Last night when I remote started my car, I noticed a new noise in the engine bay. It sounds like the bearings on one of the Black pulleys are going south. The sound does not seem to be coming from the supercharger itself, but one of the two Black pulleys.

See picture below



Has anyone else with the supercharger noticed any noise from their pulleys? I tried the wiggle and yank test, and they seem tight, no play, but the belt is so damn tight it's hard to tell. I also did not see any metal dust from decomposing bearings. However, one of them is definitely making some noise.

Has anyone else (who has the supercharger), had any issues with pulley's or noisy bearing?

I also realized last night when going through my car documents, that I do not have a parts list for my supercharger either. Does anyone have one, who can tell me the part number and/or specifications of these two pulleys?

I am thinking it would not hurt to have replacements handy.

Thanks

 

Got a sound clip? You sure it's not just the injectors making a fuss? Mine make enough noise it almost sounds like it's valves knocking around haha

I will try to get sound chip tonight. I think my camera will do that. Anyway, the sound is like a scrapping whine, not a knocking news. My first fear was the supercharger itself, but when I did the screw driver to the ear thing I could not hear anything abnormal from the charger.

Thanks for your help bro.

 

I had to replace one of the pulleys on my old JRSC setup on my old SOHC Si. The pulley made some weird sounds....almost like when you spin a very used skateboard or rollerblade bearing. Anyhow it was like $30.
