    ET 135 + 3mm for 300 flutter

    I know this has been discussed slightly but has there been any failures with the flutter/vibration from this wheel?
    i tried it with aluminium hard pipes to front and had slight flutter vibration if not under throttle.
    Changed to a rear intake set up and that thing was emphasised by it and now has a slight vibration at certain rpm but smooth under acceleration.
    surly it canít b just harmonics if a rear set up makes it worse?
    makes me wonder if the bearings are suffering from it.
    limited class only allows this wheel as an upgrade so not much other choice for upgrade.

    Do u all just take the wheel out? It’s like the Solas impella dump bin spending more money on shit parts with no recalls.

    I don’t have any video sorry and won’t be going out for a few weeks. It’s the vibration from the flutter that’s concerning. They also said the 13/18 vibration was normal too though.

    The flutter is compressor surge and it's normal for the high boost superchargers. It's not hurting anything.

    Would adding a bov help with this surge then?

    I don't recommend a BOV on the Sea Doo's. It's not needed due to the design of the clutch on the supercharger.

    thanks mate. Itís the increase in vibration from a front set up to a rear thats the concern as I was thinking it would be less.
    Appreciate the feedback.
