On rg I would think the duct is pressurized from air between the gear  
doors. So I left mine open. With the big fan in the back I think I get  
cooling. I made my NACA's 1 inch wider than recommended 10 years ago  
and have no cooling issues IO 540. Oil 185. Never seen over 205 even  
summer over gross climbs direct to 12 k at 25/25.
