ROTOTEST DYNO INFORMATION PAGE

TDI are the appointed UK demonstration centre for the Rototest VPA-R dyno system.

In keeping with our reputation for leading the way when it comes to vehicle tuning, we have just taken delivery of our most expensive piece of hardware to date; the Rototest VPA. This incredibly costly setup was the only solution for us in terms of repeatable accuracy and will enable us to continue our research well into the future.

1. In line with the TDi culture of pioneering, we have had a dyno on our premises from day one, and TDi was
the first tuning company in the UK to have a 4 wheel drive dyno.

2. TDi are the first tuning company in the UK to offer a dyno service to the general public using scientific quality equipment, which until now has been the sole reserve of major manufacturers and esteemed race teams.

3. The Rototest is currently among the most expensive dyno currently available although we would have quite happily bought a cheaper alternative if we considered it to be good enough for our purposes. Rototest is the choice of major institutions such as Cosworth, Shell, Opel, Mercedez Benz, Chrysler etc. 

4. Rototest is the only hub mounted chassis dyno that actually measures torque, as opposed to calculating (or guessing) figures. For this reason, the Rototest is also the only hub mounted dyno that can be acurately calibrated.

5. Rototest invented the hub mounted dyno and held the patent for this design. Being directly bolted to the hubs completely eradicates the problem of tyre slip and the associated errors found with 'rolling' roads using either single or twin rollers.

6. The Rototest dyno has superior control over any other type of dyno that we have seen. Not only is it able to vary the load by extremely small increments at any rpm, it can also hold the vehicle at any rpm set by the operator regardless of throttle position. This allows the operator to concentrate purely on the task in hand rather than struggling to hold the vehicle at X rpm himself and means that we are able to very accurately map and tune cars to the degree that no other dyno allows.

7. The Rototest Data Aquisition Centre is without doubt the most sophisticated and comprehensive available anywhere. This allows us to monitor all aspects of the engine dynamics which again allows us to be very accurate in our tuning and mapping. 

8. Finally, it is worth mentioning that whereas there are several dyno's that have been bought recently by competitors, many have little or no previous experience with using them. TDi have had a dyno since the company was formed in 1985 and so have considerably more dyno experience than any other tuner in the UK.
