RE: UnderDrive pulleys
Not sure, I have it, figured for 170 bucks why not. John did a write up here:

RE: UnderDrive pulleys
I've asked this question before myself. Most every thread I've read shows that if you do BOTH pulleys you'll kill your battery...

RE: UnderDrive pulleys

Anyone interested in it I may be wiling to let it go. I havent installed it yet because it would be worthless since I am getting a SC in the next month or so

RE: UnderDrive pulleys
I actually did it myself! 
I ordered GT takeoffs from Diversified Marketing and did the install myself. On a nice afternoon, it was a fun little project...took about 2 hours or so (including some beer breaks!).

Ilduce321, thanks. I'll just do the alternator change.

Who did the GT grille work (pony, foglights) on your V6???
