    Is this also sign of SC slippage?

    I have 2006 Speedster 200 430hp. on one of the engine I can clearly hear SC winning at throttle and engine sound is more stable, on the other one I do not get this (i think) normal sc noise, just engine, it gathers rmps slower then other, and it sounds to me different.
    so is this sign of SC slipping, boost leak or what?

    not sure about rmps at WOT, but the thing that one engine falls behind in rmps gathering is definite, the one that doesnt have distinct SC noise gets to wot later...

    Some sc whining is normal as the bearings wear. Sevier whining can be a sign of water or salt getting into the intake causing wear on the bearings. Also the sc dosen't make boost until 6000+ rpms. If one is slipping and one is not the engines may appear out of sync at wot...
