Pulley questions I'm going to have to take out my alternator soon (separate thread about that), and I'm considering getting a new belt while I'm at it. However, I'm considering getting ASP underdrive pulleys in the future. I have a few questions about the pulleys now that I'm considering replacing the belt:
1) If I were to get the underdrive pulleys, would I have to change belt size?
2) I always see an option for a "15% alternator" pulley in addition to the underdrive pulley. Does this increase the speed at which the alternator turns to counterbalance the decrease from the underdrive pulley?
3) What kind of HP gains can I expect out of the underdrive pulleys with and without the alternator pulley?
TIA.

you will need smaller belts, if you have a system or something that drins power then you will need the overdrive pulley for the alt. they dont come with the belt unless you order it and typically 5-12 hp gains
