This is a good "do it yourself post", for sure. If someone could take the time and is willing to do this Mod, with a few photos, it would probably be the best (and most appreciated) mod to date.I think 6 big ones is steep myself for what seems to be a relatively simple mod!

 

I have done this before, that is where the directions came from (actually, I just made them up ). The only complicated parts are finding the power sources. If you do not want it to be on a switch, the battery will work fine. If you were lazy, you could get away with not hooking it up to the air conditioning, but, your A/C would suck when you are idling.

 

There are so many different ways to go about building your own fan that it shouldn't be a problem for anyone to not have to spend $300 - $500 on a drop-in set up. I used a 12V source in the power distribution box to energize a relay wired directly to the battery. The power source is energized with the ignition so the fan runs anytime the key is on. I also installed a switch so I could run the fan at the track while the truck was off. It has worked great so far with no problems. If anyone wants to do it this way drop me an e-mail and I can give the specifics.

 

subscribing.... move along, nothing to see here.:o

 

Go with the JDM kit. It now comes with the a/c, manual toggle right in the harness. Get the water pump while your at it. They were running a special on the combo, call them for details well worth it. Brainless to install rather than conjuring up some make shift kit. The JDM kit is proven to perform and work, why try and get around it. You'll spend more time looking for pieces and engineering it. When you buy stuff from tuners you pay for their time and money for the R&D they put into the product. The 3 or 3 hundered bucks i paid extra rather than doing it myself is well worth my time and piece of mind. Just my opinion.

 

I wish JDM would offer that package again, i would like to get one. didnt have the money when they did. oh well

 

SpankDog,

Unless your heart is set on JDM, email Mark@LFP. He'll hook you up.

 

JL's e-fan kit includes the water pump.

 

JDM's post advertising the E-Fan/ Cobra pump lsits 15-18 HP. for the Fan and 4-5 HP. for the water pump.
I've heard real world Dyno reports of 9-10 HP. for both.
Have any of you Dyno'd before vs After??

you also have faster throttle response and quicker rev without the clutch fan. Plus your truck will run cooler and a tad better milage. Not to mention the manual operation of the fan.

 

And there is a lot less noise when the A/C isn't on. It seems that the stock fan on my last 3 Ford trucks makes far more noise than the engine and/or exhaust. I leave for work very early and try not to wake up the neighborhood. Now I just turn off the A/C when starting up and don't turn it on until I'm on Main St. Much better!

And yes, throttle response and SOTP are much improved. I thought I was going to get better gas mileage, but my last two tanks have been inconclusive.

 

I have a puller fan from a new 5 series BMW that I picked up for a different project. It is like 16 or 18 inches and has to speeds. You guys think its possible to setup a puller type fan on there. Looks like I would have planty of room.
