Know that it results in more HP due to less engine strain. Am concerned about A/C, H2O pump, and Alt in summer stop & go traffic.
What do you Gurus say? Yes/No and Why
What is the Cost vs Benefit? I.e. UD Pulley makes 3 HP but runs down battery etc.

I had it on my C5, My engine temps were right at 180, A/C worked in vegas in july, and my volt meter still showed 13.5-14 volts charging at idle. Plus it will net you 8-10 RWHP. Now for the down side, DON'T just do a pulley the labor alone is will run you $800-$1000. It's the same labor for most of a cam change. $ for HP it's not cost effective. It's a no brainer when you do a cam change. Then there's no extra labor involved. Just parts. It will run you about $280 including belts and new bolt.
