Dynomet DK offers a range of roller type dynos:
For cars:
- inertia roller dyno for 2WD vehicles,
- inertia roller dyno for 2WD and AWD vehicles with an option of synchronising front and rear sets of rollers,
- inertia roller dyno for 2WD with an eddy current brake for steady state testing,
- inertia roller dyno for 2WD and AWD vehicles with an eddy current brake for steady state testing and an option of synchronising front and rear sets of rollers.
Dynomet DK also makes motorcycle roller dynos and dynos for 1:5 scale model cars.

Features common to all Dynomet roller dynos:
1. The rollers are very heavy, weighing close to 1000 kg per axle. That's almost twice as much as rollers found on other popular dynos. The heavier the rollers the longer it takes to accelerate them, allowing for more precise tests with sufficient load. Light rollers will have problems even with new 2.0 and 3.0 diesel engines due to their high torque values. With the DYNOMET heavy rollers, cars with up to 700 HP can be measured in inertial mode, which gives up to 1400 HP with the AWD dyno.
With the optional eddy current brake up to 1000 HP per axle can be measured.
2. The rollers are knurled to eliminate wheelslip and reduce noise.
3. Maximum roller speed - 400 km/h (250 mph).
4. Rollers are balanced to less than 1 gram.
5. The optional eddy current brake, has a maximum braking value of 1500 Nm (1100 ft/lb).
6. Dynos with the optional eddy current brake can work both in inertia mode and brake mode, where desired engine rpm or speed can be set.
7. Power and torque graphs and current power output for dynos with brakes.
8. Ability to compare up to 4 graphs, handy if comparing 'before' and 'after' graphs.
9. Display of speed, rpms and data from up to 8 auxiliary sensors (intake, oil, water temperature, air/fuel ratio, EGTs etc.) with ability to log them during tests.

DYNOMET software has in-built DIN 70020 correction.

For all AWD dynos the car's wheelbase can range from 218 cm to 330 cm.
AWD dyno dimensions: 532 x 250 x 65 (cm; length x width x depth), total weight - ca. 5000 kg.
2WD dyno dimensions: 86 x 250 x 45 (cm; length x width x depth), weight - ca. 1400 kg.

DYNOMET dynos are modular and can be upgraded at any time.
2WD dynos can be upgraded to AWD and inertia dynos can be equipped with a brake.

In the synchronised AWD version one axle can be easily decoupled for cars with single axle drive.

AWD DYNOMET dyno

Each set of rollers knurled and connected together with a belt to eliminate wheels slip.


Exemplary power test on a base DYNOMET inertia type roller dyno without eddy current brake.
The car makes around 500 HP and 650 Nm, but thanks to the heavy weight of the rollers the test
is possible and provides sufficient load for this turbocharged engine.
Test conducted in 6th gear, maximum speed around 320 km/h.
