Not to jack the thread but has anyone seen numbers on how much it takes to run the fan when the clutch is engaged?
Something to consider:
Your engine only needs a fan/fans running when you are traveling less than about 40 mph.
After that, incoming air does the work. (Assuming you have all the proper airflow directionals in place, such as the air foil under the radiator support or any other stock panels to direct air.)
The E fan saves very little power contrary to popular belief.
Is it worth it? IMO not unless you have bolted on every other thing first. By the time you set it up, it's like $400, to get 5hp, not exactly the most sensible way to spend money.
Imagine this, guys spend this money on the E fan setup and they get their 5hp, that same $400 could have been spent on better heads gaining 20-30rwhp more than their gt40p heads.
No logic in it.
It's a terrible bang for your buck mod, not only that, it's unpredictable because seems everyone likes to use different fans.
Maybe it's just me, but I can go to the yard and get a monster fan from a Lincoln or Taurus for 10 bux, and then wire it up with a $25 adjustable thermostatic switch. All it takes is some time and fitting. Definately not 400 bux.
I have done it before with a $7 non-adjustable thermostatic switch, but they were unreliable.
I think he means with a good variable speed fan controller, and a 3G alt conversion as well.
I agree though it can be done for cheap, and most of us had the 3G conversion done already anyway.
The stock fan is very efficent and pulls more cfm then most electrics...
What thermo did you put in, what radiator do you have.
IMHO, a good percentage of 94's increase in HP is because they got better software for the EEC. The Fox software was 20 pounds of **** crammed into a 10 pound can. For the Foxes, Ford wanted to save their $5->$10 per EEC by staying with a small PROM.The 10HP gain that the 1994s got over the 205hp 1993s was attributed to the electric fan.
I installed an electric fan because #1 my engine would take to long to get to operating temperature with that mechanical fan blowing cold air onto the cold engine, even though the thermostat is closed at startup and should warm up quick, my engine didn't. #2 my engine temps went way too high sitting in virginia summer traffic with the mechanical fan and automatic trans, with the electric fan i can sit all day long now in summer heat. #3 I like when its cool out the electric fan stays off at cruising speeds. My 460 tbird would overheat in summer traffic with the mechanical fan and built c6 trans, with a dual flexalite electric fan setup i can idle all day long at 198 degrees on the temp gauge. A mechanical fan spins too slow at idle to cool a modified engine in summer traffic so modifiy that engine so you have a reason to overheat.

Also, the 94's got better alternators - 3G. So, less HP loss.
I find it interesting when people in the forums claim that a 100amp alternator takes only x-HP by quoting very basic and simplistic equations. I'm sure that the car manufactures of the Prius, Volt, etc would pay MILLIONS to get an alternator even close to that efficiency.
