The true hp and BSFC figures could only be obtained from instrumented dyno testing. That's never been done to my knowledge.
We know that the Eggenfellner sixes were well down from the stock hp ratings due to their restrictive intake and exhaust systems since they're typically inferior in speed to lower rated, Lycoming powered, similar type aircraft.
