Fuel cooler

David vizard has a video on his YouTube channel called “buy a can of beans & really boost power that shows how much a cool can will boost power. It has graphs that show before and after power on the dyno. That will give you an idea of the benefit of a fuel cooler.

If you have a 300 hp engine, the benefit may be minimal with the exception of heat soak after a hit like RRR says. Then again if you have a 3500 hp street outlaws deal, the benefit could be substantial. I can see no downside to having one.
