underdrive pulleys

What issues has anyone experience with the factory size but lighter pulley.I have a smaller than stock plus lighter pulley and the pulley is great but I'm switching to a lighten stock diameter,because when the car is at idle my voltage always drop to almost 11.5 volts or 12 with the lights and heat off.I purchase this pulley from a company called TEAGE AUTO in ashville nc years ago.

I'm running a factory size aluminum pulley. No issues to report.

Voltage at 600rpm is still going to be low though. It's just not enough to allow the alternator to easily generate adequate power.

I've had no problems with the factory size lightweight pulley that motorsports warehouse sells. Have them on 2 svx's.
