how much electric fan cfm??

Reason?

1) Horsepower (yes, I know it's only like 5hp)
2) Novelty (It's cool..excuse the pun).
3) This is Texas. Even with a 180 T-stat and radiator and fan intended for A/C (which the car no longer has), and a Mopar high colume water pump, it gets hot when stuck in traffic on our standard 100+ degree days. The motor just doesn't turn enough RPMS to move the air.

My only alternative is a different radiator. If I go that route, I'm going aluminum, but the problem isn't THAT bad (It's already an almost new radiator). It warms up, then drops once I get moving, but DFW is known for stupid accidents that shut down highways...and I don't want my car to overheat.

I actually think I am going to install this 14" on my 4.7L Ram now anyway. Much better suited for the task.

If I go to an electric on the Dart is going to be a 16" moving 2000+ cfm. I know plenty of people that run them here and they seem to do fine.
