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. UNBELIEVABLE. that is a
75 deg. drop. i was starting out with the dams too small.
you can learn a lot from this list if you go with the ones that know.
thanks again.
bobby
N131BP

Bobby,
Which aircraft is your 3300 installed on. 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
