Why is Dynapack better than a traditional dynamometer (roller)?
* Full control over the desired performance
With Dynapack, it is possible to set a maximum engine speed and / or pressure (boost) the maximum, so that the engine never works beyond its limits.
* Elimination of the friction between the tire and the roller
This removes from the equation the poor adhesion of the tire, the friction in the bearing, its temperature and its diameter.
* No retention harness
As the vehicle is directly screwed to the load cell, the movement of the car in the tests do not affect the results.
* No inertia
This controls the vehicle speed and measure the smallest fluctuations.
* Reliability
Because of all the above advantages, the results between trials were identical to 0.3%.
* Accuracy
The Dynapack is so accurate that it can play variations caused by:
Dynapack is a device designed with advanced technology which applies a variable hydraulic pressure while remaining accurate. This is accomplished via a tether attached directly to the vehicle wheels, to simulate highway driving.
Dynapack has a unique hydraulic mechanism that quickly and accurately measure the engine power, torque and other information related to vehicle performance. The apparatus operates with a sensitivity such that it is possible to detect whether the headlights are lit!
Dynapack attaches directly to the axles, hence this eliminates the disadvantages caused by the distortion due to the tires such as noise, the steering wheel torque, traction loss, warming tires and the variations due to the type of tires. Direct coupling to the axles Dynapack also allows to make very sensitive readings to a wide variety of motor speed.
The Dynapack uses adapters mounted directly to the axles. Once the adapter is attached to the vehicle, they are inserted into the hydraulic absorption unit. Hydraulic pumps create a calibrated load to the vehicle by calculating the rotational speed of the axles and the engine speed, compared with an acceleration curve. As all vehicles are different, this method provides a precise load on the dynamometer as we would feel it for everyday driving.

* Accuracy
The Dynapack is so accurate that it can play variations caused by:
- A change of .010 "of an inch away from the electrode candles
- A difference between different lubricants
- The load that brings the alternator to the engine when the headlights illuminate
- Different brands of spark-plug

- Accurate results of the measures taken - no inertia to distort the data.
- Reliability - identical measures between trials close to 0.3%.
- Portable
- Stress reduces engine - trials can last between 2 and 30 sec minimum for full power performance, torque, gas and data acquisition.
- Low Noise - no tires friction
