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.

Kelly,

Sorry to hear that you won't be at Sun N Fun. I do understand that you 
would like more info, but I will have to provide what I can now and the 
rest later as I have already started packing the trailer for Sun N Fun.

The 200Z gearbox uses 2 sets of interchangeable gears allowing me to 
customize the gear ratio from 1:1 all the way up to 3.54:1, so getting a 
gear ratio that will allow the 13B the rpms needed to generate good 
power and keep the propeller below 2700 rpm is the easy part. All of the 
same features will be retained in the 200Z for lubrication and easily 
supporting hydraulic constant speed propellers. The propeller shaft 
rotates with the standard propeller rotation so more expensive pusher 
propellers are not required.

Pictures will be taken as Sun N Fun where Ed Kelepeis will provide his 
Mazda Renesis engine to display everything on. Ed has also finished his 
new fuel injection manifold to display as well. This is when I will get 
all of my pictures to share with everyone. I should be able to send 
those out during Sun N Fun.

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.

The initial display will use an existing bell housing of cast aluminum 
that is on loan to me. The worst thing about this bell housing is the 
starter is in the worst location possible for using it with the 200Z 
gearbox (MURPHY!). I have been able to extract all the critical 
engineering data from this bell housing to design a stronger and lighter 
CNC bell housing incorporating several other features that will reduce 
part count, interface complexities, costs, and puts the starter where it 
needs to go.

I have also located the sources for converting carbureted 13Bs to fuel 
injection, a good ECU that controls the fuel and ignition, and a 
normalizing turbo charger system that automatically prevents accidental 
over boosting. The sea level boost is a mild 2psi and should maintain 
sea level power to 16,000 ft.

That's about all the info I can provide right now. I'm sorry if this 
seems more like a teaser than all the info you were looking for, but 
being in the early development stages has its limits. If everything goes 
well I might have a 13B prototype firewall forward package on display at 
AirVenture. Certainly there will be a lot more information coming out 
between now and then.

Thanks for asking for more info. I will put out more announcements as 
things develop.

Thanks,
Stuart Davis
