Ok, so a while ago i got an underdrive pulley set(alternator/crank shaft only) and it said that the alt charge would be low and that was normal. Time went by and the low charge caused my alternator to go bad. So i got a new alternator(ouch) and i put the stock pullies back on. So my question is this, if i change the crankshaft pulley, but keep the alt pulley the same, will it still drain my alt? And if it wont drain the alt, will i see any performance gains?

 

Why even bother doing that. The alternator only draws 2 or 3 horses at top output.

 

I agree, the small performance gain isn't worth the effort and loss in charging. Not to mention the initial expense, and the extra money it ended up costing you.
Sell the underdrive pulleys on ebay, I'm sure some sucker out there will buy into the "awesome h.p. gain" hype.

 

Hahaha alright thanks. I'll probably do that. There just arnt many mods for v6's. Not to mention the 3.4 sucks a big one.

 

I know, I used to have a 94. My wife was able to blow my doors off with her Chrysler minivan.

 

With pulleys though there's more to it than just the pulley. A bad tensioner pulley, bad power steering pump, bad AC compressor can all cause a drain on the engine and alternator.

@Camaro 69, no Caravan can blow the doors off my 95! lol! Not after all that's been done to it.

 

Mine was an automatic too, which compounds the dogginess of the 3.4. Ride in an automatic, then a manual 3.4 Camaro, and you'll realize the night and day difference.
Oh, and hers was a Plymouth Voyager.

 

You know, I've driven Caravans and Voyagers and they actually are pretty quick. It's too bad the automatic 3.4's are slugs and you have to do quite alot to a 3.4L to get it to beat a Caravan!

 

I was at a tire store years ago, getting new rubbers put on my old 94. The guy who road tested the car, also had a stock 94 but with a manual trans. All I had on mine was a CAI and a Z28 exhaust. He commented on how mine was such a dog compared to his, so he took me for a ride. I was blown away by the big difference in acceleration between the two. It wasn't too long after that when I did a V6 to V8 conversion....sold the 94 and bought a 96 Z28.
