I installed the ASP alternator pully & the crank pully reciently. The car does not seem to charge the same. When idling in gear with A/C - Bright Lights - & both fans running the volt meter will drop around 11volts or less. Now when you are going down the road it seems to charge past the 13 mark like it use to. I am just wondering if there is something else I can add/do to make it charge like it use to or is this just something I will have to put up with.

P.S. I have a 2002 T/A Vert A4

Any advice is greatly appreciated!!!

You put underdrive pulleys on your car. That is going to slow down the pulley speed, thus giving you some extra power. Unfortunately the draw back is going to be the above described problem. You can put back to stock or you can live with it. Hope this helps.

My '02 seems to be charging-marginal when hot,
from factory. I would see if there is an even-
smaller alternator pulley you can get, to reclaim
more shaft speed there. Otherwise the alternative
is to find an alternator or its regulator module that
can run more field current, or produce more output
with the same field current (I believe this is where
the shortfall lies, the internal self-protection limit
for field current & temperature).
