Has anyone tried running electric fans to improve mpg? And as far as things needing improvement on these engines in the SD's so far I keep seeing headers, y-pipe and exahaust. the air intake on these trucks seems to work as well as any of the aftermarket replacements. What about camper shells has anyone tried that? There not cheap but neither is bad gas milage.

Thanks Johnny for the feedback. You said you fabricated one for your navigator; did you use one fan or two? Also, did you build a shroud for the fan(s) or did you just bolt them on the back/front of the radiator?
If you’re willing to show off your work with some pictures that would be of great help to me.
What kind of increase in power and/or mileage did you notice?
when the fans kick on do you notice any draw on the electrical system? Your dash lights don't dim or anything do they?
Flex-a-lite sells a two fan bolt on kit for the f-250 that claims to move 4000cfm, but it does not use a shroud. I’m thinking that kit would be a good starting point but before I bet 600$ that it will work I would like to get as much information as possible.
If any of you guys know where I can find the answers to any of these questions I would really appreciate it.
Thanks,
How many CFM does the stock fan move?
Any suggestions about using OEM fans off of other vehicles or fans that may be used for other purposes than automotive?
Any suggestions on ways to build the shroud itself?
Plastic?
Fiberglass?
Sheet metal?
