I have a powermaster "high output" alternator and at idle with accesories my guage is reading below 13 volts, close to redline. Not only does it read that but my headlights get dim and turn signals barely blink, it's bad. I found this through searching TGO : http://store.summitracing.com/partde...5&autoview=sku

Apparently the stock pulley has a diamter of 1.9xx and this is 1.6xx. My volts never exceed 13 and supposedly people said with this they're at about 14 constant. Anyone ever do this?
