Ford focus fans

i dont think that those fans will pull enough air to properly cool your 351. i recommend using a fan from a taurus, V8 mustang, or mark Vlll instead.

If your running cool already, i wouldnt touch it.

I agree, why mess with a good thing-

LOL- when I first read the title Ford Focus Fans I thought it was a thread for fans (people who admire) the Ford Focus..LOL

If you aren't having any cooling issues I wouldn't bother with it unless you are looking for a project. I am not familiar with the focus fan but judging that it is only a 2 liter engine and meant to cool that much I wouldn't have high hopes in having 2 cool your motor. Especially since the modern engines have a much more efficient cooling system too. I would stick with the proven fans such as the mark 8, Taurus, dual spal... and I went a little different the viper fan. I would shoot for a fan in the 3500-4000 cfm area. Another thing to look for is a DC controler. They dynamicaly ramp up the fan speed to compensate for the heat. It really stablizes your motor's temp and doesn't shock your electrical system. I was able to run my viper fan with the dc controler on my stock 5.0 85amp alternator without killing my car at a stop.
