I dunno, maybe this is old to you fellas, but i just found this out. Unorthodox has a Light-weight UDP that keeps the same diamater for the alternator and AC. but underdrives the powerstearing. I think thats great! here's what they had to say:

The third type [Ultra Sc pully] is the stock diameter or overdrive crank pulley, utilizing the original belt layout (Ultra Sc). The section that drives the alternator or aftermarket supercharger in this version is either the same diameter or slightly larger than the OEM crank pulley. The other belt section/s not used for the alternator or supercharger are up to 20% smaller. This prevents accessories like the a/c from robbing precious HP from your engine. This version is designed to maintain alternator output at exactly or slightly above stock output levels for car owners with big stereos (over 600 watts) or for audio competitions where system voltage must maintain specified levels (see your sanctioning body's rules). This version is also designed to either maintain the original level of boost from the aftermarket supercharger kit or increase the boost (see the application guide for available sizes).

any opinions or first hand experiences?!

check out the datasheet and install instructions, etc. for the UDP specific to our max:

hmm, I have never seen UR pulleys like that, though I do like the idea. I haven't put on a UDP yet as I have a few subs in the back, and my alt is a bit weak, I might look into one of those.
