Other Chassis dyno's are able to handel high power outputs, why is your's only 750 Bhp per axle?

Our workshop tests 1000's of vehicles per year, and we would expect to see less than 1 in 500 with over 500 Bhp. Many claim to be able to handle greater power on roller chassis dyno's. However, without without excessive straining methods, traction is impossible. Wit impossible tie down methods, the validity of the results as the tyre deformation is very unpredictable. with such high power outputs, we would recommend using an engine dyno, as the cost of one is small when compared to the total cost of developing an engine to such a high specification. As the Dastek Dynamometer comes complete with almost every conceivable accessory, and is much keener priced than our competitors, you will be able to afford to buy your own engine dyno.

I'm looking to purchase a dyno and have been informed that a hub dyno is more sensitive than a conventional roller dyno.

We strongly disagree! We have tested most chassis and engine dyno's available and have yet to find a system that surpassed Dastek Dynamometer in term of sensitivity and repeatability.

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.
