pulleys w/ e-fan

[jomama]

im gettin a set of jet underdrive pulleys along with an flex-a lite-210 e-fan and what i want to know is if i should use the alternater pulley in conjunction with the e-fan because im worried about it draining the battery thanks.

if your only running the e-fan, it should be fine. if you're going to be running a system or a lot of other audio/video stuff, i wouldn't use it.

when i bought it, it was on. from what im told it reduced hesitation a touch and helped gas mileage a little.

You shouldn't notice any difference from having the underdrive pulleys on. If you do notice a drain on it, you might need a deep cycle battery like an Optima Yellow Top to help out.

That was my solution, larger battery.

IMO and my experience with JET pulleys, they suck. The reason being is that Jet sells their set with the alt pulley being bigger than the factory pulley, causing the alt to turn alot slower. March sells their set with the 1 7/8" alt pulley which is smaller than the factory pulley to make up for the huge loss in alt rpm. The 1 7/8" pulley puts the alt rpm almost back to the factory rpm. With the Jet set your alt won't even charge at idle, even without the fans. I learned the hard way, I had to buy the 1 7/8" pulley from March and a new belt. Also called Jet and the place where I bought them and neither would refund my money because I already installed them. Also (I don't know if this goes for the March set too) you will have to grind down the edge and the washer on the factory crank bolts or try to find smaller bolts. If you have bought them already, take them back and get the March set. Also the March set is cheaper by a few bucks. Call March and make sure the set comes with the 1 7/8" pulley, I've heard it does. Just some info so you don't make the mistake I did.

Also with the efans, get a 180* t stat and a bottle of Redline water wetter.

If you do a lot of idling, then no, the alternator pulley wouldn't be wanted. But, if you do enough cruising (doesn't take a lot) to keep the battery at a full state of charge then the large alternator pulley does offer significant savings (as part of the whole package).

Getting used to headlights dimming at idle takes a little while but for those of us old enough to remember driving the old Chryslers, it ain't a big deal. ;)

I don't have pullies and I don't see the need for them. How big of a rwhp increase are you getting from these pullies? How big of a headache are they? I'll pass. I can get a bottle filled for 35 bucks... hehe

The pulleys on my truck gave me almost a .1 of a sec off my 1/4 mile time. IMO, they are worth it. I have the March Performance 4460 Power and Amp series pulleys. Smaller pulleys equal less rotating mass and quicker throttle response and less drag from other accessories.
