Okay before I get the Powerdyne sucks, let me tell you I know there are better s/c and I wish I would have gotten the vortech, but too late for that now! Question is does anybody know if I can change the pulley to get more boost and still be safe not to break the internal driven belt. That is the real problem with these systems from what I've heard. Can't up boost, and the belts break often. But I also heard the new ones do not have that problem. Thanks for any help.
