Where are the drawings?

No drawings = I'm=20 afraid. What I did with the Kolb installation was to use a small = oil/water=20 heat exchanger. To get greater oil capacity, I ran oil in the = larger=20 chamber that was intended for water. The oil from the flat plate = (that one=20 had a little leaky sumplet) ran down to the top of the cooler on one = side of the=20 internal core. The oil flowed through the fins on the internal = (water)=20 core, then the bottom of the other side of the cooler was connected = to a=20 fitting in the plate below the oil pump=20 pickup.

I never = had any=20 real airflow on the ground to find out how well the water cooled = the oil,=20 but I do know how well the water heated the oil. The two = temps were=20 always very close together.

I ran the oil level 1/4" above the baffle. Never a problem. We only = used 85=20 PSI and 9,000 RPM back then. Running a racing oil has the advantage of=20 additional anti foaming additives.
