    Well the smaller the ring size.83mm 82mm 81mm.the more top end you will get, the larger the diameter 87mm like the stock one..the harder the acceleration will be off the line.

    no idea, i just want to try and see, maybe good or bad but something.
    i like the idea of 83mm nozzle with 85mm stearing.

    I have always seen that you should be around 5mm difference in the 2 rings. IE: 82mm in venturi, 87 steering. I run 83/89 now,

    I have a scat steering nozzle with interchangable rings, and a stainless trim ring for sale if anyone is looking for one.

    but not the X boats, they have 87mm nozzle and 88mm stearing, only 1mm. and if you put a 85mm ring in a 06 rxt its only 3mm difference, or if you put 80mm in 06 there is a 8mm difference. thats why i want to try it, its have to be a difference.
    someone try the R&D stearing nozzle?

    I always wondered why the ratio was always mentioned in 2 stroke land but doesn't seem to ever be brought up here in the 4 stroke section.
