Electric Fan cooling in "HOT" Texas ???

How many OEM cars are there in Texas that are running electric fans just fine?


A quality electric fan will push more cfm than the stock clutch fan so it's going to cool BETTER.


The day i ran my 12s at the track was low 90s and i hot lapped it 3 times and the temp never got over 180.

For folks that don't live in such a climate, there's a huge difference in cooling system performance between 90-95*F and 110-115*F. With many cooling systems, the dynamic temp just tends to phase shift. Some people think nothing of letting a car idle at 225*F.

At a minimum, I'd want a 3.8L Taurus fan, with upgrades being a Mark VIII or Viper fan. A 94-95 Mustang fan and 3.8L Taurus fans are the minimum fans I run in So AZ.

What i would do if i were you is look into buying a NEW Mark VIII fan, not a junkyard version, and get yourself a really good controller and get it all as reliable as possible. I don't think the cooling ability of that fan is in quesiton, i would think more along the lines of getting something that won't fail on me (as in burning out). While the junkyard fans are great for me, my fan doesn't run as often as yours probably will so i would be more comfortable with a brand new fan, and i personally would rather have a new Mark VIII fan than most of the aftermarket fans out there.

dude!

There are many electric fans avaliable from mustangsunlimited.com and most of them will get the job done.
I also suggest getting a hi po water pump as well, if you dont already have one.
Saves the hastle of your stang pissing antifreeze and water b/c the stock motorcraft pump couldnt keep up.

I RUN THE 94-95 TAURUS FAN FOR 3YRS NOW WITH A $20 ADJ. TEMP FROM ADV. AUTO AND 130 AMP ALT. NO PROB IN HUMID AL. EVEN AT 100 TEMP STAYS 180-190 IN TRAFFIC.

I have limited space thanks to the 3 core radiator and large pulley on my procharger. Last I looked only small electric fans that do not cool enough for a v8. Is that still true?

I went with a dual Y2K Dual Ramcharger fan with Custom brackets for my setup. *I* like having two fans. Because you know that eventually, one will die. Also, you get better radiator coverage with two smaller fans.

I STRONGLY suggest that you stay FAR FAR FAR away from ANY POS aftermarket fan!!! But, then again, it's YOUR ENGINE that will overheat, puke, and self destruct. So, do what you want. The POS aftermarket fans are just that - POS fans made to be LOW COST. An OEM fan is designed to go for ~200K miles. So, what makes sense to you?

Here's great info from a thread that has a lot of info. Note: You can buy the fans from him, get the fans on ebay, buy the fans new yourself, get the fans from a local junkyard, buy the fans from the stangnet classifieds, etc. What ever you do is up to you. I vouch for neither of the above for being the best. I will say that I did buy my fans from him.

Fan Info
Looking for an electric fan upgrade to install this summer to solve your overheating problems. Let me first say that I personally run one of these Mark VIII fans in my 1992 GT with a DCC and it works awesome and is in my opinion the best setup to go with. I have a buddy with a 700rwhp 03 Cobra that also runs one of ... Mark VIII fans and it works awesome for him too.

I have personally flow tested all 4 of these fan types to find out the actual CFM flow ..
o The Mark VIII and Taurus (Taurus and Mark VIII fans have same motor) fans flow about 4500 CFM and some have done about 4900CFM.
o The older style Dual Ramcharger style fans flow about 3500-4000CFM
o The newer Y2K Ramchargers flow about 3000-3500.
All 4 fans are dual speed fans also.

The Ramcharger style fans do not go all the way to the bottom of the radiator, so I suggest using some through-radiator ties to hold it flush against the radiator. ...setup the Ramcharger style fans with the brackets on either side of the fan so that the wiring can either be at the top or bottom, or on the older style Ramcharger changing bracket sides would make is that the taller fan motor can be either on the passenger side or drivers side. i.e. in the pictures below, the fan is setup so that the wiring is on the top and the taller fan motor is on the drivers side, but could be reversed

The Taurus fans ... I find that most people prefer to use the through-radiator ties with it, though I do not recommend using those to fully mount and hold a fan to the radiator.

Fan Dimensions
- Mark VIII dimensions are 18.5 x 22 x 6 and 18" blades, not including the tabs.

- Mark VIII w/ trimmed tabs and trimmed depth dimensions are 18.5 x 22 x 5.25 and 18" blades

- Taurus fan dimensions are 18.5 x 23 x 5 inches, and 17" blades

- Y2K Dual Ramcharger style fan dimensions are 26 1/2 in wide by 15 1/4 in tall and a slim 3 5/8 in deep

- The older Dual Ramcharger style fan dimensions are 15 x 25 x 3 inches deep in the center and 4.5" at the small fan motor center and 5.75" at the tall motor. 13" fan blades.

Oh yea, I'll add that you MUST upgrade your alternator and wiring! Also, I suggest a true PWM true variable speed fan controller like the DCC.

Also, I have to add NEVER EVER use through the radiator ties on a fan - NEVER!!

You WILL eventually wear a HOLE THROUGH YOUR RADIATOR RESULTING IN A LEAK - PERIOD! Make strong sturdy brackets that mount the fan to the radiator support. If you have to, then use angle iron for braces since they don't bend. Don't do a half *ss job just to end up with a POS setup that can possibly result in your engine overheating.

BTW: Guess what someone did when they where a teenager? People can either learn from my mistakes, from my experience and education (CS/EE/ME engineer since Mastodons roamed the earth ), or not.

The Mark VIII fan flows up to 4900 CFM?! WOW! My Flex-A-Lite fan was supposed to be a hot rod, and it only flows about 3300. Thats crazy.

Any idea on how fast the VIII fan spins? I know mine spins around 2450 RPM. I wonder if modifying mine with a VIII motor would be a good upgrade...

Where do you get dual Y2K Dual Ramcharger fan? I do not reconize that one
