What wrong with the stock fan and fan clutch? I really don't recommend running electric fans unless you live in cool climates. Electric fans just do not pull air through the radiator like a stock set up with a fan shroud. Most people who do electric fans usually make a thread about how there is car overheating later down the road. True story.


I did the electric fan set up myself in the winter time. Everything was cool until the weather started warming up. By late spring early summer it started getting hot and my car temps started going up. Eventually, my car started overheating. I flushed the system, did the Water Wetter thing, cleaned the debris between the radiator and condensor, new thermostat, and radiator cap. Nothing helped. I eventuall went back to the stock fan and clutch set up, and my temps went back down to normal. Alot of people go through this.

Who knows maybe you'll have luck with them. Whatever you do don't sell your stock set up if it's still working good. Keep them cause you may need to put it back on.

The blackmagic fan is pretty killer, Ive used it on many cars of mine in the past. Currently on my supra I plan on running a ford taurus fan as I here that is the ultimate for a cheap price and ease of finding!

what are those CFM rated at?

if it is with zero pressure drop. those CFM rating are as useful as bad case of hemeriods with no preperation H. That radiator will cause a significant amount of pressure drop across the fan (read a hell of lot lower number than the 2800 cfm that you are quoting).

OEM fans. They pull a lot more current but hey, they pull alot more air.

I've only ran it to pull. I'm not sure if there's a benefit to running both push and pull. Maybe someone with more experience will chime in.

Unless it was a closed system with the fans being the only in/out a push pull setup won't make a noticible difference. Air column fans would work well in that
setup but as far as I know they don't make them large enough for those setups.
