Getting rid of stock Fan shroud, and looking for the best electric fan out there with the best CFM or best cooling results.


I'm doing a comparison.

Be Cool universal fan
$349.99
pulls 2,360 cfm at only 12 V



------------------------

Flex-a-lite Black Magic Electric Fans
$182.99
2,800 cfm of air






------------------------

THIS FAN SUCKS DICK

Mr. Gasket Electric Cooling Fans
$81.95
16 in. fan, 2,000 cfm at 1,900 rpm, 11.4 amps draw
---------------------------------

SPAL FAN

Have seen them as cheap as $79 for 16 inch.

They claim, 2,700 CFM +


Anything else out there? I might try the SPAL fan. I have heard good things about them in the Car magazines...

----------------------

Street Rod Stuff has some good Radiator / fan + shroud combos. They have some pictures too.

Anyone have a finger chopper?

 

Perma cool finger chopper... great price, low amp draw, great airflow...

If you can find one not on backorder that is.. *sigh*
Still waiting on Jegs to get some....

 

anybody know how much does stock fan pull?

 

Enough.

 

I'm happy with my Flex-a-lite Black Magic Electric Fan #150. If only It covered more Radiator surface. It covers about 70% FYI.

 

I heard the stock fan + shroud cools the best than any other E-fan out there. Is this true?

 

*****anybody know how much does stock fan pull?****


yes

 

The Flex-a-lite sucks like Star Trek V but it is LOUD AS ****. Once it kicks in you cannot carrying on a normal conversation beside the car...


Save yourself some cash and grab a Fiero fan from a scrapyard. I've yet to hear one complaint from an RX-7 owner about it. I've got one in my own 7, connected to a Flex-a-lite temp switch, and it works perfectly and isn't too loud... Installation is relatively easy and straightforward.

goto to the junkyard and get one off a Saturn works just as good, fits, and i only paid $10usd!! hehe!!

 

I've also heard that the stock fan is best.

 

i've seen it.. yes its a bit loud.. especially with the hood open.. but at least you know it's doing it's job right?

personally i have a e-fan from a 88 2.0 OHC gm car.. they used the same shape/mounts on about.. like.. well almost all their cars.. lol..

it covers (roughly) the same as the flex-a-lite. 70% ish.

it was cheaper, and the car runs nice and cool with it.

if i didnt get the scrapyard special, i would have gone with a flex-a-lite after seeing it in silverrotor's car..

btw - a heads up on the junkyard fans - have fun making proper rad mounts for it! lol takes some fabrication, but you can make decent brackets..

 

yep, as long as you're sure it's working at 100%

but the electric fans definately compete well with the stock fan.. some fans are better than the clutch fan, but at the expense of power (amperage draw).. since FCs have crappy alternators to begin with, i STRONGLY suggest upgrading your alternator or at least making sure you alternator is in good shape before you do the e-fan mod.

personally (since the e-fan cools just as well) i chose the e-fan mainly to open up the engine bay..

 

What's with the electric fan bandwagon? I see a new thread pop up every couple days.

 

SUMMER IS COMMING! =)

I am mainly switching over to an electric fan because I hang around 4K + RPMS all the time in the canyons.

Thanks for the input guys. I think I'll order a black magic fan and do my best about covering all the surface area on the radiator for the pull draw....

 

My FAL BM fan keeps the opposite side of my radiator ( just the area that the fan covers on the opposite side ) cool to the touch pretty much all the time. Its an awesome fan.

 

I am personally partial to the setup found here.

That's what I am going to look at when I get around to installing an E-Fan.

 

I got my fan yesterday out of an escort (91+)
It has 3 wires.. ground, low speed and high speed. I'm going to hook it up here in a bit. It seems to flow a lot of air!

 

That's the wrong reason to change to an e-fan. The fan is only there for low speeds when there's not enough airflow to cool the radiator. At the sort of speeds I assume you're driving at to be at 4000rpm the fan will be doing little if anything. An electric fan will make no difference.

 

It does if I have a front mount intercooler.

I was also thinking of getting a bigger radiator. That might be my main problem that needs attention.

 

with the huge radiator I have, my black magic never has to kick on unless I'm sitting at idle for more than 5 min. but seriously, if you can hear your fan over the exhaust...you need a louder exhaust

 

cbrock. What radiator are you running? I think I might upgrade the radiator & Efan at the same time.

 

I'm running a Howe double pass 28x19x3 with the inlet and out let on the pass side. Won't work with AC though...and barely has enough run to pass the oil cooler lines and wiring harness on the drivers side. It was 269.00 (summit) and I had to have a nipple welded on the tank for the heater core return and some L brackets to the sides for support. Here's some pics

wow. cool. I'm gonna post your pics. Looks good.

What kind of temps do you see? How difficult was the mounting? What kind of radiator hose bend is that?

I think your setup looks like it would performe the best overall. It's artwork! That radiator is huge!

 

The hose is that stainless flex hose in summits catalog. It's rather expensive at $90.00. But that includes all your clamps and adapters. You could do it with rubber hose if you like. The mounting was easy. Have the tabs welded on so that it sits on the frame rail. Drill and tap frame rail for some nice stainless cap bolts and you're done.

Temp on the highway is between 165 and 175 (uphill) at idle at a light it might climb to 180 and if it idles a really long time, it'll kick up to 190 at which point, the fan turns on. Mind you, I have a stock thermostat

All of this is preparing for the greddy front mount that's on the way.

 

Very nice. Are those Magnecor wires I see? I'm running the 10mm Magnecor. Big difference over the MSD 8mm I was running.
