Thank Morris,

I use the 8102 alternator now, that 3" pulley looks good and has a deeper groove than what I have now. I will give it a try I already pulled the revs back from 8200 because that was a sure belt loss every time. Turning it slower with the 3" pulley will certainly reduce belt stress and the larger deep groove pulley will track better too. Napa belt will be cheaper than what I run now, not so sure that top cog is a good idea either seems to twist easier and then go upside down.
