Ok, so the time has come to replace the belt driven fan with an electric one. I just want to know if anyone here has suggestions as to what I should get. Thinkin a dual fan, but if I can get away with one bigger fan I will do it to save money.
What do you guys think?
Sell the 2002 Off for part money and to replace it buy a 1st gen eclipse with a turbo then add a few new parts to the cougar.
not sure about fans all i know is my old one cracked so i get me a nice new Flex-Fan its better than stock.
I bought a "Black Magic" I think it's called, from a Cup team. I remember looking for info about them afterwards, and they pull a lot of CFM.
lol no thanks, the eclipse is my daily driver and it does a good job. Also I like the 3G body style and you can always through a ripp supercharger on it and get up in the 320 HP range easy.
I have some info I would like to share with everyone
Mark VIII Electric fans that came stock on the car flow around 4000 CFM! Yes I am serious! Also they take a lot of amps to run so if you get one I would suggest a new alternator to power it. They also fit right in to our cars.
I have been reading and it has become a very popular mod in other makes. I recently read about people putting them in their Corvettes.
The best part about them is they are really cheap on Ebay. Around $60-80 bucks!
Carl, I have a few tarus E fans if you need one man.
thoes mark 8 fans can draw upwards of 80a. I would use either a taurus or v6 mn 12 fan (very cheap) a new one thats the whole assy is like $119.
You can't go wrong with either a Taurus or a MarkVIII Fan. They are relatively cheap and pull more CFM than most aftermarket units. I have the Taurus and even on low speed it is enough to adequately cool my TC. You should plan on upgrading to a 3G as well.
Did you get the 3.8 fans, or do you still have the (not desirable) 3.0 Fans?
The Mark VIII fans draw ~40A. The MN12 fans draw around 30A, the Taurus fan pulls ~35A.
Flow --> MKVIII>MN12>Taurus>>Black Magic
I have the 3.0 fans for mine, but I can get the 3.8 ones too. Juet let me know what ya want.
i bought my mark VIII fan for 10 bucks!
these number are for current draw while running. these fans pull between 80 and 100 amps at start up, thus you need a relay rated at 100 amps at least when using these fans. either that of get a fan controller that has a "soft start" feature. even then these fans will pull around 40amps on start up.
I got my Taurus fan for like $20 or something at picknpull. It does a splendid job cooling my 302.
Did I state otherwise?
A 75A relay will work fine.
Years ago I had an '86 TC that I used a honda civic fan to suppliment the stock fan. I tied it on w/trans cooler ties & just reversed the polarity. Just about anything will work.

you got that backwards.,, and very illegal. YOU rate fuses/fuse links/ relays ect at 80 to 85 % expected max duty cycle amperage draw just as you would if you were to add a breaker in your home electrical box. We "under fuse" for a reason, we never over fuse for obvious reasons.
in your case you would have a relay in place that would survive wiring melting and a fan catching on fire before the actual "FUSE"(ie-relay) ever failed.
the relay is suppose to be the weakest link in the circuit aside from a possilble fuse in line with the coil.
The "instantanious" current draw you describe does not really count in this cirspoogestance because it only peaks from the point of instant power then quickly declines in draw. If a circuit breaker were used instead of a relay, perhaps the breaker would thermal or trip but relays deal with this momentary fluxuation with a little more patience than a fuse or a breaker would.
Over time, the relay is suppose to be the failing part. I dont know off hand what the relay amperage is on the M7 but i would not be the least bit surprised if it were at or about 35a. Thats a fairly high rating in general for vehicle applications.
then again, since i dont know the m7 relay size, i could be wrong.
Your "soft start" feature you mention is probably just an RC time constant combo that delays the fan coming up to speed quickly. IMHO,, this this would increase the time it takes for the fan to overcome the spike and increasing current draw for the first 1/2 to 1 second thus keeping you a max current draw for a longer period of time. Im not sure i like that idea,(unless its wired so the capacitor takes the beating).
there aint no way in hell a m7 fan relay is an oem 100 amp relay. If that were the case, you would have 6/awg wiring comign out of the relay.(depending on loop length of the power and ground distance)
