    Any of you guys successfully switch out your fan hub for an electric fan? Considering doing this since i ran across a tow truck with a 400 big cam that had 4 electric fans instead of a belt driven hub. But not sure how if it would cool enough on long grades grossing 80k. This particular operator stayed pretty much local in eastern north Carolina so no worry about making the engine work hard on long pulls.

    Didn't you ask this a while back??
    But stupid idea IMHO.
    The factory fan is all you need .

    If my math is right, it will gain 50 hp after factoring in the extra draw on the alternator. If a guy changes turbo cam and injectors to get more power would you say that was stupid?

    I'm sure Orville and Wilbur probably had people tell them that flying was a stupid idea.

    Get your truck on the dyno with the stock fan running... install the electrics... dyno...

    It's only money, man. Blaze that trail.

    Be an interesting comparison. Just for the heck of it I would be curious to know what kind of CFM the mechanical fan pulls on my Freightshaker. No idea, Im going to guess roughly 15,000?

    I do know the factory ford 6.0L fan on a f350 pulls over 10,000 cfm at full song.

    I'm willing to bet the fans on our trucks pull at least double that..

    You'll never get the cooling capability out of electric fans as you can the stock 36" 9 -11 blade fan.

    If you actually use your truck like we do here in hot weather pulling 140,000lbs
    Electric fans would never work , ever.

    Yes it's a stupid idea .

    According to horton my 799067 pulls 14000cfm. If all i did was light loads or local stuff i would switch over in a heart beat. The only thing kept me from it is worry i will get halfway up fancy gap or flat top with 50k on and not be able to keep it under 220.

    One of the mines here has all the rads/coolers in their Cat dozers mounted on the roof. There's about 8 electric fans total (I think they've got a radiator, condensor, hydraulic cooler and transmission cooler up there).

    Edit: I forgot to mention each of these fans was about 18" so unless you were empty or on the flat all the time I don't think you'll get enough air moving through there.

    I don't pull 140k lbs. Absolutely no comparing the cooling requirement of engines pulling no more than 92k lbs and those pulling 140k. Completely different applications. That's like saying because your engine can't be air cooled no engine can.
