I am gonna replace the Ignition system in my F250 with the MSD system recommended earlier, while I am in there I am thinking of installing electric cooling fan(s). Has anyone done this, any recommendations as to brand, size etc.
This will be on HD cooling (towing package equipped) 351 engine.
Any info appreciated.

I put in 2 14" PermaCool electrics...each one pulls 2700 cfm which is what a normal fan will pull at around 3-4000 rpm. Works great...easy install...PermaCool has the most cfm with the lowest amperage...

Bjoern and Slikness thanks for the replys. I like the idea of the camaro fan VS the cost of a new setup (@350-400$) that I got quoted for a flex-a-lite system.
I live in Arizona where it gets 100+ in summertime, is there a bigger electric fan out there that can be found in a wrecking yard?
Slikness how much did your system cost?
It seems I can get the complete MSD system (box, coil, wires, cap, rotor for around $300 so I would like to keep the fan costs sdown if I can. Also got to have the transmission sealed and gonna R&R clutch system while at it. Wife wants a trip to mexico in may with the trailer!
Once again thanks for the input.

I used Flex-a-lite Black Magic #150 on my 78 Ford with 400 and it works great, even when idling at a stop light on a hot Colorado summer day. I plan on using it on my Bronco with 351W as well. The fan itself is smaller than the flex fan I replaced but you gotta remember that flex fan spins the slowest at idle (where the max fan flow is needed) where as the electric fan can spin at max rpm reguardless of the engine speed.

I paid $89/fan plus about $20 for the relay and another $5 for a switch..let's see that's about $205 and they will pull more air than your dual flex-lites...I don't think you can get more fan power for the price...

I went and looked at Bjoern's set up and he's done a terrific job!!! The shroud will help utilize the full air movement of the fans across the radiator. Bjoern, it looks like you put your thermostat in the return line to the engine?? Most of the thermostat controls are set to come on using the hot side (upper radiator hose) and come on between 170-190...I also prefer the thermostat that screws into the water passage in the intake or into the thermostat housing...I used one of those that mounted into the hose and could never get the hose to seal!!! I finally just mounted the sensor to the outside of the hose with a hose clamp and that worked well...Also, put a switch inside the car to turn on the fan when you want it...it helps if you know that you're going to be doing a lot of idling to turn the fans on before the temp gets high enough to turn them on for you...it gives you a head start and keeps the water a little cooler up front instead of trying to cool down an already overheated engine...
Just some suggestions....

Yes, that way I can set it to the temperature that reaches the engine, i.e. it only comes on if the radiator alone can't handle it anymore. It's an adjustable thermostat.

That would've been nice, but the Hayden controller came with the one you press into the radiator fins.

>on the fan when you want it...
I was thinking about it, got all the parts (still have them), but in the end I was too lazy and couldn't justify the hassle, because all I needed to make sure it wouldn't overheat is tune the thermostat right.

[updated:LAST EDITED ON 14-Feb-02 AT 10:18 PM (EST)]I had one of those adjustable thermostats, but it went dead after about 13 months, so I was forced to wire in a switch!!! And it would have been nice if they would have let you mount that dial inside the cab...that way you could turn on your fan with that switch...
