Kelly Troyer stuart@autopsrus.com To Today at 11:31 AM 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.
