I plan on getting a 5250rpm (or close to) chip for my 6AL. If I get to a 3:1 ratio with a new pulley, it would mean the alt. would be spinning at 15,750rpm when I'm bouncing off my 6AL rev limiter. I generally grandma my stuff. If it ever does get wound out, it would be for seconds at a time. I think I'm gonna go for it
Voltage regulator is working good. Needle stops moving up at 14v.
EDIT: I guess the assumption I'm making is that nominal ratio is 3:1. If I get to 3:1 then my bearing life is nominal as well if that is typical from the factory. As-is at 2.36:1, my alternator will last till I'm eleventy-two.
