I put the stock alternator pulley on mine with the underdrive crank pulley. I also have a high amperage alternator which definitely help, but before, I didn't have any problems.

I got my pulleys from http://www.summitracing.com/, but their tech support is little to be desired. I emailed them 3 times and all they could or were willing to tell me was why my system wasn't charging properly, and not how to fix my problem. Again thanks for being here V6. I plan on picking all your brains in the near future as the camaro is paid for. It's my new toy. [img]graemlins/rock.gif[/img]

Sorry to jump in on your post with my own question, but did you guys notice much more performance? I have been debating on doing this mod for a while now, but am still up in the air about it.

What are all of the negative effects that have or can happen, as apposed to the positive benefits?

Thanks.
