Hi Joe, 

It does capture the essence of what I was suggesting.   There were other design features I had in mind too.   

(One of which would allow the concept to work with fuel-injection.)

Primarily, besides minimizing runners, I was thinking to minimize the twists-n- sharp-turns of the airflow from the outside air into the intake ports.     So the plenum shape is either:

) Wedged shaped (as viewed from above) with the throttle-body on the forward end, just like they have on ebay (http://i10.ebayimg.com/02/i/03/9e/4e/12_12_sb.JPG).  The airflow approaches the intake ports at not so much a 90-degree angle.   

- or -

) Triangle shaped (as viewed from above) with the throttle-body mounted at the apex opposite the intake ports.  Being so close to the cowl's side wall makes it possible to just grab the air from a scoop or NACA thing on the cowl side and run it into the throttle-body.  Fitting an air filter in there appropriately. 

-or- 

) modified triangle to try to deal with DIE, skipping details

Do you mean like this (see attached).  Fence post extrusion with carb on top.

Imagine taking their plenum, cutting off the runners, and then bolting this plenum onto the side of your motor over the intake ports without using runners.   Where the ported ends of the runners appear on the inside of the plenum you have ported entries into your intake ports.  Oh, and then use an Ellison as a throttle-body.     Is this wrong?
