I've got a Ford Lightning with a supercharged motor, and it's not stock, with different pulleys on the blower drive, an intake and exhaust. Stock they make 380, mine more like 450 hp. Still have the stock clutch fan, which is no different than the one on my Ranger. They work well and neither has failed. My Ranger's is 20 years old, as is the water pump it's mounted on. No bearing failure on the pump with 155,000 miles on the clock. My Lightning's is 14 years old with no bearing failures on the 14 year old, 65,000 mile water pump.
I refuse to swap either to Sparky fans. I've had electric fans fail before, and it sucks ass. Never again. Clutch fans rock. I've never noticed any noise from my clutch fans, where some Sparky fans make a hell of a lot of noise when they're on. Some I said, not all. I could give a rat's ass about a few hp from an electric conversion, I'd rather have the already proven stock fans, which have not caused an overheat problem yet, even during 100+ summer days on a supercharged motor with the ac on. Plus I hate all the extra wiring needed to put Sparky fans on. Just plain FUGLY!
There are numerous guys on the Lightning forum I hang out on, that have swapped back to the stock set up from Sparky fans, after they found out that there simply are no Sparky fans that can cool the big supercharged V-8 as well as the stock clutch fan. Some of these guys have built engines and big blowers, and are pushing the nine second bracket, with stock clutch fans.
You like your Sparky fan, you can keep your Sparky fan. I'll stay with clutch fans, thank you very much. That's money I have for something else more important.
