    Questions & Answers:

    Question 1.)So, how accurate is this dyno then ?

 

    It is incredibly accurate and consistent.
    It is simply the closest thing one is ever going to get without using an Engine Dyno.

    So far, we have performed well over 9,000 dyno runs (in words: nine-thousand !) and from
    those
which we could directly compare against engine dyno data of the exact same engine
   
we have never been out by more than 1,5% which in any book is a most respectable figure.
    (1,5% difference on a 200hp engine for example means 3hp
- this would be the absolute difference,    

    not the difference between runs.  The difference between runs is far less)

 

    A picture says more than a 1000 words, below are two pictures (dyno graphs)

    see for yourself how consistent and accurate we can testÖ

      BMW 740 4,0l: we get the exact graph which the manufacturer specifies
      & just look yet again at the consistency of two consecutive runs on our Rolling Road

 

 

 

    Question 2.)So, how much Power can you put down before the wheels spin ?

 

    Good question..well, we donít really know..to the present day we have never had
    a car powerful enough to wheel spin on this dyno nor a car which made our
Rolling Road
    run out of steam, and we truly have had some big ones down here..on one occasion we
    had an impressive 1180 lbft at the wheels
    (in words: one-thousand-and-one-hundred-and-eighty-lbft) on the dyno and still no wheel spin.
    The featured cars so far
have been childsplay for our Rolling Road, that's for sure.

 

    The Rolling Roadís manufacturer ratings are:

    200mph constant, 880 hp at the wheels mapping,

    1200 hp power testing and 4100 Nm torque (3020 lbft)

 

 

    Question 3.)My car is very low..what is the lowest car you can test without taking the spoilers off ?

     As we have no Roller Lift the car does not sink down once on the rollers, so therefore any car that
     can drive on the road or track, be it as low as it may can be tested without any mods on our   
   
 Rolling Road.

 

 

     Question 4.)So, how on earth does it work?

     How come the car does not come off when balancing on these rollers, surely that canít work(or can it ?)

    We use a specially formulated fixing compound to hold the car securely in place.
    It is based on an old recipe formulated by the old Druids which can only be harvested during
    a full moon and
it is a solution consisting of ... <classified top secret information>

 

    ..seriously: due to the geometrie of the strapping, the vehicle under test becomes locked in a very stable position from which it is not able to    
    move...over 9,000 dyno runs have proven this to us beyond doubt.
