1200 hp TAT Rolling Road
purpose built Dyno cell with our 25" fully computerized TAT Rolling Road
which can monitor vital engine parameters such as AFR / Lambda / Turbo Boost etc.
a great many Serious Cars have been sucessfully
tested and mapped on our

always accurate, never any wheelslip:
current Le Mans 24 h Prototype approx. 650hp
Jaguar XJR V12 7,4l 747hp
Noble Street Version
Mosler 7l, 500hp, 700Nm (515 lbft)
565hp engine in Dallara Chassis
Questions & Answers:
Question 1.)† †So, how accurate is this dyno then ?
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
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
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 ?
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
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.
constant, 880 hp at the wheels mapping,
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
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>
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.
