Mine is not flying yet, but my dams are not that tall. Maybe I should go back and change them. My 3300 is being installed on a Kitfox 5, which is a relatively slow draggy high wing aircraft. Thanks, Jim Crowder Kitfox 5 > -----Original Message----- > From: owner-jabiruengine-list-server@matronics.com [mailto:owner- > jabiruengine-list-server@matronics.com] On Behalf Of > BobbyPaulk@COMCAST.NET > Sent: Sunday, January 04, 2009 11:24 AM > To: zenith-list@matronics.com; jabiruengine-list@matronics.com > Subject: JabiruEngine-List: Engine Cooling > > > List, > many thanks to "Jeff" for the photos and directions for the dams in the > Ram Air Cooling Ducts.( Jabiru 3300 ) i installed the dams on the 2 > rear cylinders with only 1/8" clearance above the fins including the > steel fins on the cylinder.i also continued thru the gap in the spark > plugs to the outside edge of the duct. the temperature dropped from > 335 ~ 340 to 265.
