Supercharger snout pulley needs to be replaced
For a little bit now i have heard this noise coming form the engine and we know its the pulley that is connected to the snout. I am wondering if there is a place where they sell the pulley by itself to replace it. Also any other ideas will be welcome too.

Intense, ZZP, and probably a few others that have smaller Hi-po versions including a modular setup. Otherwise, GM sells them...
I don't think I have any of mine anymore.

Re: Supercharger snout pulley needs to be replaced
ZZP sells the stock 3.8" pulley for $10.
However, I guarantee that nothing is wrong with the actual pulley. It's either the snout bearings or the rotor bearings. Cheapest to just replace the SC.

Re: Supercharger snout pulley needs to be replaced
My first question was going to be "did you check the S/C oil to see if there was any in there" figuring a bearing failure would be due to oil loss or high load on the snout, but figured I'd just answer the question.

Re: Supercharger snout pulley needs to be replaced
Few months ago I filled up the oil for the SC but the noise keeps going. So im not sure what it is. When i put some WD 40 on the side of the pulley it stops the noise for few minutes but then it goes back again.
