Fuel cooler

Watching an episode of Engine Masters today, and the discussion was, obviously, fuel coolers and the effects of cooler fuel on engine power. The best way they found was to utilize a transmission cooler that had as part of the cooler an electric fan. I thought this was intriguing. Has anyone tried this? It would necessitate running more fuel line and most likely have to be mounted in front of the radiator, but it would also add to the cooling of the radiator.

It did make a difference in power. They tried a cool can and CO2 sprayed on the carb. The tranny cooler seemed to work the best.

What does anyone think?
