I am pondering on what engine mods to purchase and was wondering whether the engine fan would be a necessity if I had a supercharger installed. What kind of gains would this prove? Thanks for any help.

 

I have read a lot on the boards here about people switching to the electric fans, usually out of Crown Vics or something of the sort, and that makes a big difference, as I understand it. I don't know if just replacing the blade makes that much of a difference, but check out the electric fan mods on the boards here, that is a world of difference. The Lightning guys can help you out with that one.

 

HI!... YUP! I have the "HPP" twin 16 inch electric fan kit and love it. My truck never overheats and this mod in conjuction with 2 others helped me drop my 1/4 mile time by almost a full second.

 

An electric fan definitely frees up some power; it's a great mod. You didn't say whether you meant electric or an improved traditional fan. Neither is a "necessity". If you're interested in the ATI supercharger, you should look at the intercooler tubing location/shroud modification before you invest in electric fans.

 

I've read where some aftermarket fan blades, such as the flex-a-lite series, flatten out at high RPM's, thus reducing drag and freeing up HP. However, I do not know if this is true. I also have heard that some of those models can fail and damage the engine (one guy I heard from had a ranger with a big motor and one of these fans, the fan broke and put a hole in his radiator. Not cool )

If I was to put an electric in, can anybody tell me how hard it is to do the wiring and electrical stuff. Is it easy?

 

HI!... On a sad note a buddy of mine a few years ago was having a party at his house. One of his buddies was in his garage tuning his "70" cuda. After a while he never came in the house. So his girlfreind went out to see what was up. She found him laying on the floor with his head half decapatated. The aluminum FLEXALITE fan he had on his engine broke off and hit him in the neck killing him instantly. They figure he was leaning over the rad shroud revving up the engine from the throttle linkage and the fan blade broke off. After this, I WILL NEVER RUN A ALUMINUM mechanical fan.!!!!!!!!!!

 

Dang! That's some freaky story. At least he went the cool way..

 

Ok...that really sucks...and I don't plan on getting a piece of shroud through my neck. Just wanted to know whether an electric fan is worth the money for the performance gains achieved on an ATI Procharger. (BANG for the BUCK!) Thank you for everyone's help!

 

Anything that allows the engine to spin more freely will help, it doesn't add power really, just frees it up. Man, that would be a bad way to go, decapitated by a cheap aluminum fan ,,,,98


Don't let this happen to you!!!!!!

 

Sorry I'm late to jump in on this but can anyone help me out here...

I'm looking into getting Pulleys and Electric fans, for a 2001 4.2 F-150.

Can anyone post or E-mail me at Asierra@kpmg.com where to get them from?

While I’m at it I’m also in the market for L Headlights for It.!!!

Thanks,
Andre S.

 

98, where'd your head go?? Least you didn't try to replace the fan belt while it was running. You can't stop that thing with your hands, its like a machine or something!

 

I had replaced the fan on a 460 motor with an aluminum flexi-fan and wound up sending it through the radiator while doing a burn out. I guess it flexed a little too much

Dang it, I still remember it because I trashed a beuatiful continual finned 3 core radiator.
