underdrive pulleys with full alternator output?

[rockin_rick]

Which set/brand of underdrive pulleys have the most alternator output? Another way of saying it is, which set underdrives the alternator the least? Is there some custom setup that would work good? (eg. March crank and water pump pulley, with a stock alternator pulley). I assume that I want as small of a alt. pulley as possible, correct? My stereo eats lots of amps.

Thanks,
Rick

Ive heard of people having good luck with keeping the stock alt pulley.. I personaly have the BBK underdrives, and when im at a stop light my headlights dull. I dont have a special stereo or anything.

I believe that all the diff company underdrives are the same size..

ASP makes some pullies that keep the same size alt. pulley. I guess the only reason to change it would be to have a matching set.
