Thanks everyone for the info about efan recommendations. I should have included this question - how well does the stock alternator (in my case, on the 4.6L) handle the fans at full power? Is there sufficient juice to turn the fans and run the odds and ends in the vehicle? Don't have any other 'lectric devices other than stock stuff - cd/radio, lights, annoying turn signal blinker sound, etc.

Thoughts are again appreciated.

PS - before I posted, i searched, just in case you wondered

 

I ran my dual 16"ers with the original 95amp? alternator with no problems. I did notice that the a/c fan would run a bit slower at idle, but it was not a big deal.

 

I have the alternator with most amps, forget the # but even without, I'm not seeing a problem running them. Feel confident and do it. Any kit doesn't suck too much juice at all, no worries.

 

should be able to keep the stock alternator

 

stock alternator is more than needed for efans.. just dont get underdriver pulleys and ur stock alternator will be fine.

 

stock works for me too, even with an U/D crank pulley.

I am running the twin flexalite fans, and I only have a problem with voltage when it hits 5600 RPM. Thats when the little alternator that could begins to give up and tells me to F off or let off. But hey, how often are you going to hit 5600RPM?

 

I got the troyer pulleys right now, I plan on getting efans in the near future. Do I need to raise my idle with xcal or what are my choices?
