Looking back thru my notes, I seen a posting that Buly's plane needed 126 inch of outlet air to make the cooling system work.  Is this amount necessary for tractor installations?  At present I have an opening 4 - 1/4" x 11 - 1/4", with the exhaust to exit short of the opening to help siphon out the cowling heat.  I really don't want to get everything buttoned up and find out it isn't going to cool.  What are you fellows using on your RV's.  Thankyou in advance.  JohnD   I need to get some foam for remolding the cowl, what can I get at the lumber yard that will sand and work well?
