Hey ya'll,
I am thinking more and more about buying E-fans for my 2001 S-crew.

I am wanting to know: A) how other people hooked them up
B) What the best fans are
And Finally C) What was the turn out from going with Efans? (Gas milage, power, ect.)

Im think i want Flex-a-lite 270 fans. But not sure on the controller. Is that one that comes with the 270 fans good?

Pic's of any set-up would be nice.

Thanks guy's,
Tanner

 

I believe they say the Fan/clutch assembly that is on the water pump weighs a good 10-15lbs. You get that off the crank and it should be good for 1-2MPG and 5-15RWHP. I dont have a EFAN setup yet so I cant tell you the test.

 

I'll be going with the Proforms...

$67 each and they flow 2100

I'm gettin gthe JEGS temp switch for one. it turns on at 200 and shuts the fan down at 185. The other fan will be wired in with the AC compressor and will turn on when the AC turns on, also a manual switch for wheeling and other situations where I need more cooling... these fans only pull 9.0 amps, which is a plus...

 

If yer looking for MPGs, forget E fans. The clutch when fully engaged is supposed to run at 80% speed of the pump. When you are going down the hiway, it runs at 20% speed of the pump and doesn't require any HP from the engine at all. Fuel mileage is not going to change. They are fabulous if you like A/C in extreme heat and in stop and go traffic. Problem with most are the controllers which fail often. They also have benefit if it is an engine that you will be racing. When staged and building heat into the tires, the clutch will engage and eat into HP at launch. Otherwise, they are a toy.

 

Most electric fan rigs I've read about here on F150online seem to be pretty good at setting trucks on fire, if that's what you're looking for.

Or rather, a lot of them seem to be more trouble than they're worth. Just my opinion.

 

I have had 5, count 'em, five, electrical melt downs. One almost burnt through the case of the battery...that would have made a mess!! I've had two holes in the radiators repaired due to using the rods to mount them. I'm currently running with two bad controllers that I don't trust. Other than that they've been great . I consider It a challenge at this point to get mine set up properly. Finally got my mounting down good, just need to tackle the wiring next. Have my controller picked out, just need to do it.

I will say they completely transformed how responsive the motor is and how free the motor revs. It is one of those mods you can feel in the seat of your pants. Would I do it again?? Hell no. Do I regret it? No.

 

what the hell are you people doing wrong?????


you obviously cant wire these with speaker wire...


I got all 10 gauge wire to hooke mine up with...

 

I purchased pro-comp fans and troyer controllers and have been running them for about 3 weeks. I made my own mounting bracket from alumnium bar stock from Lowes. The power difference is not much at all but I have been pleasantly surprised with the mpg. I went from 12.9 mpg to 13.8 mpg in those 3 weeks. I think the one thing to definately make sure of is the temp settings on the controllers. If they turn on too early your engine will not reach optimum temp.

 

I'm all for anything to free up a little low end, but from what I've read over the years, they seem like be to much of a hassle IMO.

Clutch fans are maintenance free and hardly ever go out. I replaced the clutch fan in my 98 last winter because it had 250,000 miles on it. When comparing to the new factory part, they felt almost identical on the bench,- vised .

I haven't heard of mpg increases, but I have heard from good sources it's worth about 15 hp.

 

hmm....... if they dont work out, they go on race car....


I dont see why people have so many problems... using the right gauge wire, right rated relays, good grounds, circuit protection, etc, shouldn't be a problem

 

Controller melt down has been a major issue in the past. Could even contribute to electrolysis problems. Then there's setting them and hoping they keep that setting. You can install manual switches, but that's something I never want to have to use.

Idunno, for some it's worth dinkin around with. Nothing wrong with that.

 

From all the support I've searched out on my electrical issues, it's been pretty unanimous that they've all been due to the controllers in some form or another. All of my wiring has been from what came with the controllers. Never had a need to splice or replace anyhing in. If the wiring that comes on the regulator is insufficient for the job, then that's a whole nother story now isn't it??

My next controller will be the new SPAL all digital unit. Pricey, but nice!

 

I was very happy with my efans and the extra power. I likem.
The problem is mostly the cheesey cheapo controllers used and the poor grounding done during installation.
I use this controller, no problems and precise settings.

i have yet to have a major problem with mine. they are initially a hassle, but once you get everything squared away, they are awesome. I noticed a 2 mpg improvement (city) and about 5-10 more RWHP

 

what this 'controller' talk??? set it to a friggin temp switch and a heavy duty relay.....
