Rather than messing with the oil cooler size, location, and geometry, why not enhance throughput of cooling air?

Any heat exchanger needs good flow to the cooler, and equally important is good flow FROM it back into the slipstream.

The stock setup ignores proper and efficient routing of the air FROM the cooler, and the flow TO it ain't that hot, either.

Actually, with the stock duct in place, flow to the factory cooler is pretty damn good. In addition to poor extraction of the hot air, the thickness of the factory cooler contributes to it's poor performance. It's twice as thick as any of the reputable coolers (Mocal, Setrab, etc). As a result, the air going through the second half of the cooler has warmed substantially, reducing its cooling ability.

What about a pull-through fan controlled by a thermostat/relay?
