Generally you lose about 15% through a manual driveline (~20% automatic), so that puts you at 124rwhp, ideally.
No idea how they rated these cars, but sometimes that rating was produced on an engine dyno with no accessories or water pump, so actual RWHP could easily be in the 100-120 range.

The germans have typically rated their cars with all accesories in place. The "old" US way was to have non of the accesories inplace. Hence, your 400hp "gross" V-8 from the late '60s would "net"significantly lower hp ratings.
German cars, porsche's in particular, tended to use the minimum hp that a sample of engines would produce. Others would use the "maximum" that one of their samples might have created.
So safely figure 147hp when NEW... then subtract 15% to get a realistic RWHP number.
