when you measure power at the flywheel you have only the internals of the engien that cause a sapping of the pwoer

when you measure the pwoer at the wheels, you have to take into consideration a lot of losses through the transmission as in the clutch, the internals of the box, the prop, the diff, the cv joints and even the wheels all need power to make them turn, they don't just transmit the power wihtout requiring some of it to turn themselves so it's mroe of a guestimate at what the engine is actually producing
