    Venturi Nozzle and Pump Cone

    As I read in this amazing thread http://www.greenhulk.net/forums/showthread.php?t=191532
    Nozzle and Cone are things that is worth it to think about.
    I like to have a red Pump Cone - the color is a important detail for me - tuning on second place.
    Nevertheless there are no reason not to make both in the right way.

    I have a RXT-Xas 2014 S3 hull and I read here: http://www.4-tecperformance.com/inde...oducts_id=2246
    - the 2012 S3 has an oversized nozzle 87mm. So I go to my Jet an try to do measure.
    Can you have a look at my picture - Is this the nozzle that we talking about, where I do measure 83mm?

    So, my question: It is wrong to buy the:
    "R&D Billet Adjustable Anti-Cavitation Cone Kit for RXP-X 260 using 83-84mm Nozzle"?
    It will not fit my RXT-X ? Any other suggestions?

    Thanks for answer. To make things from any metal in any color I have a good friend he is a professional in such things (electroplating and anodize).

    I asked the same questions about my rxpx 2013 the cone will fit but the I control skis you can't run adjustable nozzle you would need to bore your stock one. Guys are say 6 to 9 mm of spacers on the cone and 87 on the nozzle from what I have read here.

    Hello Jafo, sorry, I dont understand - maybe because it is my bad knowledge of the english language.
    Which cone will fit? The "Lucky 13" suggested from mibunkerking ?
    And I dont want run a adjustable nozzle. I dont want to change my nozzle.
    My stock nozzel is 83mm. And I am think this is a perfekt size. Is it not?
    You mean it is better to go with a bigger size of nozzle (87mm) and longer cone ?
    If it so - it is no option for me. To much effort / cost for only to have a red cone on the nozzle
    Anyway thanks for answer.

    No problems if you put the cone in with no spacers you will gain top speed. If you put in around 5 or 6 mm of spacer this will improve hole shot.

    Credit for this info thanks to Mibunkerking

    The more spacers=lower rpms=better hole shot=lower topspeed
    Less spacers=higher rpms=worse holeshot=higher topspeed
