So my belt tensioner has been rattling, but I havent had spare time to work on it(newborn and other house projects). The tensioner started making a bunch of noise, and now I am hearing a 2nd sound coming from the supercharger.

Heres the vid, i didnt edit it, car starts around 15 sec in

So does this sound like the charger is slowly dying? its the 2nd whine you can hear aside from the standard SC whine. You can hear it on idle. its not my steering pump, that sound is way different. From what I can tell my belt tensioner is making a squeeling/whistling sound now and shortly after this new sound popped up.

Any help here before I drop a bunch of money on a rebuilt one and tear this car apart?

Thanks!

 

it sounds like your steering pump

 

If it was me...I would replace the tensioner pulley first since you know it's bad...and then see what strange noises (if any) you are left with...and then go from there. Bad bearing like the one in your tensioner pulley can make all kinds of weird noises.

 

the sound moves with the RPMs, I am now thinking its the water pump.

 

I think that your crank pulley is broken or something is wrong with the supercharger belt.Check them out.

 

+1 on the crank pulley. The noise sounds like slight metal on metal. There isn't much room in between the crank damper and timing cover stock so just a little deformation will cause it to rub.
