    The Tommy Jordan mod sounds awesome and cost little to nothing. You'll be glad you did it. Here is an onboard video with it from a ski I recently put together. The exhaust is subtle in the video,...

    No problem. Hopefully some guys get good useable power and less wasted top end rpm as a result of this thread. Once an efficient intake is installed and you're getting sufficient air to the inlet...

    The SHO head has provisions for the intercooler mount. The HO head has the aluminum bosses made into the casting, just not drilled and threaded. This can be done manually.

    The air today was excellent, so I figured I'd do another test. I figured it wouldn't be "as fast" as the GPR 60T nozzle that I made work on this ski, but wanted to try the 14' up FZR/S SVHO 3 degree...

    Just the nozzle...that nozzle is the easiest to switch too if you can swing the rpms enough to still make speed. The speed will be higher per rpm compared to the 87mm. Basically just bolt the...

    Ok, as mentioned the air and weather was far from ideal for testing...but being Louisiana is still basically on lockdown, what else is there to do. As I thought from my previous testing of props and...

    More nozzle comparison pics for those interested. I still haven't gotten to the water to test. It's hot, humid, and overcast this am.

    My buddy sent me a stock 60T nozzle that I modified to work on this ski. By modifying, I installed stainless threaded inserts into the bosses where the reverse bracket mounts. These older nozzles...

    Tommy...it's a Runleader tach and I've had great success with it. I never owned a PET 2100, just the old tiny tachs years ago. The nice thing is the battery is interchangeable and you can get them...

    I just recently purchased a 17' VXR and absolutely love it. I have a GP1800, so I knew what to expect with how the hull rides and handles. I've ridden the earlier model VXR/S, such as you have, and...

    I really don't feel it would pull this prop and nozzle combination to much more being normally aspirated. I know you could run a smaller prop and spin it higher to achieve the same, or better...

    My pleasure. I'm not the guy who is going to have something and settle for mediocre, and half a$$ performance... especially when I know it has more potential. I enjoy sharing from my experiences,...

    70 plus today in good air...same setup. According to Yamaha, the the factory limiter is at 7898. Tach indicated 7900 max. I only made a couple of runs, being it was all it was going to go with the...

    A few pics of the bars. All the harnesses were de pinned and ran through the middle of the stem to hide the wires.

    We have a cool front moving though tonight, and with me having a "non essential" business and them shutting us down with the coronavirus, I figured I'd prepare for shooting for 70 plus on a stock...

    Yes...the FZ SVHO is an 8 vane 3 degree 85mm. The SHO FZR/S nozzle is the 6 vane 5 degree 83mm.

    The smaller the nozzle, the more it limits cavitation from loading the pump more. Not only that, it recovers faster in less than ideal water conditions from the pump being loaded.

    Thank...

    I was blown away by the difference in performance.

    Yeah, those models flew for being NA. Awesome skis.

    Thank you.

    Any FZR FZS prior to the SVHO models. They are cast with 6S5 on...

    As i suspected...I was on the soft limiter. The last 1/4 thottle was useless after the intake. I even tried it with a Soloas concord 13/19. With a full tank of fuel and my daughter we ran nearly...

    I did the ribbon delete (no sleeve installed because I didn't plan on doing it so soon, and didn't have the sleeve), and I modified my seat at the same time I did the intake. I did ride with the...

    And the air is horrible today, so I'm overly pleased.

    Problem solved...I'm about to post results and the solution. Thank you Tommy. Needless to say, I'm thrilled.

    Thank you...I just enjoy "tinkering" and figured I'd make the best of what I had with some time and a few materials. Thank you, and it's my pleasure sharing in efforts individuals may use it as a...
