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

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?

Hi Graeme,
I opened it also and installed there a taxi light (HID Xenon – check an attachment).
Now if you some day decide to go for 914 you have much less to do!
No reason for panic!

Well, in that case to make you aware of it:
Diverting air, rushing by with a speed of 100+ knots, from a smooth path
alongside the airplane, instead into a hole with lots of obstacles,
sharp turns, etc and letting it out again as a turbulent mass in the
wrong direction and with the wrong speed, is certainly costly in terms
of performance and efficiency. And in this case for no usefull purpose.
Maybe you have invested a lot of effort to make the airplane as smooth
as possible, in that case such a needless source of drag is an even
larger waste.
As a general rule you should close off all unnessecary holes in an
airplane. This is the reason why you have made the covers for the torque
tube access holes. You can leave them off without any ill effects,
except of course a reduction in speed and fuel efficiency.
