I've been down this road with my Cuda, so I'll make a few hopefully helpful comments: make sure your charging system and wiring is up to snuff. I highly doubt that the typical 79A Mopar alternator will cut it. The stock 12 ga charging wire will definitely not be sufficient, so start thinking about a higher output alternator and a much bigger charging wire. You also need to decide on your fan control system. Are you going to simply use a switch to turn the fan(s) on/off? Probably not the best idea for any sort of city driving, so think about what fan controller you want. There are many different options available.
Just wanted to mention these things, because they are often overlooked, but they are equally as important as choosing the fan(s) themselves. I can go into more detail about what I have done if you want.
Hope this helps.
All good advice. We are both well aware that the current factory square-back is not going to get the job done if my dad decides to go with twin electric fans. The charge wire has been upgraded already to either 10 or 8; I forget now. I was planning on using two relays to control the fans. The fan closest to the radiator inlet would turn on when the ignition key was set to the 'run' position. So it would always be running when the engine is running. I was going to use this relay setup (
Hayden Auto Relay) to control the other fan and have it come on at around 185 or 190 degrees. I am aware of electronic fan controllers (
ex: Dakota Digital electronic fan controller); but was trying to stay away from something like that.
I am curious, what shrouding and fan setup did you go with? Did you try hard to get a factory setup (factory shroud, factory fan, factory viscous clutch) to work before going electric? I am very much in favor of staying with the mechanical if possible; but I have my doubts that is going to work in this scenario.
