Paul,

I don't know how much my static RPM's will help,
becase I have an adjustable pitch prop.  I adjusted it
to get about 5000 static.  Actual, at 5 lbs of boost
on the turbo in a climb, I'm getting about 5300.
It's a 72" prop, and I believe that the pitch is about
75".  I have the high pitch blades, and the pitch
range is 45-105" on the pitch.  Mine is about in the
center of the range. 

I'm using a 3 blade Ivo prop, quick adjust.  I bought
it because, I didn't know what pitch to run with the
turbo, it was cheap, and I can make it in flight
adjustable if I want to.
