As mentioned, I had great success with a brand new factory impeller and the GPR 60t 5 degree 85mm nozzle with the thin diffuser vanes that I drilled and tapped for the reverse provisions. I really like that setup. Keith
    I must be doing something wrong.

    1. I bought the outer steering nozzle, and I'm going to assume that was the wrong thing to buy. The part number is 6S5-R1313-01-00. When I saw 6S5, I assumed that I got the right thing. So there is an inner nozzle that I need to get? Can you please assist with a part number or the actual name of this part so I can get it right?

    2. Recently my 2014 VXR went from a bone stock top speed of 64mph down to 59mph seemingly overnight. I have followed this thread and have installed a brand new air filter directly on the throttle body, did the ribbon delete, removed oil to below the high-level mark, and have a straight through exhaust now instead of that funky setup from the factory.

    I can tell that I have better power now, and it sounds great. However, I only gained 2mph and now only topping out at 61mph at around 7500rpm. I was hitting 65mph a few months ago with no mods.

    I know the engine is capable of hitting the rev limiter, because when I hit a big wave and I'm on the throttle it will peg the rev limiter hard. I assume that I don't have the 7200rpm limit problem if the motor is doing this right? I have checked the impeller by looking inside the rear nozzle, and there are no visible dings or scratches. It looks great.

    ksalles I'd REALLY like your input, as I'm at a loss here.

    What cone air filters are you guys buying? And do you need an adapter with it to attach it straight to the throttle body?

    I purchased a RS13050 filter clamps down nicely on TB just installed the other day along with a ribbon delete , intake sounds good

    Thank you. I ordered one before waiting for this post. And sure enough I measured the damn entire diameter of the original hose and not the actual inside diameter . I will be ordering this part now. For now..it fit on the air box side... Click image for larger version.

    What are you guys doing with the fuel line ? Has it always been attached to the air intake ?
