I have read in a few places where and electric fan will add around 15 horses and can give you up to 2 MPG better gas mileage.

Now that sounds like a lot of claims to me. What do you think about the electic fan replacement and what kind of performance increase would I see.

Also I occasionally offroad in the desert (sometimes over a 100 degrees) but rarely tow anything. Is an electric fan a bad idea when your engine is working hard at slower speeds such as 4x4ing?

Check my signature below and yes I got one of your chips...

 

Hi dcovell,

Nice to see you again, it's been a while!

We think electric fans are a good enough idea that we released our own Performance Products F-150 electric fan kit a few months ago.

The power gains that can be made on the F-150 & Expedition run from a low of 12 hp to as much as 15 hp, with the usual result being about 14 hp.

Now how much mpg gain you'll see varies, but there is indeed pretty consistent improvement there as well. In one of our F-150's here at Performance, installing our electric fan kit gave us right at 1.0 mpg, and our driving conditions aren't the best. We're in the mountains, so it's constantly up & down hills, though we have few stoplights.

There are a few people who have indeed picked up as much as 2.0 mpg from our fan kit, but I would say to look for something more like 1.0-1.5 mpg, anything more would be a real bonus.

What we have to remember here is that this is all just a byproduct of removing that static hunk of dead weight (10 lbs.) of the mechanical clutch fan, and that is a big help in certain ways, the engine no longer has to accelerate that mass.

Even at very light throttle you will notice that the engine has more zip and is more willing to gain rpms. Even just "blipping" the throttle sitting still, you can feel it grabs rpms significantly quicker, the engine is more willing to rev. It's kinda like underdrive pulleys only better, in that instead of reducing parasitic loss, you have completely eliminated one area of parasitic loss. The power gain fropm underdrive pulleys or converting to electric fans is virtually identical, but the eletric fan conversion gives better throttle response results, and is more noticeable in normal driving, I'd have to say, though we do like both mods of course, power is power.

I'd have to say that overall, the basic facts of what you've been hearing are pretty close to being accurate in our experience.

Our Performance Products fan kit uses a pair of 16" electric fans featuring fully enclosed fan blades & very heav duty components, from the fan motors to the dual independant adjustable fan controllers & relays. It also gives you full redundant capabilities should one of the fans fail (something we've never had happen, but it's better to be prepared!).

Give us a call to go over this in detail, we can go over all the exact specs of our kit compared to others, pricing, etc.

 

Thanks for the info. And as soon as I get some cash set aside I will most likley get an electic fan. I belive that this mod would be the next best "bang for the buck" as far as extra power/gas mileage goes.

My concern on gas mileage is not nessarily the money (run 91 octane for the chip) but if it takes less gas to get to the desert I have more gas to mess around with!!! Plus I am helping the polution thing a (very little) bit

Now does your kit have everything such as the thermostat, A/C relay, and other various items like the Flex-A-Lite fan?

Also how much, if you don't want to post the price please feel free to email me. me@dcovell.net

Thanks

Also after 7000+ post are you tired of typing or have carple tunnel etc...?

 

ooh ooh ooh, me too, me too. I haven't been able to find a kit for my superduty on the performance products site. I want it. Please give me the info I need to order it. Thanks a million, Mike.

This is not Mike, but I have one of his Derale 16" fan kits. It includes everything you need to install the fans. Mike has twenty plus pages of instructions - detailing exactly what needs to be done (including the break for a cold brew!). His controller has a lead for the AC so fan runs when AC is on. The fans have a variable control to set the turn-on temp. Each fan has its own controller and can be and should be set to different temps.

Mike isn't giving me any kick-back to say this, but that is one well designed fan kit. I am not easily impresssed, but this is a good deal. As far as price F-150online rules prohibit discussion of price.

You have to call Mike to order the Derale fan kit.

 

Hi thewhiteford, Peddler, dcovell, ..................

I hesitate to go over much more about our Performance Products Electric Fan Kit as it's a bit off topic for this section, and we need to stay within the rules of F-150 Online (especially as a vendor). So I think the best thing we can say is to please give us a quick call & we can go over all of the specific details on each of the features, what is involved in the actual installation, the configuration, the results, pricing, etc.

And of course to place orders for the kit while our web site is under construction, please just give us a call & we'll get it right out to you.

Briefly..................

In putting together the manufacturers of the various components, we dealt with virtually every name manufacturer in the industry & their engineering specs in most cases, it was quite a long involved process to decide on the manufacturer of each component. We dealt with Flex-a-Lite, Derale, Hayden, Permacool, SPAL, a couple of automakers, and more. The end result gave us the fully enclosed reverse-S fan blade design we wanted for maximum cooling & safety, and heavier-duty components compared to other fan kits (rugged motors, controllers & relays), with a configuration that is very similar in features & operation to factory dual electric fans in vehicles like the Corvette & Lincoln Mark 8.

Yes, it ties into the A/C of course, for improved engine coolant & cabin cooling compared to stock at lower vehicles speeds & when stationary. It's configured so that you can use it with any temperature thermostat, no need to change if you don't want to. Configured in a Low Temp & High Temp fan staggered configuration, the system also features full redundant capabilities.

To "thewhiteford," just in case you may not already be aware, you will not find our products at the performanceproducts.com web site, that is a completely different company. Our web site is currently under construction, just the home page is up now at www.TroyerPerformance.com while the catalog is being built, etc. For the time being, we do have the Superchips product line available for online ordering, the other parts need to be ordered by phone for now while our e-commerce structure is being programmed. Just FYI...................

To "Peddler1000," thank you for your kind post, that was very generous of you to say.

For all the other details, etc., please just give us a shout & we'll be happy to answer any questions about our kit.

 

I have one on my 4.6. I live in Poway if you wish to see the setup.

 

George, where do you work, I work in Mission Valley I rarely get into the Poway area but maybe your close to where I work.

 

I have the PPI fan kit on my truck. (see sig) I was in the dunes twice with it. The first trip I was monitoring the Cylinder head temp. The highest temp observed was 108?C. This was achieved going up a dune at 6500rpm. As soon as I crested and started back down it was at 92? by the bottom of the hill. Last weekend I was back and the highest temp was 112?. I installed 2 KC Highliters in the grill. I removed them a few minutes ago. I have a winch in front that obstructs the flow of air through the lower part of the rad. The added restriction of the lights was too much. It is a very well assembled kit and the instructions make it easy enough for a moron to follow. Because you mentioned off orad I would use all the mounting hardware supplied. There is a blue wire off of each controller that allows the connection of a second fan ( not used or recommended) that I used to power a light that lets me know when the fan is running. This allows me to also monitor the turn on temp of the fan. One last thing, if you run water install a kill switch to turn off the fans before entering the water. But don't forget to turn them on after you come out.

Thanks for the info, I don't run though water but I would guess the fans are not powerfull enough to turn when under water. That would require a lot of touque.

Now the temps that you gave me, I really don't know if those are good or bad. What would be a normall temp with a stock fan setup. Also what about a second fan on the transmission cooler, I noticed you don't suggest a second fan but why?

 

I have the duel kit. 2 x 16in. fans. I don't need the tranny cooler as my truck has a manual transmission.

Regards

JMC

 

Sorry to bug ya but what about the tempature, I am not very up with engines so please fill me in on what a normal operating temp is and what is considered bad.

 

I'm retired. I go down to Mission Valley atleast once a week. Send me an e-mail and we can make arrangements to meet. I'll bring along some info and you can atleast see what everyone is talking about and you can decide which way to go.
George

 

Mike you have to update your home page, your forgetting about us older guys again. Remember the old 4.9L, 5.0L, and 5.8L. Dont forget about us Mike, we paved the way for you new guys. BTW the chip is still great!!!! And do you have a fan kit that will work for the 5.0? And if I get it, would I need ot install a capacitor, since I have an amp that pulls 38A?
