I'm going to attempt to describe this idea and see if anyone has tried it:
create two separate plenums, one for each pair of engine cyl by creating a baffle running along the inboard cyl fins. cover the rear and side with alum or composite leaving just the inlet open. Seal the inlet with normal baffle material. The inner baffle can be extended all the way to the inner cowl inlet section and cut to match the contour of the upper cowl inlet ramp thereby eliminating the need for the section of baffling which spans the forward portion of the engine just aft of the spinner.
The hard part is fabricating the inner baffle section to account for both cyl, and the 4 valve rod housings.
Surely someone has done this? If so, do you have templates for a lyc O-360?![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
