ELectric Fans on a Cummins ?
For $600 or so FLex a lite makes a fan kit for the CUmmins 5.9 Anybody using it? is there a noticable MPG gain running empty? Does it work well enough to cool the truck when loaded?

You have to be careful adding electric fans in combination with clutch fans because you'll unknowingly cause turbulent restrictions in air flow over the radiator. If one is not capable of flowing the same CFM as the other then one will always be forced to suck through or blow through the other when they're both running. And if they're both rated at the same CFM then there's no point in having them back to back. Side by side is different.
