The propeller isn't a problem. MT Propeller.
MT Propeller normally custom designs the propeller for the engine, airframe
and expected performance of the aircraft.
I understand MT Propeller already has a CS propeller turning 2000 RPM on an
aircraft with over twice the horsepower your discussing. (And probably
operating at a higher airspeed.)
If you're concerned about the price for a custom designed Constant Speed
propeller, I can give you an estimate. Or if you would prefer, I can fill out a
questionnaire to determine the design and the price.
I can be contacted at _jim@lessdrag.com_ (mailto:jim@lessdrag.com) . (There
is no cost for the questionnaire.)

I check out their website too. $35,900 for their 230 HP turbo model.
Prop rpm is 2200 max. This is good for efficiency/noise - however,
you might run out of pitch with typical propellers at RV speeds.
There are prop designs for low rpm/ high speed. I believe it allows
for reasonable tip speeds at high alt/high speed turboprop cruise but
these would be lots of money.... Diamond TwinStar might have a
suitable prop? Also DA-40TDI? (Europe only)
