I'll be updating this thread with pics, descriptions and how-tos as I progress with this mod.
The radiator fan is a bit bigger than the stock fan, but with some tweaking and some custom bracketry, and some wiring work, I'll have a fan that pulls approximately three times the air that the OE fan pulls, cooling the car faster and more efficiently.
I bought the fan today, and plan to do some work on the car tomorrow.

Don't you already have the much more powerful then stock Ford Taurus fan?
Negative... I had been talking about it, but never did it...
The Taurus fan uses a smaller motor than the Mark VIII fan... At high speed, the Mark VIII fan moves as much as 4500 CFM, WITH the radiator in front of it... Most aftermarket fans are rated without a radiator or other surface in front of them... This thing will draw as much as 80 amps on startup, and at full speed will average between 32 and 45 amps running...

Do you have or are you upgrading your alternator? Didn't you move your battery up front? That would be the ideal place to use a relay to run the fan and use the original wire harness to trigger it. I can see where this would help, especially for those that still have functioning AC and the air has more parts to go through. (took mine off the car)

I have a 105 amp CS-130 in there now. I am working on fitting an AD244 with the necessary adapter bracket that I am in the process of engineering... And the bracket may be available soon. This will have 145 Amps of output on an OEM alternator. Outputs as high as 300 amp are available.
I have already upgraded the wire between my alternator and my main system to a 4g wire. My battery is located in front, as you remembered. I run a 4g wire to my starter, and then a 4g wire from the starter up to a battery junction block from a Chevy Impala/Olds Aurora. I have an 8 gauge wire to my Fiero OEM power block located above the C500. The alternator wire ties into the battery junction block located next to the C500. So, everything for charging and load runs over the 4g to the battery, and the 8g is more than capable of handling the power the rest of the car will pull.
You are right, I plan to use the OE wiring as a trigger for the Mark VIII cooling fan. I have a 100 amp relay on order from the business next to where I work. I just have to pick it up on Monday. The depth on the fan assembly, untrimmed is over 5 inches.. I need to see if it will clear the front sway bar without any extra effort.. We'll find out soon enough.
And Kris, yes, the stock fan works... Adequately at best... When the fan turns on, I want to watch the temp gauge drop immediately..
My 4.9 and 3800 Fieros haven't had any cooling problems (once working correctly), with stock V6 radiators and fans. But since it's because you can, go right ahead.

I don't have cooling issues either... I've just always wanted to do this since I discovered the Taurus and Mark VIII fans a few years back. Someone had one on a classic Chevy, and when he flipped the switch, you could stand 10 feet to the side of the car with the hood open and feel the air blowing around the engine and out of the side of the car in the gap between the hood and the fender... Color me impressed...

Agreed. If you want more cooling, put in an over ride switch. That's what I did and I can sit in traffic when it is over 100F with a same or lower than normal engine temperature.
