[QUOTE="GT500Steve, post: 14314718, member: 126607"] Thought I would update, and I have a couple additional question..... I went ahead and installed the PA Performance 200amp alternator this past week, as well as the upgraded wiring kit as well. Also, to be safe I went ahead and did a new battery as well. While at cruising speeds the battery voltage on the Aerforce gauge holds at 14.2-14.3 volts, which made me feel more comfortable. However, at idle it will drop down into the mid 13s if I am sitting at a red light with the brakes and AC on, and with the headlights on it will dip into the high 12s. However, tap the gas and it shoots right back up to 14 volts again. When I got the alternator from PA Performance it already had a larger pulley on the alternator to slow the rpms down while at the track (which is probably what killed my stock alt), and I know this can effect charging at idle. Any guys that have done the larger alternator pulley swap have similar issues? [/QUOTE]
