Snowmobile Engine Dynamometers - Load Chart

The following graphs will help you determine if the absorber's load capacity vs. RPM curve is a suitable match for the engine to be tested.

"For better control, the engine being tested should not be at the extreme high or low range of the absorber's capacity."

Important: These maximum curves assume a full absorber. If you are running an inadequate water supply system, then you will not be able to reach these maximums.

WARNING: These are only the hydraulic torque (in foot-pounds) and Hp limits for each absorber. They do not take into account any other mechanical limits imposed by the dynamometer's hardware.

Minimum Hp requirements for these absorbers is too low to bother charting. For example, the combined bearing, seal, and windage drag at 4,000 RPM is only about 1 horsepower (climbing to just 4 Hp at 8,000 RPM). Note: The DYNOmite's integral torque arm fully captures this parasitic drag, so these do not represent un-measured power losses!
