so there has to be a downside 2 this, correct? Or everyone would be driving around with Hi-Po alternators. . . .

Right now, with my new OEM alternator, my voltage reads 14V in the morning, and driving around with the AC on and radio, dips down to about 13.0-13.2V. It will, however, dip to 12.6V on occassion when I coast to neutral at stop signs, etc. SO would a high performance alternator prevent the dip in voltage??

PS, but is there a shelf life to alternators?? Because I just replaced mine and couldn't justify buying a new one, but seeing as that it's a GB price, I could swing it if I know I can shelf it until I kill the stock one. . . .
