Top 10 Dsm Dyno Numbers

[Shane@DBPerformance]

There isn't any standard that I know of for chassis dyno calibration. So every dyno manufacturer has a bit different numbers that come out of their dynos. And some dynos can be calibrated differently too.

You will see general conversion numbers online from one dyno company to another, but from personally experience with Dynojet, Dyno Dynamics and Mustang Dyno, the usual quoted numbers are a bit off.

Uncorrected from highest reading to lowest dynos:

Dynapack
Dynojet
Superflow
Mustang
Dyno Dynamics

The Mustang dynos are hard to compare though. They can and often are calibrated differently from one to another. The one at Sound Performance in Chicago is calibrated to read like a Dynojet, while the one at RS Motors seems to read a little lower than most Mustang dynos I see online.

I don't know if any of the dyno numbers are the "real" numbers. Buschur had posted a short article on why the Dynojet numbers were higher. It had to do with how after careful calculations and building thier first dyno, the HP numbers seemed too low compared to the factory HP rating at the engine, so they ending up adding in a fudge factor to make the numbers seem more reasonable.
