    Thats the size of the opening on the ring. So you can change your exit nozzle size from 80 mm to 83 mm.

    The smaller ring will choke the nozzle...lowering rpm...slowing hole shot...but....increasing top speed. Conversly...the larger rings will raise rpm...increase hole shot but top speed will suffer.
