Choosing the right hub dyno depends on what kind of vehicles you work with, how much braking capacity you need and how much space you have available.
Dynolyze offers three different hub dyno models: SMALL, SMALL PLUS and MEDIUM. All three use the same Dynolyze software and control system, but differ in braking capacity, physical size and hub reach.
Let’s take a closer look at which model might be the best choice for you.
SMALL – Compact and Lightweight
The Dynolyze SMALL is our most compact and lightweight model. It’s a great option for workshops with limited space or for users who need to move the dyno frequently.
Each SMALL hub is equipped with a 1 750 Nm eddy current brake, giving a total braking torque of 3 500 Nm per axle in a 2WD configuration.
The calculated maximum braking power at 2 000 hub RPM is 840 hp. For normal workshop use, we recommend the SMALL for cars with up to approximately 500–600 hp.
The SMALL is a good choice for:
- Street cars
- Naturally aspirated and small turbocharged cars
- Junior single-seaters (F3, F4, Formula Regional)
- Rally cars
- Workshops with limited space
The SMALL hubs are easy to move around and take up very little storage space when not in use.
One thing to consider is the hub reach. The SMALL has no extended shaft, so vehicles with narrow rear axle may require a model with a longer shaft.
SMALL PLUS – More Braking Capacity in a Compact Size
The SMALL PLUS offers significantly more braking capacity than the SMALL, while remaining physically smaller than the MEDIUM.
Each SMALL PLUS hub is equipped with a 3 300 Nm eddy current brake, giving a total of 6 600 Nm per axle in a 2WD configuration.
At 2 000 hub RPM, the calculated maximum braking power is 1 600 hp. Based on our real-world experience, we recommend the SMALL PLUS for cars with up to approximately 1 000–1 200 hp.
The SMALL PLUS is a good choice for:
- High-performance street cars
- Turbocharged cars
- Track and street drag cars
- Drift cars
- Cars with wide body kits
- Electric cars
Another important difference compared to the SMALL is the extension shaft.
The SMALL PLUS has a shorter extension shaft than the MEDIUM, but it provides extra hub reach for vehicles with wide tires, fender flares or wide body kits.
This makes the SMALL PLUS a good option for users who need more braking capacity and better hub reach but don’t need the full size and capacity of the MEDIUM.
MEDIUM – Maximum Braking Capacity and Extra Hub Reach
The Dynolyze MEDIUM offers the highest braking capacity in our range and is designed for demanding high-power and high-torque applications.
Each MEDIUM hub is equipped with a 4 600 Nm eddy current brake, providing a total braking torque of 9 200 Nm per axle in a 2WD configuration.
At 2 000 hub RPM, the calculated maximum braking power is 2 500 hp. For normal workshop use, we recommend the MEDIUM for cars with up to approximately 2 000 hp.
The MEDIUM is a good choice for:
- High-power race cars
- Drag cars
- Hillclimb cars
- Other demanding high-torque applications
- Electric cars
The MEDIUM also has the longest extension shaft of our three models.
This provides extra reach when connecting the dyno to vehicles with wide tires, wide body kits or narrow axles.
Despite its larger size, the MEDIUM hubs are still mounted on wheels and don’t require permanent installation. You can move them aside when you need the workshop space for something else.
Which Model Is Right for You?
If you mainly work with normal street cars, naturally aspirated or smaller turbocharged engines, the SMALL is often all you need.
If you work with more powerful modified cars or need extra hub reach, the SMALL PLUS offers a good balance between braking capacity and compact size.
And if you regularly work with very high-power or high-torque vehicles, the MEDIUM offers the largest braking capacity and longest hub reach.
Remember that the recommended horsepower ratings are approximate maximums, not minimum power requirements. All three models can also be used to measure lower-powered vehicles.
It’s also worth considering what kind of vehicles you might be working with in the future. Choosing a model with some extra braking capacity can be a good investment if you’re planning to expand your tuning business.
