MOTORCYCLE DYNOJET

Extensive product development enabled Dynojet Research Inc.to pioneer the first single-roller , inertia-based chassis dynamometer for motorcycles in 1989. This revolutionary design measures horsepower and torque through the use of a rotating drum with a known mass. Energy drawn from the drive wheels of a vehicle is stored in the drum, and by measuring the acceleration of the drum and the vehicle's engine rpm, horsepower and torque can be calculated. This type of "inertia" dyno testing is highly accurate and repeatable, since the mass of the drum remains constant.

The benefits of this design were immediately evident. Therefore, with the development of a computer interface and software package, Dynojet began marketing the Model 100 Motorcycle Dynamometer. The Model 100 proved to be affordable, reliable, accurate, and above all, consistent , not only from one measurement to the next, but also from one Dynojet Dynamometer to another. This enabled the communication and sharing of test data.

The Dynojet Chassis Dynamometer has become the industry standard in chassis dynamometers worldwide because of its revolutionary ability to measure horsepower/torque with repeatability of 1% from Dynojet to Dynojet anywhere in the world!

How?
Isaac Newton said, (Force=Mass x Acceleration)
Force (horsepower) = Mass (weight of drums) x Acceleration (provided by the vehicle being tested)

Since the only variable in the equation is the vehicle, we can measure the amount of horsepower a vehicle produces at the rear wheels with an extremely high level of accuracy and repeatability. There are up to 4000 sample points in a typical Dynojet horsepower test! Dynojets use the (SAE J1349 rev. June 1990) correction factor, this is the lastest correction factor in use today. Allowing our customers to compare results with each other from all Dynojets worldwide. Test can also be measured using DIN, EEC, and STD correction factors.
