The main difference between the Mustang and the Dynojet is that a Mustang
is a loading dyno and the Dynojet is an inertia dyno.
With an inertia dyno, the only load being placed on the vehicle is the
weight of the rollers. With the Dynojet, that weight is only about 2600lbs.
So if you are tuning a car on the Dynojet, you are tuning the engine to push
around 2600lbs. That's fine on the dyno, but as soon as you get the car on
the street, the car probably weighs closer to 3500lbs. So the engine you
just tuned to push around 2600lbs is pushing around about a 1000lbs more
weight. This additional load on the engine is going to cause the engine to
detonate.
Whereas the Mustang is a loading dyno. We have an electromagnetic brake
called an Eddy Current that allows us to apply additional load on to the
vehicle. We also have a patented program called Road Load Simulation. With
this program, we can simulate the weight and aerodynamic drag of the
vehicle. So when you are tuning the engine on the dyno, you are tuning it
to the amount of load that it normally sees on the street and therefore it
won't detonate when on the street.
As for the Dynojet reading higher than the Mustang, that is correct. But
if you look at almost all of the other dyno manufacturers out there, they
read numbers closer to ours. About 6 months ago, there was a magazine
article in "Sportscar International." This article was an interview with
Mark Dobeck, the founder and original owner of Dynojet. In the articles he
goes on to explain when he made his first motorcycle dyno, they weren't
getting wheel horsepower numbers that he thought a certain motorcycle should
get. So he incorporated a fudge factor into the number. That fudge factor
has been present ever since in all of their dynos. That is why they tend to
have higher dyno numbers than other dyno manufacturers.
If you have any other questions, please let me know.

Comments: WOULD LIKE TO KNOW THE PRIMARY DIFFERANCE BETWEEN A MUSTANG
DYNO AND A DYNOJET. I HAVE BEEN TOLD BY VERY RESPECTABLE RACERS AND TUNERS
THAT YOU COULD POSSIBLY DETONATE ON A DYNO JET DUE TO NO LOAD PLACED. ALSO A
DYNO JET GIVES RWHP RESULTS 10% HIGHER THAN A MUSTANG DYNO.?
THANK YOU FOR YOUR EARLY REPLY
