Well my personal experience tells me your knowledge is lacking and incorrect. I dyno'd my old 35th on both a Dynojet (industry standard) and a Dynapack, within in a week of each other, on almost an identical morning (weather wise). Both results were within 1hp & 1ft/lbs of each other.

MY personal experience and logic would say that a HUB dyno (Dynapack) would get great numbers than a DYNOJET. Great Example is Church Automotive in Los angeles that yields greater numbers than dynojets mainly because it is reading the power from the hub. When you have to spin your wheels for a DYNO to read your HP it will be lower because power is lost when it has to be transferred to the wheels.
Of course the owner of the DYNO could make adjustments to his DYNOPACK to account for the higher HP. Not sure I don't own one just stating what I know from Experience and what logic tells me (power is lost at wheels)
