Idk why i said Perrin, I meant to say ATI damper. I don’t really think that it’s so much for power as it is for crank vibrations / keeps bearings happy! I honestly love these ATI dampers.
I’ve asked recently to people running the lightweight ones if they do few different, haven’t heard back yet tho.
I would just think a billet pulley would cause more harm then good because the crank needs some sort of absorption for the vibrations to keep a healthy bottom end.
