    Explanation of stinger mod on 150?

    So my buddy just got an 03 ultra 150 and we have been messing around getting it to have a snappier power band from the start. He just ordered some 46 mm domes. I was reading on here and people are talking about a "stinger" mod. From what I've been reading it basically dries out the pipe from the start? Does this work pretty good/ hows it done if so. Thanks in advance!

    IMO - that stoooopid Stinger Mod ain't worth a shit.

    Those Jet-Works Valves fail all the time and if not adjusted properly can create an overheat condition, and/or melt exhaust hoses inside your hull.

    There are other mods that are much more beneficial to incorporate.

    Good Luck !!!

    Hello blairwill4, I am not sure what problems "Spooling", had with the Jet Work Valve ... or he just heard of someone who had a problem. I for one, do have the Jet Works Hole Shot kit installed .... and it works by holding off the water until it reaches a pre-set RPM. Mine is set for 3500 rpms. It is a very simple little valve that you can adjust to your liking. It is easy to test often if you suspect any reason it may not be functioning as it should. I have had mine now for an entire race season & starting my 2nd season. Not one issue or concern. The expert who can answer all your questions on how it works, reliability, etc. Is Rich, @ WFO Performance . You can contact him here on the Hulk. I for one, love the boost I get out of the hole. Good Luck

    I've got the stinger mod on my Ultra. Have not had any trouble with it, but I don't think the improvement is that great.

    Don't waste your money on the stinger mod. I tried it, 3 jetworks valves and 2 burnt exhaust later, I ditched it.
    Some people have issue with the exhaust hose coming off, clamps to weak, (T clamps are best)
    You must run a strainer if your considering it to keep crap out of the valve.
    I just did not want to be "wondering if the exhaust is cooling" after the valve kept failing.

    Did not notice that much of a difference over stock to be honest.
    spend the money on the triple pisser mod, won't get you any power but you know your cylinders are cooling.
    Spend your money elsewhere.

    I had that mod when it came with my stxr.. eh ended up pulling it off and putting it back to stop and selling the modified stinger. I wouldn't bother, 3 blips of the throttle before getting on that throttle does the same thing.

    Remember, the mod is for an improved hole shot ... from a dead still. You can not blip your throttle while in starting gate waiting for a release. If you don't need the extra boost of a boat length or two & are not considering CC racing ... then you might not need the Jet Works Valve. Good Luck

    basically we wave jump. So im going rather slow into the waves. Im wanting that hole shot. We ride polaris slx 1200s a lot and up top they are not as fast but their powerband on the low side is much snappier. Trying to achieve that basically.

    I wave jump also, 3 blips of the throttle work for me.

    Unless Your racing like Ozark which made a very good point, its not worth it atleast in my book, shred master would be a better investment

    What does a shredmaster do though besides add stability? its not cheap for a shredmaster and i dont think weve ever been like man we wish this ski was more stable. Compared to the slxs is as sturdy as can be.
