Q:

Why do I get more power on an inertial dynamometer than I do an absorption dynamometer (or vise-versa)?

  A:

There is no right answer to this question.  First and foremost - never compare numbers from two different types / makes of dynamometer - they almost always disagree.  This “problem” can typically be attributed to how the test was run and how the numbers are interpreted – not to poor workmanship.  Make sure your comparing “apples-to-apples”.

However, there is disparity in the dynamometer industry, much like any other industry, and one should perform their own due diligence as it concerns investigation prior to making a decision to buy.

For our part, Mustang Dynamometer does not put its stamp on products that do not possess the characteristics and accuracies as specified on company issued media. What’s more, our dynamometer design has been certified for its soundness, fitness and accuracy by authorities in the field of automotive testing – with the former having been further validated by millions of hours of testing; our numbers are accurate.
