I was told to get Engine HP divide by .8

4th: 440 HP
5th: 470 HP

Did three runs and the best of the 4th gear run we kept
Each time we got to 160 mph, 7500 rpm got the electric cutoff, it was starting to flatline anyway. The Fuel and Air looks good all the way through.
It was 61 degrees outside. Oil temp never got above 250F
I asked how the Dyno itself was calibrated and the Tech told me it was all done through the software. I asked how often the big wheel is greased up and he said every 6 months or by hours whichever comes first.
Running Super Unleaded, Stock pipes, no oil cooler, just skin and bones.
Hopes this helps anyone else.
