The Heart-Break Dyno!
What is the difference between Mustang dynamometers and the Dynojet DYNOs and why does Dynojet have better horsepower and torque results, always?
I’ve found an interesting article describing the difference and I think you would enjoy understanding the reason Dynojet cars are always faster and more powerful.
Dynojet horsepower / DJHP (chassis dynamometer)Dynojet horsepower is a marketing hp scale that was created to read higher than True / Effective horsepower. They were successful in getting the magazines to accept the inflated numbers and are now the de facto standard for retail magazines. In the 100 djhp area, djhp is about 15% higher than True and in the 200 djhp, it’s 18% to 20% higher. Most chassis dyno results that are published by magazines are djhp, causing confusion, as there is True hp, djhp and ”estimated djhp”. Commonly, the wide range of power sometimes reported is due to the error of djhp vs ”estimated djhp” vs. the actual, unmodified True hp. DJHP is not ”RWP” or ”wheel power”, it has its own factored up hp scale. Dynojet hp is always an inertia loaded sweep test.[hs_form id="0"]
