    Jerry would it be possible to select any other sizes? The RIVa comes with the 81-82-83mm. It would be nice to try an 80 mm 84 mm 85 mm

    No sorry, I have all the rings made up already and the 4 sizes are 80mm, 81mm, 82mm and 83mm.

    Also, IMO any size smaller than 80 or bigger than 83 is where pump efficiency is going to start decreasing, all other things equal.

    The OD on these rings is slightly larger than a Riva or Skat ring so those will not fit. At least not without securing them in place. So basically the largest diameter you can have after machining the nozzle to fit these rings will be the diameter of the nozzle itself (without a ring installed) post-machining. That brings it to around 88mm.

    your machinist will measure the Fizzle ring and then machine your nozzle to fit the rings

    i used used to love the pull of the early px's - weren't they 87mm?

    Could i run an 87mm on 2013 rxp260 , I realise I'd sacrifice some top end ... But I'm in chop a lot so I prefer hook up and acceleration ?

    With this you can have the best of both worlds. You bore the 83mm stock nozzle out to match the adjustable rings -- that being approximately 88mm. That way you can run 5 sizes: 80mm ring, 81mm ring, 82mm ring, 83mm ring, or 88mm (no ring)...It really helps for adjusting peak RPMs when the weather changes without having to touch the prop. If you change your mind about max acceleration you can put in the 81mm that has long been known for being the ideal size for top speed on a stock pump and pitch your prop accordingly.
