Overdrive alternator pulley
I am taking my crazy project truck up to Burning Man in a few weeks. It will be enduring high heat, low constant idle, and a heavy load. You can think of the truck as having to endure a slow hot parade.
Some of the suggestions I heard were to put a smaller pulley on the alternator, so that it will produce enough current at idle speed. My questions are as follows: should I bother with a higher output (read expensive) alternator, or stick with mine as is? Can I drive with the smaller pulley on the interstate for 12 hours (how long it takes to get to Burning Man from my house)? Or will it blow up the alternator by spinning it too fast? It's possible, but a pain to change the pulley at Burning Man, but I really don't want to have to do car maintenance up there.
Any advice?

Unless you have a hot rod engine that turns very high rpm turning the alt. and water pump faster wont hurt anything. Finding the pulleys is another matter. Power master offers an altenator pulley that is 2 1/4" in diamter I think. Another alternative might be a crank pulley with larger diameter pulleys on it.
iF you find any let us know. I would like to turn my water pump faster.
