alternator with od pulley at high rpm
Basically, I'm wondering if I need to switch over to a 145A alternator for future use of e-fans or can just stick with the stock 105A alternator and stick on OD pulley on it.
All alternators are rated to a certain maximum rpm, so my question is can the stock alternator with an OD pulley survive when spinning the engine up to 6k rpm levels??
I am looking to get a BlackBear tune and thought about picking up his e-fan harness and alt OD pulley at the same time, but then this questions popped up. I don't know the max rpm levels of the stock alt, but I don't wanna burn a bearing in there.

Added the e fans several weeks ago, haven't found the 145 alt for the price that I want to pay. Works fine still, but you can watch the volt gauge drop some when the fans come on. The od pulley should work fine, because I have spun the motor up just a little and seen no volt drop. I am still going to do the bigger alt when I find one.

My truck hated my original 192,000 mile 105 amp alternator and electric fans. I could see and hear a change (blower speed) when the electric fans kicked on. I checked it before it died and it was only making like 30 amps under load at idle. I replaced it with an Oreilly reman 140 amp CS144 alternator for 125 bucks. Now there is just a slight dip in voltage as the fans come on but after that it stays right at 13.8-14 volts reading it with a DVOM.
