Vehicle tuning imposes high demands on the retarder and can easily cause it to over heat, and operate out-with its most efficient temperature range. To alleviate this problem Dastek Dynamometers feature a unique fan shroud arrangement that splits the air. Cold air is drawn in over the hot discs, and hot air is pulled out via the 'chimney' arrangement.

"It is clear that Dastek's Dynamometer has been designed with an in-depth understanding of what is important to a tuner - speed, accuracy, and efficiency. For example with other dynamometers, you have to wait for the tyre to heat up or apply messy belt dressing, or high friction coatings. With Dastek Dynamometer, you just roll on, fix two straps down and you are good to go."
