Jesse,
this is because I believe in the 8kRPM limit for unmodified engine parts,
and my goal is a practical engine without applying exotic technologies(could not
afford it anyway). The reason for the low prop RPM is the airplane I am flying
now, and which I am planing to use as a test bed. It is an AVID Heavy Hauler
with a 100hp Soob on a 2.62:1 Rotax C driving a 75" 3blade Powerfin. This is a
setup I am measuring against. By the way performance is excellent.
The G40 weight is 26lb. Abusing it? I don't know. All I know is that I have
been abusing the ROTAX for years without a problem.

Richard: Why cut off rotary rpms at 7500 ? 8300 at 3.3:1 would make a
nice 2500 prop rpm package and 9000 would give you more range than any old
lycoming. And, the idea of two 38 mm mikunis sure sounds like
a nice way to eliminate a lot of problems. How much does the hirth g40
weigh ? Wonder how much more than 140 it would take ?
