Talking Re: Supercharger Noise - Take a listen

You got a S/C for 1000$. How is that possible, where did it come from?

I have a concern that the used s/c may have had a noise making it available? Do you know the pedigree of the old (new) s/c ?

If you change things and they dont change, then you have not changed the problem. I apologize for the circumlocutory logic here.

Again you have this noise at idle, is it there if you drive from a stop at idle and below 5 mph? S/C will be off if you creep up to 5, any gas and its on.

When you start out and go up to 10 or 15 MPH so that the noise of the road does not drown it out, is it the same noise now that the S/C is engaged.

With the belt off is the noise gone?

You have listened to the bearings with a mechanics stethoscope and hear the sounds loudest near the input shaft?

Thanks for the efforts.

Woody
