To add, the DynoJet uses an SAE correction factor, which was 1.01 for my GR86 dyno, where as the Mustang uses a weather correction factor (WCF, between 1.75 and 1.2 for my cars, depending on the day).
I don't know what the % difference is between these dynos, but there is obviously going to be some variance just based on all the different variables, including the dyno.
To me, the important part is keeping the car on the same dyno throughout its mod lifecycle, to most accurately show the gains. The comparison of my old cars to my GR86 is neat to see, but not a very equal comparison because of what I mentioned above.
Below is the uncorrected and corrected (WCF) numbers for my modded BRZ (don't laugh  ) |
Was the new car burning 91 ?
