I just came back from the bank today and while I was stopped talking to a friend B) (I had the car running and was standing on the corner) the car started to plume smoke . I looked at the gauge and she was overheating... I didn't even notice that the fan wasn't running. The antifreeze was pouring out the overflow canister . I put the heater fan on full blast and drove home :drive: . She cooled down quick, no harm done. I checked for power and everything is OK . It got dark so I wasn't gonna take the fan off, I'll do it tomorrow. I wonder if the fan motor went or the switch went :scratch: ? Anyone else have this experience with the FLEXALITE BLACK MAGIC FAN? Thanks

I would test the fan first with jumpers wires from the battery.
Positive on one and negative on the other.

not sure how to test switch...............

Show me a pic of the fan, That must of stinked!

I don't have a pic of my installation, but here is a link to FordMuscle.com doing the installation on one of their project cars. It is a great improvement to the cars cooling and it supposedly adds approx 25HP... you can feel it.

Here is the link:

Flex-a-lite installation

WOW, 25hp. Thats alot for a fan. There should be a warranty, call em up and complain. Check the Battery, alternator, and the wiring. Good Luck!

Sorry but I have to say that a 25HP improvement claim is the most BOGUS claim I have ever heard(or close ). An electric fan does help eliminate parasitic loss from a clutch fan but NEVER 25HP!!!! This is nothing more than an advertising gimmick and they are probably repeating what the manufacturer told them.

I personally prefer using the 94-up Mustang factory fans...the move A LOT more air than the flexalite but you really need a 3G alternator conversion to run one.

Please guys...DON'T believe what you read with HP claims....if every part you put on the car delivered the advertised claim then you would make 500HP naturally aspirated with bolt-ons....not gonna happen. When they advertise things like this you have to take them with a grain of salt and consider what their testing standards...if any...were.

I thought that HP was a bit much, I know they add 5hp plus cooler air, but 25hp seemed out of wack

JR333

I know what you are saying... A BIG example is underdrive pullies, I don't feel a difference at all... but the article from FORDMUSCLE.com that I posted says 25 HP gain... I was just repeating what it says... check it out...

svopaul

I read that link you posted....IMO it's a gross exageration Marketing technique used to increase sales.

There is a benefit of electric fans no doubt but not ever resulting in a 25HP increase. I'd love to see/pick apart their "test results" if any that shows this...

Just remember to take advertising with a grain of salt....As an example you will see advertised gains on Cold Air kits...their testing was probably on a stock car that still had the air silencer which most people have already removed so installing that kit on your car that already has a K&N panel filter and air silencer removed will net you less HP gains over their testing...but it looks good on paper/advertisements when they do it that way

Regardless of that example I still see no way on this earth that they could prove under any condition a 25HP gain....unless the first test was done on a 100 degree humid day and the other on a 50 degree fall day with no humidity....but you see my point on how they manipulate numbers

Fordracing200

Did u call the company yet? Is there a warranty? Run a short belt at the track and underdrive pullies and u will feel the difference. the underdrive pullies only add like 5rwhp, so don't be concerned if u can't feel it. there is NO way the pullies add 25hp

SATURDAY IT IS GOING TO BE 60 DEGREES IN NYC SO I AM GOING TO HAVE A CHANCE TO LOOK AT IT. I AM HOPING THAT THE SWITCH GOT WET WHEN I WENT THRU A CAR WASH... FINGERS CROSSED.

Fordracing200

I would do a dyno to get the HP readings correct. Pullies dyno 5rwhp increase. What switch got wet? there is a few of them in your car

JR333

Electric fan switch

JR333

FIXED THE SWITCH TODAY. FLEXALITE HAS AN INTERNAL ADJUSTMENT ON THE THERMASTAT SWITCH. THIS TINY SCREW CAME LOOSE SO THE CONTACTS WERE FURTHER APART, THUS THE FAN WAS NOT KICKING ON. I ADJUSTED THE SCREW, PUT LOCTITE, AND ASSEMBLED THE FAN AGAIN... RUNNING COOL NOW... THANKS ANYWAY PEOPLE!

Electric fans make a difference not in horsepower from engine but in power to rear wheels.It reduces parasatic (sp)loss which is power to drive accessories.

If a motor turns 280 at wheels the fans can make a 10 -15 hp difference at rear wheels.

I know when I switched from a factory ford fan to an e-fan I could feel difference in seat also and got .07 in 1/4 mile.14.40 to 14.33.Which equates to about 10 rwhp in same car with no differences.I went from aod to t-5 and went from 14.32 to 14.14= about 20 rwhp. Changed to Flaming river manual steering rack.Went from 14.14 to 14.09.about 5 rwhp

Lets say a motor turns 250 hp with no accessories it still produces 250 hp just only puts 180 to rear wheels after fan/ps/ac/tranny rob hp needed to operate these.If you eliminate these power robbers you get more rear wheel horsepower. Your engine does not make more power. It just has less accessories to drive thus putting more power to the rear wheels.In my example it would equal 250 gross hp yet 210 rwhp compared to 180 rwhp from factory.

Similar to differences in rear wheel power from an automatic to a standard.

Same engine just more usable power.

I feel efans =5-10
underdrive pulleys = 3-5
manual steering =3-5hp
manual tranny = 15-20hp

Check your fuse that runs inline with fan kit. If ok check your fuse holder. I know some e fan kits have had an issue with the fuse holder getting hot and melting where it causes the fuse not to keep a connection to complete circuit. Also check your relay. I had one get hot and fail . Replaced at local parts store and no issues since. Very seldom will your fan motor burn out,even when wet. I have a set of e-fans on my supercharged 4x4 plow truck and use year around in all weather types with no issues with fans failing. I had a fuse pop once and lost a circuit breaker once.Otherwise flawless. Even in 98 degree weather and 30 below weather. Rain snow or sun no issues.

Rus, you are correct but your numbers I feel are off.....a dyno can give you accurate numbers. I don't feel that the fan difference yields that much to the rear wheels...but I have not dyno tested that so I don't have any hard data.

I CAN tell you though that we did a 5 speed conversion on a 94 GT and picked up 40 Rear wheel HP over the Automatic (Dynojet proven)...so you are not giving enough credit there

rus

I am true believer in the efan power increase. I felt the power increase and my numbers did get a little better at the track with no other changes. I would never claim 25 hp difference but feel 5-10m is realistic. I will check to see if I can find some of my other racers with dyno numbers before and after their efan install.

Rus

Fordracing200

Russ is right. I have seen those same power numbers come off the dyno in magazines and from people at some other sites.

svopaul

I am by no means disputing that electric fans don't free up HP....remember, "FREE UP" not "MAKE"....5-10 can be realistic however I don't think much more than that would be a realistic figure and especially not 25
