What type of sound is it? If its a loud screeching sound it could be the belt slipping. After my mechanic did my install he had me drive it hard for a few mins to make sure everything was O.K. My understanding is that the belt is self-adjusting so if thats your problem it should correct itself shortly.

: Hi guys, just had installed this afternoon. It took the mechanic about 1.5 hour to get it done. But, I'd say it's worth the wait:)...I noticed the engine rev smoother from 3000 rpm and up. The original pulley that being replaced is big, and I mean gigantic compare to the Ert unit. I haven't seen any negative side effects so far, but of course it's only been a couple of hours, but one thing that I did notice is I heard this sound that I never heard before at above 4500 rpm(Chris, if you read this, have you heard any kind of sounds in your M roadster?)
: IMHO, I'd say it's worth the money I spent on this thing, but I wouldn't know about the pre-96 M3 though(since they charge more for those cars)

: Best regards,

: Pete
