Overdrive my HO alternator?
Overdrive my HO alternator? I logged battery voltage and above 4800RPM
voltage drops to just around 12.5v.
Idle and below 4800RPM are fine. (13.5v)
This is with a 200 AMP alternator,
2AWG battery cables, an Optima red top that are less than a year old,
and an UD pulley.
My stereo system is upgraded but nothing special,
and I power a laptop with V2 Flashscan for data logging.
Should I change the alternator pulley?
The stock alternator pulley is around 11% bigger than the Load Boss.

Actually it replaced a broken stocker. 
IIRC there was a dip in voltage with it and the stock alternator.
I'm wondering why there is a drop at high RPM.
