Considering a '73
NET hp is also taken at the flwheel on an engine dyno. But the engine is equiped as it would be in the car. Stock air cleaner assembly, stock exhaust manifold running through stock mufflers, all emission controls, alternator, etc. Like I said, as it would be configured in the car.
So Gross is the ultimate hp possable while Net is in the car real world hp.
By the way, factory never rated cars at Rear Wheel HP, that is mostly a speed shop thing.
