Ive been hearing about the electric fans, here lately, im interested, which brand and where to get them for my 99 5.4

 

HI!... I've had good luck with my two 16" DERALE fans. They are 4400CFM combined. Been running them for almost 8 years now with no problems. 8 years ago they gost me $98(U.S) each. Now I believe SUMMIT RACING sells them for $120(U.S) each. Here's my set-up :

 

You should see the 3985 cfm single 16" Zirgo I got from Summit for my 64, holy cow. I went with a Flex-a-lite setup for the F-150, no. 270 and love the thing. Nice setup, but costly, around 4 bills.

 

How much if any power increase did you notice? Thanks.

 

HI!... The average is 15-19 RWH.P.

 

dang that is impressive, how did you go a bout wiring them

 

99, I would go with the Flex-a-lite 270 as mentioned. I personally have the Troyer (Deralli) fans and made a custom shroud to mount them. The 270 are much easier to mount from what I've seen.

Oh, there is a considerable difference with the fans as opposed to the clutcher.

 

HI!... I have mine wired to manual switches through 40AMP relays. I have a coolant temp gauge, so when I see it run hot I turn on one or both sitches.

Most here have temp sensors to turn the fans on at pre set temps automatically. I prefer my set-up after going through many fan controllers.

 

I would say that a solid 15-19 hp is there, I did notice some increase. The A/C is really cold too. Mileage picked up some. I'd have someone who knows how to wire do it, and solder whenever possible.

 

Hi.

The highlighted text above is the best advice w.r.t install reliability. With the currents involved, and the environment it's in, any other connection method will likeely cause problems long-term.

Also, choose a quality controller - either SPAL or DC Control. Unless you wanna be a switch monkey like Neal .

Seriously, adding manual override switches IS a good idea, over & above the controller. Indicator lights are a plus as well.

Separate controllers are preferred ( with two separate fans ) for failsafe redundancy.

So - got an electric nut in the family or friend? Buy 'em a case & get it done.

thanks a bunch guys gonna try and do this here soon

 

 

i agree totally, i have the deul 16" dorale myself fans have worked great for over two years, controllers fry out every 4 months or so so i am like neal switches

 

I have had the same controller for over a year...

 

Does anybody know the required CFM to safely run a 1999 reg cab 4.6l F150? I have heard that just over 3000 CFM is more than enough. It seems that the really nice kit from Flex-a-lite (the 270) has doubled in price over the last 2 years and is now over $500. I was curious if I could run something similar to my 5.0 Mustang fan from Flex-a-lite.
