Al,
        Do you have any photos of your oil cooler install showing the airflow path?

My oil cooler is in the wing root.  The intake is on the bottom just behind the spar, and the exit is out the top further back.  It matches a coolant rad in the other wing.

The first pic show the oil cooler.  The second is the inlet “scoop”  - not really a scoop, just an airfoil lip that extends down into the air flow about 1/2”.  The third pic shows the rough ducting (early version of exit fairing) for the coolant rad; the oil cooler is similar, and the fourth pic shows the exit fairing. The flow through this cooler (and the wing root rad) is enhanced by the normal pressure difference between the bottom and top of the wing.  At this position of the wing the difference should be higher at higher angle of attack.
