IIRC the old system was rated WITHOUT any accessories and at the crank. The new system is with accessories and at the crank.

Is this power calculations based on the old hp system? In the 70's the system was revised somehow though I don't know all the details, anyway it was revised and the engines that were rated on the newer system were rated lower.
Anyone else know anything about this?
