I have the BBK underdrive pulleys with stock water pump and stock alternator. The only thing I noticed that is a little annoying is that when I'm at idle the lights will dim a little and then come back up to normal when I start moving. I plan to replace the alternator at some point so that doesn't happen anymore.
