What junk yard cars come with big dual electric fans?

Does the 3.8 taurus have duals?

Thanks!

I knoa where you're headed! I tried all summer to cool my 406 with electric fans--I've got a dual set up with a custom made shroud that fits perfectly on my new aluminum radiator. Distilled water flows unrestricted thru the new Stewart Warner aluminum pump. I'm telling you now that if you plan to run cool, electric fans aren't the way to do it. They just won't pull enough air thru the radiator. Maybe if you've got a mild 355 and don't run more than a few laps you can get by...but I'd suggest the mechanical fan.

I understand what your saying about electric fans. But there has to be a way. The NASCAR guys run electrics. They have to because even at 180 miles an hour they cant get air with out a fan.
Maybe thats why those fans are so expensive. Junkyard left overs wont move enough.

From Perma-cool's website:
How much airflow (cfm) do I need to cool my engine?

A four cylinder engine requires 1600 cfm; a six cylinder engine requires 2,000 cfm, a small V-8 engine requires 3,000 cfm and large V-8 engines require 4500+ cfm.\

And a pusher fan is only 80% eff. compared to a puller. Sooo.. you'd need at least a 16" puller (2950 CFM) and at least a 12" pusher (1650 x .8 = 1320 CFM) for a total of 4270 CFM. I'd think a race motor would be comparable to a big block. 2 fans would also pull about 17 Amps, so I hope you're running an alternator or 16V battery. I ran a 12" Permacool fan on mine wired to through a relay to a switch in the car. It helped, but my motor was scrap (pin hole in the block leaking coolant into the chamber) and it can't cool when the water disappeared.

what electric fan did you use??

I have posted on here a dozen times that a fan off a gm products fwd car which is 16 inches will pull more air than any aftermarket fan.

They sell the same fans at Gm perf shops for over 225 bucks.

I get mine at the u pull it type lots for 6-10 bucks. Everyone where I was racing has switched to the same fans in the last 5 years.

I had black max duals, and other expensive aftermarket ones before I tried one of these.

just go get one and test it and youll see!

Actually NASCAR uses the fans for caution laps. when there are racing they dont use them. If they needed all the airflow they could get they wouldnt be taping the grille off.

I have to agree with eljojo I had dual spal 11" fans used cup equipment.I didn't have it as cool as I wanted.Now I have a single 16" flex fan and have had no problems this year with cooling,acually had to tape the grill to get it to run @190 deg.I messed with electric fans and gave up.More than likely you will do the same sounds like a good idea but has some downfalls.Put your money somewhere else.

I've run dual electric fans for years. I run a 355 11-1 hump heads with 202 valves on a 2 barrel carb. and it always kept the car nice and cool. I ran seperate switches so I could turn them on and off as needed. I got my fans off of a Ford Taurus 90 and up 3.8.

Ford has some E-fans the flow some HUGE amounts of air, like the fans off the the late model Mark 8's. I have one on my street car and if I could run an electric fan that is what I would use.

Update:

Found a dual setup off a 95 Lincoln Continental (tank!!), measures 17x30
with a 14 and a 16 inch fan.------->

Also found out that 90's Ford Windstars had duals as well.

I'll let ya know how it works!
Thanks

I dont know where i read this or heard this... Have you ever been on and exersize bike that has a fan on the wheel? The fan is there to make it harder to pedal. This has the same effect when you put it on the front of a motor, it is alot harder to spin, taking away horsepower. If you run an electric fan, this would take that added stress away from the engine, giving you more power.
