I can't fit my black magic fan with the radiator. So I need a good eletric fan thats about no thinker then 3.5" 3.375 or thinner would be even better. No wider then 16"-16.5". I'm looking for a puller fan that will be used all as a full time fan.
The black magic claims to move 2800cfm of air. So something close to that would be great.
I've found a few Derale,flexalite,spal,fans. I was hoping to get some real world advice too.Ron ------------------

I know one thing, don't go with the Zirgo. They are WAYYYYY under the 3300 cfm rating that my box said. Its very quiet but that is because it isn't flowing any air.Darn near everyone i know run SPAL fans and are extremely happy with them. There are people running the Ford Taurus fans but i think they may be thicker than what you are looking at. I've heard they flow close to 4000 cfm  ------------------

Some fans are advertised with CFM ratings they could only dream about. The Derale fan has a very conservative rating. It blows like crazy. I've got one on my car. It has a half filled block, and a measly electric belt drive water pump. Cools fine.  Derale# 16926 None better. Fits a 65-66 mustang radiator PERFECTLY and blows like a hurricane. Best of all, it's less than 3-1/4" thick. 15.75" x 15.75" I have one, and it beats the pants off a generic 16" electric fan. It's a stud, drawing 20 continuous amps, so make sure you've got a good alternator. http://www.derale.com  http://www.derale.com/electricfans.shtml They make an excellent ADJUSTABLE thermostat that screws right into the water jacket with a 3/8" NPT sensor. It also includes a relay. I've got one, and it works great.  Adjustable temperature range from 150? to 240?F
3/8 MPT probe threads into water jacket

Same fan on the car for 5 years and still works as new.
Only draws 8 amps and still moves plenty of air.
Remember that I do not have a K-Mart aluminum radiator either. ------------------

I have the same Derale fan the Mike has. It works well, and blows like crazy. You will definetly need to make sure your Alternator can handle it, big power draw, especially on startup. Keep an extra relay handy, mine burnt up when I was out cruising in 90 degree weather. It was a long ride home that night. I keep a spare in the glovebox now. Thats the only thing I don't like about electric fans. It does fit a standard 65/66 radiator perfectly.

OK I'm going to try the Derale# 16926
I got the new radiator, and water pump in. Just need to install the fan. I sure hope it cools better Side note just in case any of you ever wondered. I weighted the stock water pump and the copper brass radiator,and compared it to the new aluminum radiator and edlebrock alum water pump. The aluminum parts are 15 pounds less the stock parts did. Not a lot but if they weight less and work better it's a win/win. ------------------

If you plan on mounting it directly to the radiator, these METAL mounting rods work very well. There are a total of eight rods, two at each corner, and the fan has holes built into the shroud for these to pass through. Near the bottom. Derale # 16743http://www.derale.com/electricfanaccess.shtml  Before mounting the fan to the radiator, I also took some 1/4" wide adhesive backed weatherstripping and stuck it to the fan. This both seals it, and cushions the mounting points. Highly recommended. Be sure to spring for the adjustable switch w/probe that screws into the water jacket and the metal rod mounting kit (if you plan to mount it mount it in that fashion. Good Luck!

Hi I have just read that Flex-a-lite has a new product 16" high-performance, low-profile electric cooling fan that is as low as 1.25" deep. Might be worth a look, they are launching it at the SEMA Off-Road show later this month.------------------

Steve, to late I already got the Derale fan. But let me know how it looks.Mike, I did get the adjustable switch w/probe. I don't like the way those rods look, so I'll come up with some kind of brackets for it. ------------------

Ron,
I didn't like the look of the rods poking thru the radiator either. So, if you look at the fan you will notice 2 slotted holes on opposite sides. I used those, turning the fan so that they were on either side of the radiator. I used hex head bolts, and placed them into the slotted hole. Then I made an L shaped bracked for each bolt, and bolted the L shape bracket to the fan shroud. Then I fabricated some sheet metal brackets, and made them so they spanned the distance to the existing locations on the radiator support to bolt the fabricated brackets to the support. Looks pretty good, and works well. The fan does not move at all. Probably took me less time to do it then type this long winded description!

Mike, that little fan really SUCKS! in a good way.  With the new 3-1" row fluidyne radiator,edlebrock water pump,180 T-stat,and Derale# 16926 the car did get to 195 the other day. That was after stopping at 3 real close together stop lights and it was 95 degree's out. I was hoping to see it stay at 180-190 no matter what? ------------------

Stop and go traffic in 95 degree weather, and the car got up to 195 degrees MAX.... Well, for a 351W in a 66 mustang using a stock dimension radiator with a tiny 16"x16" core and top to bottom tanks, that's not too bad! Heck, most cars' thermostats don't even open until the temp reaches 195 degrees. If you wanted it to run arctic cold in 95 degree weather, you'd need to install a WIDER, cross flow radiator. (tanks on the sides) You get MUCH greater efficiency from making a radiator wider, than you do from making it thicker. Plus, cross flow rads are more efficient than ones that flow from the top to the bottom. Anyway, that fan is a high rpm screamer. It's made for pulling hard loads through thick radiators.... and it sounds like your radiator is THICK. With thick radiators, the fan shroud REALLY needs to be sealed to the core, or the air will simply take the path of least resistance, and flow through the cracks instead of through the core. I used adhesive foam weatherstrip to seal the fan to the radiator. I stuck it to the shroud, then placed it to the radiator. It sealed great. Good Luck! ------------------

Mike, if 195 is as high it goes I can live with that.
Just not sure how much more it'll go up from there?" With thick radiators, the fan shroud REALLY needs to be sealed to the core, or the air will simply take the path of least resistance, and flow through the cracks instead of through the core. I used adhesive foam weatherstrip to seal the fan to the radiator. I stuck it to the shroud, then placed it to the radiator. It sealed great. " I already did that too. The fan is sealed to the radiator core. I also went around the sealed all the area's around the radiator support from leaks,so the air is forced to through the core.
After using the black magic fan for years. I can say that this new Drale fan kicks it's butt! ------------------

Now as for the cooling problem. What else can I do?
I run a 20/80 mix antifreeze to water. A real good eletric fan sealed to the radiator with a shroud. A 3-1" row alum radiator. New E-brock water pump. Hose's are all good motor was rebuilt less then 2000 miles ago.
On the way to the track driving with the outside temp in the high 80's and the motor at 3000rpm the car got to 195 and stayed there. After about a 45 min drive. We turned off the highway and the temp bumped up to 200. Once we got to the track we had to sit in a line for about 20min. It got to 210 with the heater on. Let it cool for an hour. Made a run took about 20 mins to get to the line. Car was at 195 and on the ride home with the outside temp in the high 60's to low 70's car never got over 180. Unless you floored it then it would jump to 195 and cool back down.------------------

Here is the fan i got, it works like a champ so far. It's sucks pretty hard and is quieter than others I've seen. Fits stock rad. in 65-66 Stang's perfect. Didn't have to pay hundreds of dollars either.

interseting stuff, but 195-200 to me is awful hi temp to deal with.
i;ve cut down the Taruus shroud to fit my rad & it actually works out that it will bolt onto rad bolt mounts, it also has 2 speeds, 1 low speed which is like a Tornado & a hi speed when you hit AC,which you need to use a Hayden/imperial controller for 35 bucks to put hi speed on at ,say, 190.
For a investment of $20 for fan, $40 bucks for controler its worth a try.
otherwise its permacool or Derale I guess
