Has any one used a electric fan instead of the one off of the alternator. And if so what CFM would be the best. For 2387 stroker......

Finding a 12 volt electric fan to move as much
air as a stock fan would be near impossible.

Yea a lot of us down here in bama run then on our buggys they
work pretty good

You use them in place of the fan in the shroud to cool the engine?

No. He's thinkin ab an oil cooler.
It's been talked ab fabbin up some to blow straight on top of the jugs n heads. But probably wouldn't save much hp. Unless you was makin a drag car

I have an external oil cooler and the fan in the shroud came apart so instead of putting another one back in i thought i would go electric. Just wondering what CFM the factory one would put out.

Bad idea,I have a friend that had that done, that was a very hot unhappy engine.

I think it would work great. I have a dual fan on both my water cooled v6 buggies and they pump some hard hot air out. Pull the air UP thru it with a home made shroud. (dual fans lying face down) The shroud is the difference . With a shroud and a vacuum every crack and cranny has moving air. Blowing down, hot spots can hide.(such as under your jugs and heads)(more area of your case will love it). My w/c's stay on 160 degrees no matter how you drive and my oil temp on my a/c is 190-200! Run 2 positive wires and 2 negs to the electric motor(INSURANCE). Maybe an inline fuse on 1 pos. line for trouble shooting. Wire the radio in series on 1 of the negatives with your radio so when both circuits are bad, Hank Williams quits ...then something is wrong in Dixie! Wire it straight from the batt with a Autozone throw bar switch direct from the batt. No toggle switches to forget to turn on or go bad. Buuuuut don't be running around on a dead battery too long. Run a volt meter and make sure it has 10.5 minimum to 14. The alt. will work pretty hard til your coil will barely work.Also, I hear they make an aftermarket LARGE stock vw fan so that might be a better option for dependability. You can't win for loosing... If you have 2 whirlwinds it will choke your alternator down any way.

Just get a welded stock fan and be done with it.

Ditto

Typical dual port fan produces 1270 cfm at 4000 rpm.
One would be hard pressed to find an electric fan with the CFM of the VW fan.

I had a friend who had a fan such as this mounted to the cylinder head tin on each side of his drag motor. this was a drag car and ran for 10 minutes at a time. I don't know that I would recommend that for a motor that has to run and be beaten on for extended lengths of time.

I know we keep beatin this subject, but I once heard somewhere that fast moving air or water don't get as good of a chance to do the molecular transfer of heat from metal to air. maybe I am confussed but I would like to try that big aftermarket vw fan I've heard about.

I rode with a guy who had a VW trike with the ring gear flipped and had the motor facing forward without any fan/tin. Also know of a machinist in Western PA that mated a VW to an old BMW cycle, again no fan. Riding down the highway isn't the same as puttering through the woods but the electric driven fan doesn't seem that farfetched? JMHO

Here is the spec of what i have found I like the amps and the CFM from what I here is more then the stock one.

8 inch high performance universal electric radiator cooling fan. The fan is a 10 piece flat blade type. The motor is reversible and the fan is 12 Volt 3 Amp 2860 RPM and 1700 CFM. Four point mounting bracket kit. The high torque motor features sealed ball bearings and fully balanced blades which insure low noise levels and a long life of smooth operation.

what about the porsche style fan?? i know its a lil pricey but that thing looks like it will move some air.. looks cool too
