We stay away from HP estimates because there are too many variables. You need to let us know what you got Rick because this forum is based on real world applications and facts from people like you and me. Seriously, let us know if you notice better spool up, less taper up top, loudness, etc. Tell us your impressions. That's what people really want to know. :thumb:
P.S.
Take some pics too because HKS makes some really nice stuff.
