That is all uncammed of course.

Oh it's great and all but I really want someone to try and fit the v7 (apparently they will put the v4 housing on the v2 case now) with it's bigger 60k+ rpm limit and 2"larger impeller. <- if that fits it will be cool. the V7 should bolt to the v3 bracket the volute is just a little bigger or if they somehow fit a T-trim impeller on the v3
