Hub Dynamometer
A hub dynamometer, in contrast, eliminates the tires entirely. The vehicle’s wheels are removed, and the dyno is directly bolted to the wheel hubs. This approach provides a more direct and accurate measurement of torque and horsepower, as it removes the variables associated with tire deformation and slippage. A Dynapack dyno is a common example of a hub dynamometer. However, hub dynos require specific adapters for different vehicle bolt patterns, potentially limiting compatibility.
-
Single vs. Dual Retarder
Within chassis dynos, the number of retarders (braking units) also matters. A single-retarder AWD dyno applies braking force to only one axle and relies on the vehicle’s drivetrain to transfer that force to the other axle. A dual-retarder system, with independent braking units for each axle, allows for more precise control and simulation of varying load conditions, especially beneficial for diagnosing drivetrain imbalances or tuning specific axle power distribution.
-
Inertia vs. Eddy Current
Dynos can also be categorized by their loading mechanism. Inertia dynos measure power based on the time it takes to accelerate a known mass. Eddy current dynos, on the other hand, use electromagnetic resistance to apply a load to the vehicle. Eddy current dynos provide greater control over the testing process, allowing for steady-state testing and simulating real-world driving scenarios more effectively. An inertia dyno might be adequate for basic power measurement, but an eddy current dyno is preferred for comprehensive tuning and diagnostics.
