Manufacturer
Dyno Dynamics
Model
450 DS 4WD Rolling Road
Specification
2 wheel and 4 wheel drive chassis dyno test cell has the potential to run to 200mph with 1200 wheel horsepower handling (but not 3 wheel but who wants to map a Robin Reliant anyway?).
Cooling
Huge cooling fan capable of moving 33000 cubic feet of air per minute.
Measures:
Power and torque at wheels, power and torque at flywheel, air fuel ratio, air intake temperature, ambient temperature, barometric pressure, boost, road speed and more.
Why?
We invested in our 4WD rolling road so that we could create the best possible performance upgrades safely and legally and have the ability to live remap ECU's in house. The Dyno has the ability to hold load which allows us to precision tune an engine. The rolling road also serves as an excellent diagnostic and data logging tool.
This is a trusted dyno dynamics quality dyno. The Dyno Dynamics dyno 4WD rolling road is regarded as being one of the most accurate chassis dyno's in the world. They have now become the industry standard. An independant testing of rolling roads by Performance Tuner Magazine put the Dyno Dynamics Rolling Road as the most accurate.
1) Accurate, repeatable wheel horsepower figures
2) Eliminate tyre slip on the rollers with the unique roller and strap-down design – no more sitting in the boot of the car to keep it on the dyno!
3) Safe, controlled tuning environment
4) Capable of measuring up to 1200 wheel horsepower
5) 2 or 4wd, manual or auto capabilities
6) ShootOut mode allows for accurate results that are comparable worldwide as it eliminates any possibility of manipulating horsepower figures
ShootOut mode was developed by Dyno Dynamics primarily to eliminate "Operator Technique" and as a tool for measuring horsepower accurately and CONSISTENTLY for ALL Dyno Dynamics dynos. No other dyno allows for such worldwide standardised comparison. When you get your car dyno-ed in ShootOut mode, you can rest assured that the horsepower figure is an accurate representation of what your car is actually pushing out at that time (so no more wondering whether the results have been "fixed").
In addition, the unique knurled design of the rollers and the tie-down system utilised on Dyno Dynamics rolling roads ensure that there is hardly any tyre slip on the rollers. Tyre slip is not only dangerous to the engine and transmission, but the power readings become inconsistent. Excessive tie down on some rolling roads can also cause tyre deformation and inaccurate readings. With Dyno Dynamics, this problem is eliminated.
Prices
Rolling Road Power & Diagnostic Runs
Our rolling road is just perfect as an advanced diagnostics tool and data such as Power, Torque, Boost Pressure, Air Fuel Ratio etc. can all be logged and at the end you'll receive print out showing all these values. The charge for this is £50 inc VAT. Ring for block booking/group buy.
Remapping Sessions and discounts.
Remapping 4WD rolling road sessions can be booked in conjunction with the regular visits by a remapper. The charge for a rolling road remapping session is £88 inc VAT per hour (excluding the remapping, see the remapping page for charges). We provide a fully trained Dyno operator and access to the machine, including sensors and data software. If you book a rolling road remapping session and remapping with us on a pre announced mapping day then you receive a 10% discount on the 4WD rolling road session. If you have a already booked with your own mapper then why not meet him at our rolling road?
