When comparing hub dynos, don't just look at the advertised horsepower ratings.
The maximum braking power is often calculated at a certain hub RPM. But not every car will spin the dyno at that speed. At lower hub RPM, the available braking power is also lower.
And there's another thing to consider: brake temperature. Maximum braking capacity is typically specified with cold brakes, but if the brakes get warm enough, their braking capacity will decrease.
This is why we publish two different power figures for our Dynolyze hub dynos:
🟠 Calculated braking power at 2 000 hub RPM – the calculated maximum at that speed.
🟠 Recommended maximum vehicle power – a more realistic rating based on normal workshop use, typical vehicle gear ratios and the fact that the brakes won't always be cold.
Of course, higher power levels can be measured under the right conditions, but we prefer to give also a rating that reflects everyday use, not just ideal conditions.
❗ Check the actual braking torque (Nm) of the brakes used in the dyno and compare those figures between different models, not just the advertised horsepower ratings!
