Thanks Bill. It's much lower RPM increase than I expected. I wasn't sure if most of the kits changed the alternator pulley too, but I see none of them really do.

Some kits out there are still three pulley kits. Just depends on who the mfgr is and what they thought was best! Majority of pulley kits are only 2 pulley kits.
