For all you guys using a 25% underdive pulley
Did you change the alternator pulley as well!!!!
My voltage kinda sits under 13 but rises as I accelerate
So I'm wondering if this could be my issue !!!!

Thanks!!!!

No issues.
I have sat in traffic for hours with it reading below 12V.
AC on, headlights on, wipers on.
It does make you wonder...

You might want to get your alternator checked out.
Mine died from old age about a year and a half after my HB.
Not related, but I noticed in traffic I was making 11.3V, I figured I needed to correct that.

FYI,
May want to check into the brand Billet Alternators. They are reported as to having a very high output at slower speeds that stock units.
Here a link for the Corvette.

There's a demo video also on you tube. I think mechman would be the search name for it.

I think that wayback has one installed in is vette.
