yeah 18, BUT, realize that puts us at a mere 238.

 

Outstanding writeup, thanks.

 

someone was looking for this ttt

 

Thanks menace

This is one of the better threads I have read. This one needs to be a sticky for the how to.

 

you need to wire it?

I went through 3 wiring kits until I found the one I liked

HAYDEN electric Fan wiring kit, Part number 3647


why?
1. It has an adjustable thermometer for the On and Off of the fans, adjustable from 160-280 ( I think)

2. It can support Dual Cooling fans.

3. It has the A/C interface, to kick on the fans when the A/C comes on

4. You can wire in a manual on/off switch to cool down between runs.

5. You can get it at any MURRAY AUTO PARTS. The price is $34.99 plus $2.10 tax total $37.09.


IT is not a perfect kit, with the above fan you need to change the fuses to circuit breakers. I started with:

The Kit came with a 12v 25amp fuse which I tossed out.
I put 2 40 amp 14v circuit breakers in there.
The first one is about 2" from the battery (to protect that power wire), I installed an inline fuse holder and put the circuit breaker right there then sealed it with electrical tape, looks almost factory.
The other Is in the power going to the fan itself, the kit already had the fuse holder, I simply tossed the fuse and put in the 40 amp 14v circuit breaker.

I noticed on my old kit I had a 30 amp circuit breaker and it kept tripping as soon as the fan kicked on, fan would run for about 2 seconds. I went and bought a 40 amp 12v and it would run a little longer. The 40 amp 14v circuit breaker did the trick!!!

The Fan kit has a 40/50 amp relay and so far it has been working fine.

To adjust the fan "on" temp. I follwed the instructions. I installed it, and then started the truck, you let it warm up until the coolant thermostat pops open and the water starts circulating, I have a 160 degree thermostat so I knew somewhere around there it would open. Once that opened I knew I had to turn the little dial with a phillips screwdriver to set the temp for the fans. SO i was reaching down to grab the screwdriver and the fan kicked on. I'd say it was probably within a minute of the thermostat opening. (had to make sure it was opened)

one of my old kit had a radiator sensor that fit between the radiator cooling fins, that you slide through and put a clip on the end of it. This one had a similar sensor, but a completely different mounting kit. The new one has a plastic round zip tie that you side through and it connects to a plastic plate on the other side, you slide the sensor through the plate and it is fastened. (it looks much better than the old one and holds much better.)

BTW:
Soaps writeup is top notch
The fan can be bnought with employee discount for about $100-120
The wiring kit is cheap.
You can save yourself over $300 if you do it yourself VS. buying a premade kit from tuner

 

I just built the same setup last weekend I got my wiring kit form Autozone.. they got it from Hayden.

I know quite a few people in the body shop biz so the fan was free. Mine came out of a CrownVic one of the mounting tabs were broke. I cut the shroud off with vinal siding sheers. I used stainless and built L brackets so that the fan could be centered it loooks almost identical to J *cough* DM. The clearence is kinda tight but 1 inch is enough to clear the belt.

My total cost with new 1/4-20 bolts and all was $39.?? I cant remember exactally but I have some silver out of $40.

It was a 19 inch 2 speed fan but I just wired it with the Hayden kit to the high speed side.

The only bad part abou the Hayden kit is that it supports dual fans but they come on at the same time. Both come on with the AC switch and with the thermostat. SO you can't run the low side on AC and the high side with thermostat. But I didn't want to anyhow the high side pulls enough air it might possibly cut down on my 1/4 mile times... I will try to get some pictures. If I can get somewhere to buy batteries..

 

Is a 16 inch fan good enough, or should I at least get a 19? I found a 16 from summit for like 80 bucks.

 

No ****. But 18hp is a big gain. Hmm, I think I found a weekend project for my wittle 4.6

 

This is the exact post I've been trying to find. Like Grimace--what is the optimum size fan to adequately cool the engine?

 

use the ford one on the first page.

It will last a long time plus it is easy to find (any dealership) and if you know an employee of ford, use their discount.

 

Menace, you rock. If you are ever in OKC, and need anything, let me know.

 

Thanks for the info!

 

TTT. Great writeup. Bookmark it if you have to.

 

Just because I have nothing else to do, BACK TO THE SUMMIT!

 

My question is how many cfm does this fan flow? I have made a few electric fan setups and the first one failed because the fans (dual fan setup) I was using flowed a total of 2500 cfm and that was not enough to cool the engine when the vehicle wasn't moving. Thus my newest setup consists of 2 fans that flow 3000cfm each! Do you have any metrics on this setup? What kind of temps does the engine run at when sitting for 20 minutes idleing and driving around town etc.
