Surely the guys with Shos have seen the nizpro supercharger system. Puts out about 450hp when added to a 250 sho. There's a v20 on fork running mid 80s with it so that would put a 721 or 920 in the mid to upper 90s I'm thinking, maybe even touch a triple digit light. I can't even drive mine to top potential now so it wouldn't do me any use but is anybody here thinking about it? Imagine a 919 with 450hp. Talk about ypur butt cheeks grabbing the seat lol. Just goes to show what these 4 strokes are capable of
