Weird Supercharger Noise.

[gijosh]

i have had my Mini R53 to about 130 so far. if im really getting on it and i get up to around 100 MPH the super charger makes this really weird noise. has anyone else had this problem? anyone know why?

I've been in triple digits with no real abnormal noise ...
can you give a better description ???

the supercharger goes from whining like normal to more of a screeching noise. unless maybe its not the supercharger. i dont know because the first time i heard it i was doing 130 then the next time i heard it i was doing 100. so i dont know.

Sounds like the belt might be loose/stretched causing slipping at high speed
