HUB DYNO

is a type of vehicle dynamometer that connects directly to a vehicle's wheel hubs after the wheels have been removed. This setup provides a more precise and repeatable way to measure engine power and torque compared to traditional roller-type dynos. 
 

HOW IT WORKS

Direct Connection: The vehicle is raised, wheels are removed, and the dyno units are bolted directly to the hubs using
specific adapter plates.

​

Power Measurement: It typically uses an eddy current brake (electromagnets) to create resistance against the vehicle's driveline.

Data Stability: By eliminating tyres from the equation, it removes variables like tyre slip, distortion, and pressure changes that can
skew the results on roller dynos. 

KEY BENEFITS
 

Accuracy & Repeatability: Precise control over the start and stop points of a run makes it easier to see small gains from tuning adjustments.

High Horsepower Capacity: Some high-end units can handle over 6,000 horsepower, which is often beyond the physical

limits of roller systems.

Enhanced Safety: Since the car is physically bolted to the dyno, there is no risk of a tyre blowing out or the vehicle "launch off"

the rollers if a strap fails.

Portability: Many hub dyno systems are modular and do not require permanent floor pits, allowing them to be moved around a workshop
