Jonas, Your turbo is undoubtedly not shot. That supercharger noise your hearing is more than likely air escaping between your turbo and the exhaust manifold. The bolts that hold the turbo to the manifold have a common problem with coming loose. When this happens it will make the noise you are speaking of. Check it out. Should this be your problem it will be a simple fix.
yeah ... it still holds boost, and the sound only occurs at high rpms... i can be at 10psi at around 4k and u wont really hear the sound then... i will check these bolts... its not smoking, it still holds boost... errrr
