Today at 11:31=C2=A0AM
Kelly,

Sorry to hear that you won't be at Sun N Fun. I do= understand that you=C2=A0
would like mor= e info, but I will have to provide what I can now and the=C2=A0
rest later as I have already started packing the tra= iler for Sun N Fun.

The 200Z gearbox uses 2 sets of interchangeable gears allowin= g me to=C2=A0
customize the gear ratio fr= om 1:1 all the way up to 3.54:1, so getting a=C2=A0
gear ratio that will allow the 13B the rpms needed to generate g= ood=C2=A0
power and keep the propeller be= low 2700 rpm is the easy part. All of the=C2=A0
same features will be retained in the 200Z for lubrication and easil= y=C2=A0
supporting hydraulic constant spe= ed propellers. The propeller shaft=C2=A0
= rotates with the standard propeller rotation so more expensive pusher=C2=A0=
propellers are not required.

Pictures will be = taken as Sun N Fun where Ed Kelepeis will provide his=C2=A0
Mazda Renesis engine to display everything on. Ed has al= so finished his=C2=A0
new fuel injection = manifold to display as well. This is when I will get=C2=A0
all of my pictures to share with everyone. I should be ab= le to send=C2=A0
those out during Sun N F= un.

Du= e to the differences between rotary and piston engines our standard=C2=A0clutch mechanism will be changed to a damp= ening drive plate. This takes=C2=A0
advan= tage of the rotating mass of the gearbox and propeller to reduce=C2=A0
the weight of the flywheel while preventing d= amaging harmonics. This=C2=A0
also saves = a lot of weight several different ways and makes the whole=C2=A0
package more compact.

The initial display will use an exi= sting bell housing of cast aluminum=C2=A0
that is on loan to me. The worst thing about this bell housing is the=C2= =A0
starter is in the worst location poss= ible for using it with the 200Z=C2=A0
gea= rbox (MURPHY!). I have been able to extract all the critical=C2=A0

CNC bell ho= using incorporating several other features that will reduce=C2=A0
part count, interface complexities, costs, and put= s the starter where it=C2=A0
needs to go.=

I hav= e also located the sources for converting carbureted 13Bs to fuel=C2=A0
injection, a good ECU that controls the fuel= and ignition, and a=C2=A0
normalizing tu= rbo charger system that automatically prevents accidental=C2=A0
over boosting. The sea level boost is a mild 2psi an= d should maintain=C2=A0
sea level power t= o 16,000 ft.

That's about all the info I can provide right now. I'm sorry= if this=C2=A0
seems more like a teaser t= han all the info you were looking for, but=C2=A0
being in the early development stages has its limits. If everything= goes=C2=A0
well I might have a 13B proto= type firewall forward package on display at=C2=A0
AirVenture. Certainly there will be a lot more information coming = out=C2=A0
between now and then.

Thanks for aski= ng for more info. I will put out more announcements as=C2=A0
things develop.
