From what I have read,
about 6 to 6500 is 
the sweet spot. 
Any input is appreciated. 
Thanks
Tom

Tom,

That implies 115-135 HP per rotor. What rpm are you planning on running it?

Tom and Group,
     Forgot to add that Stuart says this PSRU will handle up to 300 HP..........So should work
for a non turbo 20B..............

Tom,

  To my knowledge Stuart is not on this forum.........His PSRU's have been principally been used on 
Chevrolet V8 and Subaru engines.......The version to be adapted to the Rotary is basically the same 
as that used on the Subaru (With ratios appropriate for the Rotary) and a different harmonic damper...
  Time will tell if his PSRU works for the rotary...........<:)

Due to the differences between rotary and piston engines our standard 
clutch mechanism will be changed to a dampening drive plate. This takes 
advantage of the rotating mass of the gearbox and propeller to reduce 
the weight of the flywheel while preventing damaging harmonics. This 
also saves a lot of weight several different ways and makes the whole 
package more compact.



doesn't give me that warm & fuzzy feeling about the engineering.

Rotary Group,
    This from Stuart Davis of "Auto PSRUs"............Perhaps of interest to those still looking for a 
Mazda Rotary re-drive...........
