I mounted a 9 inch SPAL fan on the stock intercooler. Fits pretty good. Tapped the power from the rear wiper motor which I had already removed. I turn it on at the track or when I get ambitious. No test data, but the fan works on an oil cooler.
IMHO, on track, I think an oil cooler without fan might actually be better since the fan will end up blocking the air. Similarly, the way factory did the intercooler - air has to go thru it (& the A/C condensor) to get into the engine bay, hence the great air flow (engine sucking air in). If air can go around it, then the cooling effect on the intercooler will diminish. But I'd still think a fan on top will block air flow at track speed.
