required after initial sale.

The Portable ProHub 2WD Dynamometer connects directly to the vehicle's axle hubs, via billet steel adaptors, effectively removing wheel and tyre related variables from the testing and tuning equation, for absolute accuracy, and the ultimate in test data repeatability from power run to power run.

All 2WD Portable ProHub models are maximum speed rated up to 3600 axle rpm or equivalent road speeds of up to 310 mph (500 kmph) subject to vehicle gearing. The “Power Absorption Modules” (PAMS) on the 2000hp & 3000hp models have integrated wheel assemblies allowing them to be easily moved to the vehicle, correctly aligned, and quickly connected to the vehicle’s axle hubs.

After testing is completed, the PAMS can be rolled away and stored when not in use.

The Power Absorption Modules” (PAMS) are a " noncoaxial " type design. The modules sit flat on the floor, and you do not have to adjust the angle of the modules to match the camber of the vehicle. This means a much quicker setup when compared to most of our competitors who utilize a coaxial-type design.

It is not critical what angle the modules are attached to the car ( vertically or laterally). Our early ProHub Dynamometers product research identified in some scenarios, if the vehicle’s axle and the retarder/ absorber centre line are aligned (coaxial) there can be vehicle harmonics/vibrations that occur.

We use a twin CV joint system contained within the extension tubes of our modules,  and we offset the retarder position inside the modules slightly to ensure the connection to the vehicle can never be coaxial.

Portable ProHub dynamometers will accommodate up to +/- 10 °camber and 10 ° toe in /out, to accommodate live axle and IRS systems.

Applications for the ProHub dynamometers include performance tuning, ignition timing perfection, pre-race testing, driveline torque testing, clutch evaluation, stall convertor mapping, multiple stage nitrous injection testing, and performance product research and development.

The ProHub Chassis Dynamometer can also be setup as a very cost-effective engine testing solution, in comparison to setting up a complete engine dynamometer facility.
