Hi,
Could you send some pictures of the installation? It would help
with the analysis.
As for now:
2. I would get rid of the oil thermostat. In my plane, there has never been
a problem with oil getting not warm enough (190 deg F+).
3. The added scoop may actually interfere with the NACA inlet. See my
webpage
http://www.utdallas.edu/~klaus/Airplane/cowl_inlets.html
for a scoop that I installed to REDUCE cooling for slow flight,
but still get good cooling during high-power flight.
4. NACA inlets work only well when the airflow is essentially
in line with the horizontal axis of the inlet. This means that during
climb in hot weather, the angle of attack cannot be high. For
my plane, this means no climbing below 70 kts unless
the air is quite cold, say 60 deg or below.
5. Finally, can the air get out of the cowl? Look at the bottom
lip on the same picture showing the modified NACA inlet,
on the above web page. One way to test for this is by a
water gauge that measures pressure differential across
the oil cooler.
Hope this helps. Please write if you have questions.
Best wishes, happy flying,
Klaus
