    Hello, I've a high pitched noise who comes only above 2900rpm, ( higher pitched than the normal whine) and only when full throttle or almost ( 95% ). It comes suddenly, 1 second after the car started accelerating...
    Thanks if somebody knows what It could be...

    Here is a vid, you hear it coming suddenly ...

    Welcome to MA! I could not hear the noise you are talking about. I do have a few questions. How many miles are on your R53? Have you done any mods to the car? When was the last time you changed the belt, belt tensioner, idler pulley? Have you had a good look at the crank pulley? If the rubber is cracked it could be going bad. Lastly have you ever changed the oil in your supercharger and is there any noice like a rattle coming from it at idle?

    I didn’t hear the high pitch sound either but then again my hearing is not what it use to be. MCS02 gave some good advice on where to start looking for known R53 problems and Welcome to Motoring Alliance.
