    Bored Nozzle question.

    I have a bored nozzle that it 87.5 cm across. Could anyone elighten me as to size and what that will do in terms of acceleration? verses 87 or 86 cm's. Thanks.

    Are you measuring your steering nozzle or your pump nozzle?

    Damn, that's big! I thought you were measuring the wrong nozzle, because my steering nozzles on both MSX and SLX were about 87mm, but it was too cold to pull my steering nozzles to see what my stock nozzles were....

    So I guess that means a thumbs up then hey! Sweet! I'm looking for bottom end, not top speed. Like they take off at a race. 30 guys all pulling wheelies and 150 ft jet blast out the back!

    Well, I spent about a half hour on the phone with Dave at Impros a few weeks ago, setting up my Jetmate. He's making me a custom prop for the SXR/Jetmate build.

    What I came away from the call with was this: boring the nozzle will definitely improve bottom end, and then a higher pitch impeller should bring back the top speed lost from boring it. From what he said, peak speed can be modified by adjusting these variables to get to the power peak.

    I didn't ask him what he thought about the Wetwolf AAT, wish I did. I've been happy with the results of one on my MSX.

    First off, there is no way you are measuring 87.5 cm across. You most likely are measuring 87.5 mm. (<---note mm vs cm) Dang metric system! 1cm=10mm. I believe the stock pump nozzle is 84mm, guys usually bore them out to a max of 87mm. Then there is me, I accidentally bored out to 87.3mm. Hopefully it doesn't bulge from the water pressure. If it does, I have another stock nozzle coming for backup (high speed tests).

    Nope!, your wrong, it's cm's! I converted a 5 gallon bucket for a nozzle! I want this thing to fly!. I think that was the first time I ever used a metric anything (ruler) but a craftsman wrench! . Just remember, I have your parts sitting here! lol , Keep messing with me!. he was saying something about a pisser manifold wasn't he? hmmm, I don't remember,!

    Maybe I can borrow a digital caliper and see exactly if it's 87.5mm or not. Looked like it from using that canandian ruler! .lol

    This nozzle is very thin!. I'll show ya later on tonight when I get the camera. So the turning nozzle doesn't have to be bored? or can it be? would it help? help what? turning?

    Turning nozzle is supposed to be 3mm larger than the pump nozzle. If it isn't, you will find the steering very "heavy".
