CAR DYNO FACILITIES

At our premises in co.Kildare, we operate a state of the art 4wd Dynamometer test bench, also referred to as a ‘Dyno’ or ‘Rolling road’.

This equipment is used for the development of all our tuning software on cars, vans and 4x4s in a controlled and safe environment.
Here we can custom tune and test each vehicle individually, measure power output, datalog the engine data and perform a variety of different tests under controlled conditions..

The dyno we operate is one of the most advanced in the industry. Here are some of the main advantages of this dyno setup

Single large diameter roller setup

which is far greater than the more commonly seen twin roller setup which can struggle with grip and tyre deformation issues. Due to the tyres and weight of the car being positioned directly on top of the rollers with a larger surface area to grip to, even high horsepower cars can be tested without having slip issues and excessive tyre heat and deformation problems.

6000nm Twin retarder setup

capable of measuring up to 2000 wheel horsepower! We might never see this amount of power on our dyno, but due to the fact it is this powerful, it means its not working near full capacity when testing cars which are even up to 900 hp which we do occasionally see. Most dynos will struggle with excessive heat when testing these types of cars and can struggle to measure the power consistently and require long cooling down periods.

Mechanically linked synchronization

of the front and rear axles via a driveshaft, clutch and two gearboxes (most 4wd dynos are non-linked). This is very important for 4wd cars and especially on models such as BMW Xdrive, as it doesnt risk putting abnormal stress on the transfer box which can occur on a non linked dyno. Ensuring the front and rear wheel speed is the same as it would be on the road results are far more accurate to real life.

Even on 2wd cars we can match speeds at both axles and even test these vehicles without having to disable traction control or disconnect wheel speed sensors etc.

Dyno cell

COOLING AND EXTRACTION

The environment for testing the car is equally as important as the dyno itself. It is absolutely essential the engine is cooled sufficiently and able to breathe in clean cool air in order to perform safely and consistently. Our room (dyno cell) is constructed with insulated cold room panels.

We have 30kw of frontal cooling power which draws fresh cooler air from outside via a duct at the front of the cell. This fan forces the air at up to 160km/hr at the front of the car to cool the engine and intake temperatures.

The cell also has 7.5kw + 5.5kw extraction fans which quickly removes exhaust gasses and heat from the room, meaning we have fresh air entering and bad air exiting the room. All of this results in the car performing consistently on the dyno and similar to real world conditions.

Many tuning companies who run dynos don’t invest properly in their dyno cell, and therefore cannot produce the accuracy and repeatability required especially on higher powered vehicles which generate a lot of heat and exhaust gasses.
