Electric fan CFM flow????
OK heres the deal,i found a nice dual electric fan set up,it flows at 4,600 CFM but draws a max of 28 Amps.Is this type of amperage gona drain my battery at all or kill my alternator or should i run the fan with some sort of capacitor to keep it from drawing so many amps??? If its gona be too much of a problem i might go with the single fan that flows at 2,950 CFM and only draws 9.5 Amps.

What dual fan setup did you find that is 4600 cfm? I might be interested in the same kind of setup. I have been researching elec fans for a couple weeks & found that Lincoln Mark VIII's came with a factory single fan that produces over 4000 cfm. If Ford can do it with their electrical system, I'm sure we can.
Let me know the name brand and model number if you would. All the dual fan setups in Summit seem to be rated at 2500 cfm - 2850 cfm or "up to 250 hp."

I'm not up on fan amperage ratings, but I would expect the max of 28 amps would be drawn only at startup. It takes a lot of current to accelerate the fan from stationary to whatever bazillion rpms it runs at. This only lasts for a few seconds. The majority of the time, the fan is being maintained at constant speed, taking less current. Thus, in my opinion, it wouldn't be a problem. Of course, if they are rating it at 28 amps continuously to keep the fan spinning (doubtful in my mind), what I've said doesn't matter.
