While this underdrive pully reduces drag from the A/C, power steering and alternator what impact does it have on the effectiveness of those accessories, particularly the A/C?

Alternator - seemingly no difference. After weeks with the 608 in place and being daily driven - no issues with starting (or low voltage-caused issues).
A/C - might be too early to tell - haven't yet reached the heat of the summer. So far, so good, though.
Water pump - might be too early to tell - haven't reached the heat of the summer. So far, so good, though.
If you're used to "listening for everything" from your engine you will probably notice a difference in tone or frequency because the driven items are running slower and presumably generating their "noise" differently. I definitely noticed it on the first few drives.

Can anyone advise when this will be available for the 997.1S with the 3.8L? It says pre-order on the website, how long until the pulley is available for the 3.8L?
