Thanks Rusty,
1 7/8 sure sounds small to me, as did the diameter of the first couple versions of ED's new muffler. But then you can't depend on what I think of these diameters. Yes, connecting the runners together into a common plenum and fed by one Ellison was what I was thinking since the mixture is being drawn into only one chamber at a time. And having to buy 2 Ellisons would probably be a 'no go' for me.
George, you're saying one at 1 7/8 bore is not adequate for one combustion chamber, that it would take two to support each combustion chamber?
Tom, my air-pump a Renesis.

Rusty,
Those sizes are what Jerry is running for his PP and should be fine i.e.
2 of them.

Hi Tom,
I can't say I understand it, but maybe Ken or someone will jump in and bail me out. I gave up on the idea of using an Ellison when I realized that the EFS-4-5 (180-225 HP) model only has a 1-7/8" bore. I've been worried that I was on the verge of choking my 13B with "only" 1-5/8" bores for each rotor. Now I suppose you could connect the runners for both rotors together at a common plenum, and feed it with a single1-7/8" bore since both rotors aren't requiring a huge airflow at the same time. That seems like it should work, and I'd love to see someone try it. Just hard to step back from true fuel injection.
Cheers,
Rusty
