The Tunehouse Dyno Cell and Wind Tunnel
This is no slap up a few walls, setup an exhaust extraction fan… This project took a couple years to design and about 6 months to build and tune the room.
“One of Australia’s Most State Of the art Dyno Cells”
Jim being the perfectionist that he is has spent two years in the research and development into the building of such an international class facility prior to starting the project. Once the enormous suction fan (looks like a Boeing 737 engine) was installed, the tuning of the room and both inlet and outlet plenums began. Air flow and environmental characteristics where tested and a number of modifications where made to allow the simulation of a wide range of operating conditions. These ongoing modifications (some of them being major reconstruction works) took a lot of time and effort.
A lot of time and effort has also been put into the acoustic design of the room. The room suppresses the unwanted resonance and amplifies the important frequencies to assist the tuning process. A couple acoustics engineers where employed to provide input into the design of the room to allow this to happen. The room has been tested and the final results are highly satisfactory.
As a result the dyno room should really be called a mini wind tunnel functions without the assistance of a separate fan in front of the car. Wind speeds of up to about 160 km/h can be achieved. Different operating altitude pressures can be simulated.
The major advantages of this dyno room is that operating conditions, temperatures and air pressures can be simulated and reproduced to maintain a constant tuning environment. In the past the Dynopack dyno was too accurate but the environment could not be controlled and hence small improvements as a result of research and development could not be measured. With the ability to control the environment we have improved the quality of testing and tuning and can measure and repeat results as little as 1 rwkw.
Eg. The Dynopack is that accurate that it can measure the effects of load on an engine by turning headlights on and off. This might sound a bit ridiculous but for those who are after maximizing the return on their investment in modifications every kw here and there counts!!
The room is now “tuned” and ready for use. This is the only Dyno cell of it’s type in Australia.
What does this dyno room provide?
State of the art Dynopack Dyno able to hold up to 1200 rwkw at any RPM. 895 rwkw has been measured on a supercharged car. (Bolt’s onto your hubs with no slippage, losses to 0%)
Wind speeds of up to 160 km/h can be produced through the wind tunnel
Ability to control and stabilise environment variables
Full suite of diagnostic and monitoring equipment
Able to obtain Dyno run repeatability second to none
Environmentally friendly 1000 litre cooling tank to reuse water
We recommend that people pop in and have a look at our facility themselves. It is quite simply, very impressive!!! Jim and Tunehouse pride themselves on being known for “The Best Performance Tuners in Sydney”.
