John,
Funny you would ask. I had lunch with Chris Zavatson today. He mentioned that flow thru the inlets is not laminar due to prop turbulence. I was told it was supposed to be laminar by an engineer who should have known. Maybe it would be without prop interference.

Steve can you illuminate who determined the internal airfoil was "optimized for laminar flow". I have been fascinated with Bowers Induction and properly sized plenum openings.

Gene,My hangar-mate developed the production version of this aluminum inlet backin the 1990's and sold it to James. http://www.romeolima.com/RV8/Cowl.htmAs you can see, it is captured by the upper and lower cowls and connected tothe plenum with sections of tire tube. The inside is an airfoil optimizedfor laminar flow. Steve Colwell --For archives and unsub http://mail.lancaironline.net:81/lists/lml/List.html
