Electric fan with alternator

[TNDirtRacer]

Has anyone successfully ran with an electric fan and kept the car cool on DIRT with an aluminum head crate engine?

If so what components did you use? I haerd over and over on other forums that it can not possibly be done. Then I read a post somewhere, where a 4 cyl. is racing without a fan at all and staying cool!

I've tried it on my car.(Not a crate, but a very limited motor.460ish HP)
With an alt, a good fan, the nose cut open, and duct work, it normally ran 220 to 230. I took it off, took the duct work off, and put a good 4-blade fan on it, and it then ran around 180.

When it was running 220, I was always worried about it, and if I got just a little mud in the rad, I was done.

I have seen it done. If the nose, cowl, and air damn create a positive pressure in front of the radiator and the fender wheel opening create a negative pressure then a fan may not be needed until the car slows.
