The DynaPack Hub Dyno - Article
Autospeed have relaunched an article about the Dynapack- worth a read.

In Australia, the Dyno Dynamics roller dyno is king. It is used more widely than any other single type, and over the last decade its measurement has become the standard against which 'wheel horsepower' is measured. However, just because it's ubiquitous, it doesn't mean that it is the only way. One of its more recent competitors is the New Zealand-sourced Dynapack hub dyno, a vehicle dynamometer that bolts the dyno heads directly to the wheel hubs, rather than using a roller against which the car's drive tyres bear.
So what's a Dynapack like? What are its advantages (and disadvantages - all products have both!) over a more conventional roller dyno? Recently ChipTorque on the Gold Coast negotiated the loan of a Dynapack four-wheel dyno for a few weeks; Dynapack was pleased to demonstrate the equipment to a potential purchaser, while Lachlan Riddel of ChipTorque is a technology junky, always keen to experience something new. ChipTorque's current dyno is a two-wheel-drive Dyno Dynamics roller.
