Gotta boogie till you bust. Should go real fast with a clean RC plane and a high pitch prop. That was the reference I was thinking of. I wouldn't go with the sub piston induction. A pipe maybe, and higher exh timing. Maybe 180 degrees after shimming the liner and probably grinding or milling the exh port to get that. The closing time on the crank should be 60 degrees. Is it missing the boost port? Without going downstairs, I think there are just two bypasses.
