D I wouldn't dismiss the 195hp claim out of hand. I've heard figures close to that from people I consider reliable. The guys here in the U.S. running D-Sports Racers where getting some serious numbers. They were doing things like running custom cranks, along with titanium rods et al. I remember seeing guys with those flat square screen oil filters taking them apart every day inspecting them for bits of bearings. They were rebuilding after every weekend. The cylinder heads had some really radical modifications, with the intakes reprofiled.
