Pm's will be something with your account settings? I personally dont run a 22 anymore but looking at the size of the speedo you should be ok with a standard shell, you may have to take the fan off the speedo but that shouldnt be a problem...
I run mine with an X12 6.5, its super quick, id suggest a 7.5 as this will be more than fast enough, depends on the track your racing at
