my fiero fan wasnt cutting it anymore, plus i needed a shroud for it. went to the junk yard, the guy opened me the door to the fans and told me taurus fans were great for 5.0L mustangs. I took one, checked to see if it fits and the 2 driver side hole on the shroud matched the radiators side holes. 2 wires, same as the fiero but bigger gauge, and voila. no more over heating during traffic.!

If you can find the 3 wire, 2-speed fan from a Taurus 3.8L it's considered the highest CFM fan in a factory vehicle (hotrodders use them to cool 454s). Same was used in some 3.0L Tempos, 3.8L Sables, and Lincoln Mark VIIIs. The 2 wire, single speed Taurus fans are the same with no high-speed level, probably just fine for the sevens.
Keep in mind! These Ford fans are MASSIVE power hogs, and the wiring and relays must be big. Usually people are running 40 amp Bosch relays (the fans draw about 33amps at speed, 75+ amps at startup). Use good 10 gauge wire, and make the runs as short as possible, with good quality connectors.

Nice info Pazuzu!!!!!
So how do you use the 2 speed option? Also, what's the best way to trigger them? Should I just get a temp switch from Summit or something?

Autozone has temp switches, Flex-A-Lite sells temp switches all over, or find one in a boneyard vehicle. Use the switch to run "ignition" power to the low side of a big old relay, run battery through the high side of the relay, done. The temp sensors come in two flavors. Either a threaded plunge sensor that you use inserted into the water flow itself (either drill and tap a hole somewhere in the metal water line, or cut the rad hose, and put a bunged insert in there), or a probe that gets shoved between a couple if fins in the radiator, or taped to the hot inlet side of the radiator. The 4wheelers also often put a kill switch and indicator light on the system, because when you make a deep water crossing (crossing a river) the pressure of the fan blades hitting the water will shatter it, so you kill the fan before you go in the drink. Simply a kill switch between the ignition power and the low side of the relay. Dunno if a Seven would need anything like that, but ya never know. At least a 12V LED indicator might be nice, so you know that the fan is actually spinning while you have the tunes cranked (wouldn't want the fan to die while your racing and you don't know it!!!!!)
