Klaus's O-200 makes much more than 100 HP. Probably more like 150.

He manufactures, uses, and sells high-compression pistons for the
O-200. Plus, when he's racing it's probably turning 4k rpm or better.

Book rpm for the 100 HP O-200 is 2750 at takeoff, much less at cruise.

Mike Arman didn't have to "trick" the Rotax 582 for power to get over
200 mph in the AR-5. He did trick the airframe, however. Read all
the books and articles in his bibliography and you can build his
airplane too. He doesn't sell plans but you could still figure it all
out and come close, especially if you're as sharp and as talented as
Arman. Of course, I'm addressing the original poster here, only.
