Repeatability:

Our Dyno runs are repeatable to better than 0.3%.  Other dyno manufacturers claim to be repeatable, but no other chassis manufacturer is even close to the level of repeatability we achieve.  One large reason for this because we have eliminated the largest variable of all - the tire to roller interface.  Rubber tires don't hold traction against a steel roller very well.  Add a year or so of use, and the rollers become polished by the tires and traction decreases further.  Some companies charge extra for special coatings on the rollers - which quickly wear off.  When you have this variable link in your data chain, you cannot have guaranteed repeatability - PERIOD.  Sure a roller dyno itself may be repeatable, but as soon as you put a car on it, all bets are off.  Many people think that this slippage only occurs in high power situations, but we've seen it happen with 250HP Hondas - ask some of the import tuners who have had guys sitting on the hood and fenders trying to get the tires to hook up. With the Dynapack, we use a direct mechanical coupling to make absolutely sure that there is no loss, no slippage, and no inconsistencies in this area.  We have virtually no inertia to mask small details and we use hydraulics for the ultimate in sensitivity and precision.  The Dynapack is absolutely the most consistent and repeatable chassis dyno in the world.

Sensitivity:

We can reliably measure minute differences not seen on other machines.

Some examples include:

.010" change in spark plug gap
Differences between various lubricants
The alternator load when the headlights are turned on (in real time as well)
A single step fuel jet change
Different spark plugs

An example of this sensitivity:     (shown on very OLD software)
