12v Electric Fans?

I will fab up a small mount to hold the bottles on when I do the electric fan kit.

The price on that Derale is right on! It is a little bit smaller than the factory radiator since the Derale is 31.62"x15.75" and the factory radiator is 36"x20".

That shouldn't be too much of a concern though I would think?
 
I picked up a fan off a taurus at the salvage yard for next to nothing. On high speed, it really moves some air. Might try to swap it in later this summer...

what yr taurus?

Can't remember, I picked it up for my mustang a number of year ago (it's a popular swap for those) and never used it. I'm sure a google search for mustang fan swap and taurus would find out what years to look for...

ok would this fan kit from this link that chevycummins put up be able to retain the fan shroud? Fan Kit

Those fans seem like they are kind of misleading. 7000cfm is unheard of with automotive electric fans.
I'd trust the Derale, flexalite, permacool, or even Summit racings brand before those.
 
The flex-a-lite fans I have dealt with had their own stainless steel fan shroud that mounted the overflow & windshield washer bottles on each end. Im sure that helps add to the price tag$$$

I've found a set of 2 15" fans on ebay with a thermostat controller for $100. we will see how well that works.
 
I'll just throw this out there.. I've run electric fans on 12 valves and CR's. On the CR, I did a before and after test at the drag strip. There was absolutely no difference in MPH at all. I actually regretted doing it, since performance was the same. On hot summer days in traffic, the stock fan kept it cooler. The electric fans worked, but not as well. I'd just like people to know this before they spend their money hoping for some type of gain. I also checked fuel mileage, and there was no difference. I was running two large fans.. I also made passes with the fans off and on.. Still no difference..
 
Which works better to push or pull?

on edit: I have gotten rid of my stock fan to gain access to the adjutable pump gear cover easier. Fan always would get in the way and I would always bust my knuckles on the fan blades.

Hey tank21, how hard were they to mount to the radiator?

They are so easy to mount, at least with the derale all you do is put these plastic thing through the fins.

About a half hour and it on the radiator. Now the wiring takes alil while.

Thanks Matt
 
I sled pull with my truck and i just need something to get this thing cooled off between runs with out having to let the motor run. I thought of just making a quick mount bracket so that i could hang them up in front of the intercooler while im waiting to run again. Put some alligator clips on the wires to easily connect to the battery's. I would like to mount them perment in addition to the stock fan, but that's gonna be a lot of work!

Also in the link that Chevycummins posted that Co. has an "Extreme" Fan Kit that flows 7000CFM!! for $350

The flexalite claims 5500CFM for $550ish

By the time i get to the end of the track the coolent is pretty damm hot,I am still running a factory fan and an electric water pump.
I want to see how much will change when i go with electric fans then if that doesnt change my temps much at the end of the track then im going back to the factory water pump....I am running a coolent bypass

Anyone else got any ideas on fans :poke:

7000cfm is a ton of air!
 
I cant seem to find any fans that flow more than 2700cfm from the big manufacturers. That why I am saying its alittle misleading.

i have them on my truck and if i had a way to actually test them i would for you all to see if they actually flow that much but i dont even use them as my truck never runs hot going down the road setting at an idle for an extended period of time i would turn them on and it would actually cool more than just driving down the road not by a whole lot but would run a little cooler and that could say a lot running the 4 core rad i have from my stock 6.5.


if you all have a way i could test the cfm of this fan i would do it. from what i understand they are are 3200-3500 cfm a piece that makes a total of the 7000 cfm they claim.
