"Flywheel" based one for comparison:
Ah no it's not.
250HP sounds about right on flywheel with above rear-wheel HP figure
Front whp, not rear wheel.
The video above is for a VN PP.
275hp is; OEM crank rated horsepower w/overboost, exhaust valve opened and in N-Mode.
This is a
chassis dynamometer which measures
wheel horsepower not crank hp. You can also calculate it manually at; 15%-20% loss from the crank thru the drivetrain to the wheels. This is a good whp rating for the VN. It's a little better than 10% loss, based upon this correction factors.
The above video is; 250 wheel rated horsepower (
not flywheel), on a;
Dynapack chassis dynamometer, made in New Zealand.
