Paul, Ellison is a substitute for a carburetor, some kind of 'new' technology that's been around for some time and seems to be simple & successful and has a good reputation.   Avgas only, like a Cessna.    While there's no venturi they still recomend carb heat.    I'm sure there's a size that's overkill for the motor now on your bench.   They offer units for hp greater than most of these rotaries can put out.

 

Your statement of 'carburetor or Cessna' really rang a bell with me, kind of a wake-up call.  As for expense, for me I wouldn't have to deal with the cost or issues you're encountering with the fuel-injection setup.  Microtech isn't that cheap and sofar not proven that reliable overall.

 

Rusty, why would you need more than one?    Consider Tracy's current intake setup for his Renesis, essentially remove the injector hardware and replace his throttle plate with an Ellison.    

 

I've been sketching manifolds this morning and i can see they'd not be that difficult to make out of either aluminum or steel.  

 

Warning, I have no first-hand experience with Ellison's.  Just what I've gleaned from magazines and the internet.
