I have an old print out from the HiRPM Home Page on "Rotary Intake
Porting Explained" . On Peripheral porting they say: Torque at low
engine RPM is virtualy non-existant and idle speed is 2000+  RPM.
Expected output of 300+hp.
Seems like with PSRU 2000 RPM engine speed, the prop speed will be close
to normal idle speed for Lycoming.
What do you think?

BTW HiRPM page is gone somehow. I can not find it again.

My contention exactly. What may not work for cars might work fine
for aircraft. 

BTW the pressure unbalance that Jim mentioned in the 
R-Beat catalog with peripheral ports can be simply fixed.

When you fill the side port with epoxy (Jim recommends Devcon)
leave about a 1/16 to 1/8 inch cavity. That will equalize the 
pressure from one side of the rotor to the other. Jim and I were 
talking about that last week when I was down there.
