440 electric fan

[old guys rule]

gunna try again. anyone have experience cooling a mild 440 with an electric fan on the street only? looking for a cfm figure. thanks, Dave

There was a post I saw on FB where someone took an 08 Challenger fan and installed it in a b body with minimal trimming. Supposedly close to 5000 cm.
I have a dual Flex A Lite that is around 3500-4000 and it has kept my 440 pretty cool in the heat of summer.

Here's the problem, there are companies who advertise 2,500, 3,000. 5,000 cfm e-fans. 99% of them are BS. If you have the room between your radiator and w/p pulley, get a Lincoln MKVIII e-fan and trim the shroud to fit. Auto manufacturer fans cannot be beat by any aftermarket company. But the good (high cfm) one's are generally 5" deep. There are 2 versions of the MKVIII fan, 2 speed and 1 speed. I can't remember which is which, but the sought-after ones are the 97/98 model yr fans. Lots of write ups about them. Here's just a couple examples

Thanks much for the info. One thing that worries me yes I don't believe my car's electrical system will handle a 130 amp alternator. It's a 63 Dodge B body

Real world CFM Requires Amps. Unless it's a brushless motor. Spal fans are probably the closest to putting out the CFM they advertise. And they draw amps.

That ain't happening in a typical late 60's/early 70's b-body with a big block and anything approaching
a 3" thick radiator.
Heck, it's so close on my '68 with Griffin 3" thick "Exact Fit" radiator and the 440 that I can't even run
a fan clutch (no, not even the thinnest "Jaguar" Hayden one).
I have a direct drive 18" 7-blade steel fan with a small spacer in there now, in the factory shroud (that doesn't
do much).
I'd like to know what the cfm ratings are in some of the late model Mopar stuff running hemi's.
Every one I've had sit right on the thermostat rating and never get any hotter no matter what.

I have 2 Spal fans cooling a mild 440 in my cuda. I hate the noise they produce.

I'm running a Flex-A-Lite Black Magic Xtreme model 180 15" reversable (pusher or puller) electric shrouded fan. It has a 18 amp draw moves 3300 cfm. I'm cooling a heavy built 440 with a 871 blower which adds more heat and it cools it with no problem unless its 100 degrees outside in which I wouldn't drive the car then anyway. I got it mounted as a pusher because of the supercharger but it can be mounted as a puller also in that case it would work even better of course.

That's not cooling the engine just fine then. All American made cars were designed to keep the engine cool in the southwest, 110-120 outside temps. Where I live it gets 125. I won't own any kind of vehicle I can't drive in this heat. And if your fan is only drawing 18amps, it's definitely not pushing/pulling 3,300 CFM.

I totally agree, that's why I told the OP on his original thread to use mechanical. And a stock 440 w a single row aluminum of 1.25" 26" wide will cool just fine. I have exactly 3" between my pulleys and my 2 row radiator that is 2.75" thick. No fan clutch on mine either. Keeps my 496" at 174 on the interstate, 194 in stop n go w factory shroud in 125° weather w the a/c on.

I think my duals pull 25-28 amps and if i rember correctly are around 3500 cfm.
Something that people arent mentioning is that a single fan often has clearance issues with the water pump pulley. Thus the reason I run duals, allows the pulley to be in-between the motors
There are a lot of factors that can affect performance and heat gain/dissapation, straight bladed vs curved, water wetter, vs antifreeze, leaded fuel vs unleaded fuel, advanced vs retarded timing.
Good luck!

Look it up, it's on the spec sheet with the fan, 18 amps 3300 cfm. as for the cooling well as we all know horsepower makes heat and a very strong built 440 with a 871 blower (blowers make heat also) making just over 900hp is going to be hard to keep cool on the street in traffic. I challenge any cooling system to deal with that on a 100 degree day!

I'm not 900hp but then neither is yours cruising on the street light to light, we'rebarely using 200-300 hp cruising around. You are probably 9:1 CR w a blower in a 440. I'm 10.5:1 610 hp on 496". I lived in Vegas for 23 yrs and many friends w blown/turbo 1000hp cars running on the streets just fine in 110+ temps. As for Flex a lite Black Magic fans, the don't draw anywhere near what they claim. As an aftermarket e-fan, Spal is probably the most legit on their ratings. Compare the 2 cfm to amperage draw. Just noticed you said it is a shrouded fan??? If you are using a shrouded e-fan as a pusher on the front of your radiator, you are getting "NO" airflow. It is a huge restriction!! No shroud on pusher, yes shroud on puller.
