LK Motors’ management has never been afraid of the potential for ridicule; which typically afflicts those who think outside the square. In turn, following like sheep is not and will never be our way, nor do we accept what is common policy for others as being absolute. Instead we always adopt a strategy or employ products that we believe better serves the needs of our customers. As a service provider we must offer the best possible service, dictating that we the use of the best possible product, procedure and equipment.
So how do we differ when it comes to dyno tuning? Well, rather than adopting what has become an industry standard in dynamometers – the ‘chassis dyno’ or ‘rolling road’ (the policy beautifully manipulated by good marketing and man’s inherent laziness), we at LK Motors decided to run with a much more accurate device.
Unlike conventional ‘Rolling Road’ Dyno’s whereby a vehicle is strapped to a dyno bed with the front, rear or all wheels (make and model dependent) mounted over a set of ‘driven’ rollers to provide a derived power and torque result, we chose to equip our facility with a significantly more expensive and statistically more accurate type of dynamometer – the Dynapack hub dyno. The hub system works very differently in that the driven wheels (once again be it front, rear or all four) are removed from a vehicle and the axle mounted directly to the dyno hub.
This method ensures absolute repeatability and virtually no variables such as those encountered with a chassis dyno. There can be no tyre slip, no rolling resistance, and no chance of the vehicle coming off of the dyno at high speeds. Tyre temperature, pressure, and traction are all variables that can change – not only from run to run, but during the run as well.
Throw an unknown variable like this into the equation and the data has now become subject to a potentially high margin of error. There are other associated problems with the roller method as well such as tie-down straps with most roller dyno’s using ratcheting tie-down straps to hold the vehicle in position while testing. If the straps are tied down tightly, the tyre has become loaded even further, in an unpredictable manner.
Admittedly, mounting a vehicle to a hub dyno takes more time (hence our earlier reference to laziness), however power delivery is absolute hence the most accurate results which means that we have a vastly better understanding of the results of each tuning change. With variables it can be impossible from one run to the next to actually know whether you have improved the tune or not.
We use the best possible tuning tools, and with the Dynapack, we can honestly state that we have the best measuring equipment, which only goes to ensuring our customer achieves the best result.
