    Any turbo'd X2/X4's out there

    I'm a fan of anything that's turbo'd.
    Has anyone tried adding a turbo setup to the new motor without being a full motor build?
    Is there a good reason why I can't find any mention of turbo installs?
    I see they have forged pistons and rods already stock.

    I doubt you would need to do anything to the motor itself due to your last sentence. I don't think anyone who's owned one or is in the market for one has power complaints and the Weller ECU flash\HMF combo seems to satiate those looking for just a little more. Really, anyone looking for turbo power will move up to the newly-updated YXZ as the CVT, which is nearly bulletproof in the X2\X4 isn't suitable for higher HP. Frankly, I'd love to see the YXZ's auto clutch tranny as an option in the X2\X4. I'm certain we would be seeing 70 MPH with it. Still, if Weller came out with a turbo kit for the X2\X4 that would be cool to see.

    I think Massive's right, a turbo would be cool but I think our wet clutches would'nt stand up to long to the added power.

    Yamaha's strength also has a weakness. Their Ultramatic transmission is super solid and performs great, but it has limits and I think that is why they never came out with big engines in their ATV's or UTV's. The YXZ with its 1,000cc and their snowmobiles with high power triples have different transmissions. So it's possible to see something with more power but not with the existing setup.

    What is the "wet clutch"?
    And where is it?

    Of all the popular modern SxS, only the Teryx and Yamaha still use a wet clutch for 100% belt engagement. Polaris and Can Am both use slipper clutches where the belt tension is left loose enough at idle to slip and engage when RPM rises. They are more prone to burning belts as a result but are more efficient.

    Thanks Massive,
    Any idea how the clutch engages and disengages?

    The older generations used only springs to keep the shoes from spreading out under centrifugal pressure. Slug weight kits were used to increase shoe pressure as well as decrease the RPMs at which the shoes engaged.

    The X2/X4 use springs along with rubber durometers to control when the shoes spread out. I noticed with synthetic oil and my additives that shoe engagement occurs quicker. There are no holes in the shoes allowing for aftermarket slugs to be added but as you can see from my linked post, the X2/X4's wet clutch has been beefed up substantially.

    I ride above 7000 feet above sea level most of the time. I have never felt like I was running out of power.
