I use a GM CS130. It charges a rock solid 14.1 volts from 1000RPM-7000RPM with a 5" pulley crank pulley.

I Run EFI, 2 wideband controllers, two fans, electric water pump, 2 fuel pumps, lights and wipers. I have run every single bit of that for hours on the highway before. This alternator is one of the best mods I have ever done to my car.
