On my dad's 88GT his stock fan is cracked.So we are going to replace it this summer.Which electric have guys used and which ones work the best.His car gets driven alot in traffic and on the highway.Or would you just put another stock fan in?
My pops wants the electric fan to pick up a few more HP.

I've heard really good things about Flex-a-Lite's Black Magic from a few 5.0 racers. Haven't heard much about them on the street, but they sure do move lots of air.

If it's cracked, I'd change it now before it grenades. If you've even seen a fan when it blows, it's not pretty. If you're looking at it when it goes, you won't be, either.

Lincoln Mark VIII fan. New one from Houston Performance or grab one from a junkyard. The Mark VIII fan flows CFM's outta this world and would keep the hottest engine cool, even if sitting in blistering heat at a stoplight.

No offense to Flex-a-lite, but the Black Magic fan is basically an OEM replacement, not an upgrade. It will keep your Fox cool, if you live in a temperate climate. If you live in a hot region of the US, might as well stick with the fan that came on the car. Especially if you're doing it to free up horses, 'cause it only produces a negligible diff on the dyno.

Info from another board I often frequent, consider a spal fan. They move up to 2880 cfm. But the trade-off is they are nosey. If you do a search for "spal" on the internet, lots of places sell them.

i would go with the black magic electric fan. it of course releases drag on the engine and continues to run after the car shuts off, while the factory clutch fan requires the engine to turn.

My dad likes the idea of the black magic being a bolt on.I've read they pull more air then the stock fan and fit good too.
But I've also read about alot of people who have had them fail.I don't want to take anychances because he takes his car on alot of long road trips.His car has never run hot even with all the org parts.He would like to free alittle power.I tell him to get some gears and put the stock fan back on.

I have the black magic fan on my car. I put i there for the same reasons you are thinking of getting one. My stock fan was cracked, and I needed to replace it. I've seen flex-a-lights come apart, so i went with electric. The fan is OK. My motor was stock, and I had a 180 deg thermostat, along with a new water pump and a 3core FRPP radiator....in the summer, the fan can't keep the car cooler than 200deg. It usually sits around 210 until I get moving. It does run after the car is off, but ONLY because I haven't wired the turn on to the ignition switch to prevent it. I'll probably do that later. The fan does free up some power, enough that I noticed, but only while it's NOT running. You still get loss through the alternator. It takes almost as much energy to spin that fan as it does the stock unit, and that power has to come from somewhere......be it the belt, or the alternator. For the track, I just kick up the thermostat on it to prevent it from comming on as quickly, but once it comes on, you can definalty feel the drain. It's not a bad unit, and as long as he keeps the car stock and avoids really hot climates using and using the AC in traffic he should be alright. Otherwise, I would look for something that flows some more air.

Fishtail,sorry to hear it does not work better for you.But thanks for the heads up.Thats what I love about this site.Lots of honest people willing to share whats does and doesn't work.
I'l tell my dad to go with a new stock fan.And some gears for alittle more pick up.

I use a BM fan myself.I don't have a cutoff switch installed yet,but it running after the engine is off don't bother me at all.I get wonderful temps(although I use a FMS 3 row) but I am very happy with it.

The current consumption of a fan that moves a large amount of air is high.
Few mention this fact and most don't want to beleive it still requires power from the engne to operate. It's not free hp as some magazines would have you believe.
The Lincoln Mark VIII fan draws 140 amps to start. This is far beyond the alternator capacity on most Mustangs.
Alternators will draw 10hp per 100 amps out of the engine so a previous post reply seeing the differenct between when fan is on and off, shows this up.
When one gets into the installation of a correct sized fan, there is more to it than meets the eye, such as alternator and battery size. Then there are those who want to run under drive pullies and make the problems even worse.
Stay with a new clutch fan and be farther ahead on the street. Much less cost and hassle.

I know racers who put i switch on the alt wire to cut power to it and the electric fan as well so when the race it they shut it off for the run but you battery better be fully charged to do this. then after the run they flip them back on to cool and charge. rember 10-14 seconds of not charging is not going to hurt your battery or put a strain on it but if your battery is weak and you have a lot of electronics on it,it can hurt you as the load demand is higher..as far as just shutting off the fan during the run you dont need it running at high speeds anyway, just turn it on at the end of the traps and on the return road..Bruce P.ss just in case you where wondering why someone would cut power to the alt during a run is no electricty to excite the alt no load or the pull it just free spins..
