Should work out well, Dave.
The combustion chamber is only concerned with the total
pressure - it doesn't care how it got there. Whether low compression
rotors and lots of boost or high compression rotors with more modest boost
levels. There are some advantages, like when not under boost you will
get a bit more power and efficiency with the higher compression rotors.
Also, using high compression pistons starts the power level at a higher point
and the intake charge is not heated as much with the lower boost levels.
As you are aware, ignition timing, fuel ratio, intercooler and limiting
boost (and perhaps a knock sensor) will all help prevent
detonation.

Subject: [FlyRotary] High compression
Rotors
As it turns out, I am going to be using my turbo only for mild boost and
normalization. Keeping that in mind, I am considering installing high
compression rotors in the engine that I am currently building up. I am
talking a max MAP of about 40" but most of the time running a MAP around
32". I do have an intercooler and see max intake temps of about 110 deg
F. Street porting.
