I'm headed over to Technosquare this Wednesday and since Stillen is on the way there I decided to purchase the pulley, but which one...
Standard pulley:
Pro-Won't affect future S/C kit.
Con-S/C kit might not be available for awhile.
UD pulley:
Pro-More freed up HP.
Con-Not recommended for use with S/C and be replaced.
Both are the same price. Either way is fine with me. I just decided I want to have my fellow members help choose!
