Where are the drawings?
No drawings I'm
afraid. What I did with the Kolb installation was to use a small oil/water
heat exchanger. To get greater oil capacity, I ran oil in the larger
chamber that was intended for water. The oil from the flat plate (that one
had a little leaky sumplet) ran down to the top of the cooler on one side of the
internal core. The oil flowed through the fins on the internal (water)
core, then the bottom of the other side of the cooler was connected to a
fitting in the plate below the oil pump
pickup.
I never had any
real airflow on the ground to find out how well the water cooled the oil,
but I do know how well the water heated the oil. The two temps were
always very close together.
I ran the oil level 1/4" above the baffle. Never a problem. We only used 85
PSI and 9,000 RPM back then. Running a racing oil has the advantage of
additional anti foaming additives.
My thought would be to
do without the sumplet on this version of the flat plate, and I would
still use only one drain to the cooler. I'd have to choose the location
carefully, to make best all around use of the drain. I'd like to
leave maybe 1 qt of oil on top of the plate, to give me about 3.5 quarts
total.
BTW, did I mention
that I'd be using the oil flow to turn a hydraulic pre-rotator
:-)
Thanks,

myself into a Rotax 582)
