Paul,

   Getting some sort of standardized, low cost, easily understood,
   well-documented EFI system for aircraft Wankel engines would be
   welcomed by many.  But those people are primarily
   computer/electronic/microcomputer hobbyists or those looking for the
   last 10% in fuel efficiency or performance.


   For the rest of us, a
   cheap, simple carb-based setup would get the job done in a very
   straightforward manner.  Heck, if I were enthralled with the EFI
   experimentation I might _still _route the injectors parallel with a
   dead-simple Holley carb as a back-up.  One twist of a valve would
   open the fuel line to the Holley and a switch at the end of the valve
   throw would disconnect power to the injectors.

   A proven, inexpensive PSRU is the "most needed" item right now for
   the majority of us.

   My humble opinion.

   Neil Unger is building six PSRU's as we speak. Get your order in
or get left out. These are 3.12 to one with the proper rotation.

Here is a super simple side draft carb that uses an  off the shelf Holly
float bowl and a MacNealing leaning kit.

Contact Larry Childs.

I have a bunch of slide throttle kits to go along with it
for $50 dollars each.

Here is a slightly different configuration. It is a little weird but
it will fit under a low cowl. It is made from stock 180 and 90 degree
2 inch OD tubing bends tig welded together. Real low cost on ebay

The only difference is the aluminum plate that mounts the stock holly float bowl
is a bit longer. That gives a bit more room for the fuel plumbing on the
sides of the float bowl.

BTW Larry Childs did those incredible rotor housing 3D models.
