Do any of you guys use them? I was thinking about mounting one simply to save horsepower when racing. Is it worth the effort?
I only have three and one-half inches between the rad and my pulley. Can I get a big enough fan in that space? How big, diameter and CFM, is necessary for a small block with moderate power?Joe

Joe I use one,it helped to cool the off.I use the black magic brand.There is about a 1/2 clearence from the fan and the water pump.Get the biggest CFM fan you can.------------------

i used tauras fan,it is a bad boy.the CFM is phenominal 3000+ but you need a big alt.it pulls 40 amps continuos.i had to move my radiator forward on 65 because even aftr trimming shroud you still need 4.25 inch between waterpump and rad

I love my electric fan. They are especially good in slow traffic or when waiting in line or staging. I use a standard size 3 core copper rad on my 331 with the custom fit fan/shroud from HotrodAir: http://www.hotrodair.com/pg21a.cfm ------------------

That's the Derale #16926 It costs $119 from Summit, fits 65-66 mustangs perfectly, and is only 3-1/4" thick. It's built in shround measures 15-3/4" x 15-3/4". Hotrod air sells it with a relay and wiring, and sells it as their AC electric fan. I purchased one for my car, and it moves a LOT of air. I can't think of a fan that would fit a 65-66 mustang better. Good Luck! ------------------

What year Tarus did you get it from? I may need a bigger one and as luck would have it I have a 89 Tarus in the yard with a bad tranny  ------------------

Hey Ron,Do you have an electric fan and a mechanical fan connected to you water pump? If so, does it flow even more air? Erik ------------------

There is a writeup on fordmuscle.com on the Tarus fan swap and they claim it to be a little over 2000cfm which is still good, but not quite 3000+

No just an electric fan,it works great.You should not need both.With the little Rad's in 65-66 Mustangs I'd think a pusher fan on the outside will get in the way of air flow. ------------------

I hooked the new Derale fan up to my big battery charger (which has an amp gage) and it showed 19 continuous amps... which is right in line with the fan's rating. I also hooked up the old fan rated at 1600cfm. The new one blew WAY harder than the old one! Either the old one was over rated, or the Derale is under rated. It moves some serious air. It's got a really powerful motor that would work great at pulling air through thick radiators. Those Taurus fans, etc. might be good for vehicles with wider radiators, but this Derale is the most powerful fan for it's size I've found. The 65-66 mustang's radiator core is only around 16"x16", and the Derale #16926 fits it perfectly. It actually looks like some sort of OEM unit. It's a top quality piece. I used some fairly thick 1/2" wide self adhesive weather stripping to seal the shroud to the core. I then mounted a relay to activate the unit since it draws so many amps. Good Luck! ------------------

I have twin spal fans on my car along with the Ron Francis thermostat kit. Spal rates the 2 11" fans at 2780 CFM. All I can say is keep your hat on tight when these come on . Spal makes many OEM fans, maybe the Taurus has one? I will have to look at my SHO tonight to check it out.Spal has a single 16" fan rated at 2360 CFM.
Check them out at http://www.spal-usa.com/html/dampframe.htm ------------------
