DYNO CHART

If you offer any aftermarket upgrades, such as exhaust systems, induction kits, high lift cams or engine managment solutions, then a Dastek Dyno is the best products foravailable, allowing you to extract the maximum performance from a cars engine. From conducting before and after testing on aftermarket upgfrades, to live mapping with so many hand features integrated, the Dastek Dyno will allow you to maximise your time while providing the most accurate, reliable and repeatable data to its operator. Most technicians don't realise the true benefits a Dastek Rolling Road can offer untill they see it in action themselves. It isn't just designed to tune cars and record power, the dyno is an exceptional problem solving tool when used correctly.

No matter what vehicle you have, we guarantee maximum power from your engine. On a CRDI diesel vehicle, adding the Unichip produces a peak gain about 50% or even more. On a diesel injection pump, the peak gain about 30% or more. The gains result obtains from accurate map sets that correct the Air-Fuel ratio and timing to produce maximum power. On turbocharged vehicles, we additionally modify the boost maps to both raise peak boost to the highest safe level and to start boost earlier and program it to reach its maximum quicker. At partial throttle conditions, your vehicle will deliver the best possible fuel economy while producing minimum emissions. When you push the throttle to the floor, however, your engine will make the most power available. It can be used to detect many malfunctions that can prove elusive when testing on the road. By simulating actual road going load conditions, you can preforma a variety of tests.

These areas alone can save you untold time and energy, by reducing the amount of external road testing required to replicate your customers problems, resulting in you being able to accomplish more work for the same amount of time, amximisin gyour profits, not to mention not risking your license, that safety of the employee's or customers cars.

Unlike most dynamometers, Dastek's Dynamometer has it's rollers machined both inside and out, to enhance high speed dynamic balancing. Furthermore, its close-couple roller arrangement replicates the vehicle's normal road ground clearance, which helps in the simulation of the air flow, and prevents 'drop down' problems associated with lowered vehicles or race cars with low front air splitter spoilers. The ground clearance advantages of Dastek's Dynamometer enable an exceptionally effective and simple vehicle strapping technique, not only securing the vehicle laterally but also longitudinally, preventing it from 'climbing out of the rollers'.By being able to use the vehicles original transportation anchor points, it eliminates any risk of damage to alloy suspension arms.

FANS

Proper vehicle cooling fans absolutely essential to dynamometer use and vehicle tuning. Nothing will hinder the tuning process more than inadequate vehicle cooling, resulting in soaring under bonnet temperatures, and reduced intake air charge densities. Dastek's knowledge and experience in this area means we have also produced our own range of high pressure centrifugal cooling fans, enabling quick, reliable and safe engine tuning. These fans come in either 20hp version for the main vehicle radiator cooling, or a 4hp directional model for inter cooler or sub-radiator.

DATABASE

A built-in software database keeps a record of every individual vehicle each time it has been tuned on the dynamometer. This database also builds up a running average of the entire power curve for every vehicle type entered. This can be used as a quick reference to see if an individual car produces similar power graphs to other vehicles of the same type, based on real life results, and not manufacturers' figures.

I'm thinking of purchasing a dyno, what would suite me better, a hub mount or roller type?

The one benefit to hub mount systems is total traction, so if extremely high-powered vehicles are the norm, then it might suite you better. however, the power capability of the machine is rarely matched by the proper cooling and ventilation required to support such high power. The other disadvantage is their inability to a coast down test. The advantage of using a Dastek Dyno is its superior sensitivity, and repeatability, much quicker installation of the test vehicle (a 4WD is ready to test in under 2 minutes, as opposed to around 20 minutes with a the hub mount) and results that are comparable with other motor manufacturers' figures.

I understand that you use a coast down test to determine flywheel power. Why, when wheel power is what makes you go?

The problem with measuring wheel power only, is that many factors can affect the wheel power output - tyre design, temperature and pressure, wheel alignments, gear box oil, viscosity temperature and level, wheel speed, final drive ratios etc.

As an example; take two very similar cars with similar modifications, both are tested on a 'wheel horse power only' dyno, Car A has 12 Bhp more at the wheels than Car B. The owner of Car B and/or the dyno operator begin looking for problems with the turbo chargers, ECU calibrations, CAM timing etc. If the test had been carried out on the Dastek Dyno, the coast down test would have revealed the transmission loss would have appeared excessively high, thus taking the focus away from the engine fault and pointing us in the direction if the drive line problem.
