Hi Graeme,
When I built my plane, I also cut out that inlet. It is still open after
10 years and 800 hours and I am not aware of any ill effects. I have
never had any cooling problems and in the winter, I have to partially
mask my oil and water coolers to maintain temperatures. I would suggest
leaving it alone.
Cheers, John

Subject: Europa-List: lower cowl opening for 914 only?
From: "graeme bird"<graeme@gdbmk.co.uk>
Had a sudden panic that I had unnecessarily opened up the lower cowl starboard
NACA duct and that it was only required for 914 inlet and not my 912. I cant see
what its for for the 912ULS as it would only cool the oil tank (which is already
too cool in flight) and possibly one end of the exhaust.
Is it necessary, has anyone filled it in?
