i have one along with the overdrive pulley, the charge stays normal at 800 rpms with the lights, fans, and big stereo on. as for performance i dident notice much because i have a lot of other bolt ons, but maybe if it was my first mod i would have noticed more.

thing is only suppose to give u a couple horses...
i did mine at the same time as headers and catback so i dont know what it really did..
Headers let the car rev quicker too so i cant say if the pulley helped but thinking logically it should help..
Your not going to feel the power gain... but if your looking for every little bit of power then get it.

On the LT1 engine, the airpump is electric and the waterpump is driven off the cam. There isn't a whole lot of accessories driven by the belt and most UD pulley come with alternator overdrive pulleys to keep the charging system up. A unengaged A/C compressor takes less than 1 hp to spin and the PS pump doesn't produce a load until you start to turn the wheel.
I still put one on anyway because I've run out of bolt-ons to put on.
