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?

A mechanical fan will draw about 25 to 30 HP in full lock up mode. Ever see the size of a 25 to 30 HP 100% duty cycle electric motor?
It was not my intent to debate the merits of the electric cooling fan but.....
It does not matter how much the OEM fan draws, the question is how much air does it move and how close can the amount of movement can you get with an electric fan.
I understand the clutch fan moves 10,000 CFM
According to Flexalite their fans move 5000 CFM with 30 amps -
30 amps only equals .5 HP
So if all those numbers (your and mine) are correct then it would certainly benefit to convert to electric fans.
But my interest and my personal situation is different from a lot of people. I only plan to tow about half what the truck is capable of and only a a few times a year. I want to try for the best MPG when running empty because this is my ddaily driver
No offense intended but you're contradicting yourself as the amount of air flow from the compared fans is ALL that matters. If you cant get the necessary CFM out of the electric fans then who cares how much HP your saving because you'll be overheating in summer heat and towing. But if you only plan on towing half the CGVWR then you may be just fine.
