newmans ph4s

  1. #1
    does anyone on here run newmans ph4s? I'm considering getting wilder cams and throttlebodies before going to the ring next year.

    Just wondered what sort of power these make to see if it would be worth replacing the piper 285s.

    on a ph4 and bodies youll probably see about 185ish i rekon
    not actually seen anybody using a cam of that kinda profile there usually like a 285 or just crazy

    may need a little headwork and defo some bigger injectors
