I recently went to the junk yard to find a taurus 2 speed fan, as I suspected they were all gone off of the 3.8 taurus. I found a 24v SHO taurus though (i believe it was a 1st gen) the fan is a 2 wire, so It's "single speed." I read somewhere that the "single speed" sho fans are actually controlled with a resistor and are actually variable speed, and when they have 12+ volts to them they run at a higher output.

I know a lot of guys who run the 2 speeds only really run them on low, so what I am wondering is if this single speed will be able to handle cooling my car. some info on the vehicle:
-s4 na
-afco dual pass
-220amp 1wire alt

the shroud is a little short for the rad, but I will be modifying it to fit properly.
I have searched and read just about every thread I could find that had anything to do with e fans, didn't quite find what I was looking for though.

any info is greatly appreciated!

considering you have a respun alternator it probably won't even keep up with the high amp draw of the single speed fan at idle, and that is when the fan will be running most.

Not respun haha it is a custom alternator that has been modified to fit my vehicle.

how many amps does it put out at idle?

Its an n/a....you cold rig up a long straw from the cabin and cool it sufficiently,

na I would have just kept it all stock, its pretty fool proof stock

iTrader: (9)

140 or more I believe, I can get you an exact number if you'd like.

stock wasn't cutting it on 100+ degree days in Vegas haha

Does anyone have any experience with this fan? I have chosen the parts I have for good reason.

thanks guys,

What kind of "experience" would you consider relevant?
Jackchild has done a lot of testing of various efans...

If you chose them for a good reason what help do you need?
What was your plan to control it?

the clutch in the fan was bad. if you changed it, it would have worked brilliantly.

also, do you have an under tray??

Alright guys I know I sound like a total noob asking a question about some fan I got out of the junk yard haha let me try to clarify some things. I have done everything to ensure the stock system I have is functioning as well as it can.

The stock fan and shroud will NOT fit due to the fact that the afco radiator is REALLY big. I do have an undertray, and everything related to cooling is in working order, My temp gauge has gotten much higher than I would like on hot days here under normal driving conditions.
I am going to be building an engine in this next year that is going to require higher cooling capacity so I figured why not upgrade now? (the fan will likely be swapped out down the road, this car is my daily driver as of right now, so it being in good working order is a must, until I get another DD)


I am asking simply if anyone knew of the output of, or had tried this particular fan out, as I could not find the exact one I was looking for.
I will likely use something similar to clokkers method with relays.

I will look up some of jackchild's posts
Edit: Searched the forum and googled this name and got nothing lol is there another name this person goes by?


Thanks again,

Sometimes a thicker radiator is worse, it does not allow proper airflow
From what i remember the single speed fan is pretty powerful, so,if you can control it there is no worry. I run my fan single speed- high

Jackchild59, if you want to be formal.
Here is a recent fan related post of his.

SpunRx7Boi

Im running the single 2 spd on low off a 40amp relay, it shrouds most of my rad and cools an ls1 on 100 deg days. diff from what your asking but just make sure your running a 80amp relay if you plan to run variable speed max.

To answer your Q intelligently here are a few specs
single 2 speed fan
Low:2500cfm
High:4500cfm

Don't quote me on this but i belive the 16" variable fan runs as follows...
Single variable speed
Min:26-2800cfm
max:4300cfm
You should be able to look up your fans p/n on rockauto or google to confirm flow. I would say with your setup, you'll be well in the clear...

power it up and find out. Use judgement from that. Like how I tested mine.

Before I left the junkyard, i actually went over to their battery section and tried it there real quick lol

Those are made up numbers and are total bullshit, unless you can post either a manufactures spec sheet with static pressure referenced flow details OR provide wind tunnel results which have static pressure referenced flow.

Next you will post the amperage pulled.

And it's jackhild59 to you buddy!

You have everyone doing that now!

Well I'll be damned.
I blame Evelyn Woods for that mistake but apologize anyway.

That came out too harsh. Let me apologize for my harshness and explain.

Let me also say that I did not mean that SpunRx7Boi made those numbers up, just that they are widely posted around the internet as gospel.

They are not real numbers. They are made up. Sometimes they are accompanied by amperage draw figures. Those are made up as well.

SpunRx7Boi

Lol, that was harsh but im glad you reposted..Thought we were gonna have to e-thug it out lol. I have never seen actual manufactures specs for the Taurus fans, however the gospel cmf ratings come from bench testing against aftermarket cfm rated fans. All cfm ratings for e-fans are gospel, there is no standard method of testing. The numbers are for marketing and set a comparable reference within said manufacturer. The short of it being you can conclude the low spectrum of a variable Taurus fan is very comparable to the low setting of the famous 2spd, which for most setups is plenty "cfm"

There is a standardized testing methodology for use in AMCA certified wind-tunnels. When a fan company uses that equipment and method, they have the right to state that the airmovement is AMCA certified. They will brag about it.

Look, aftermarket fan ratings are mostly fudged by the manufacturers, in the same way that audio amplifier ratings were/are fudged. You choose to base your measurement on bogus methodology that shows your fan to be a monster. Then the internet fanbois buy them and brag.

So...

Is the rating 'free-air'? Free air can mean anything. It might even include 'air-entrainment' as part of the rating. What is that? Look up the Dyson Air Multiplier for an explanation. That is a worthless measurement when pulling through a radiator core.

No OEM manufacturer will state the CFM of the OEM fans. There is not a business purpose to release those specs. They tell you it is designed to specifications. And they use wind tunnels to test and verify performance.

I even corresponded with Dorman who makes OEM Spec Taurus fan replacements. They would only tell me that the Dorman replicas 'Exactly meet factory specifications'.

I looked on lots of websites and found those and similar ratings to your post for the Taurus and the Mark VIII. I finally found a website that claimed the rating came from a guy who timed the fan filling 30 gallon trash bags and did the math.

Those sites usually stated amp draw as well. So I tested the amperage myself in this post:






Really. So if the amperage ratings are bogus, can you possibly believe that the CFM ratings are any better?

Now, if you want to know how much air a fan moves, you can't. But you CAN generalize when you compare fans.

A larger fan moves more air than a smaller fan, if they are pulling the same amps.

Two fans of equal aize? The fan pulling more amperage moves more air.

A fan with wider blades (ie covering a larger area of the circle) will likely perform better against greater static pressure (think thicker radiator cores).

A fan with thinner blades will allow more ram air flow when it is off .

Jeez, you seem to know as much about fans as that jackchild guy.
