I know that with a standard Cessna or piper you usually see about 2100-2200, which times 2.17 would be about 4600-4800. The key to power with a rotary engine is rpm. As with any fixed pitch prop, you'll have to strike a compromise for the pitch setting, that gives you good climb, and cruise, and the turbo will add another variable. Until you get to do some high speed testing, you won't really know what your top rpm is, so everything's just a guess for now. I would personally like to see climb rpm in the 5500 range for a 2.17 gear drive.
