I couldn't figure out if it's the pulley or the charger that's busted. That tapping sound only happens after the car is warm up.
How do I determine if the pulley is bad?
I could hear it from the cabin.
does anyone knows a good and trustworth place in the bay area to take the car to?
Not the best quality. But here is a link of the jrsc sound. Please let me know what you guys think.

That's definitely not normal sounding, and I would say it's probably not the pulleys either...
arrr..that's what I'm afraid of.
Have you tried to warm up the car and then disconnect the crank-alt belt? Isolate the crank-alt and alt-sc group from the engine itself. That noise almost sounds as if it could be from the engine too...
I took out the sc-alt belt today. The rattling sound went away and there is some free play at the charger pulley. I can move it by hand. I guess my bearing is gone.
spidermancivic, where did you have your charger rebuild? Did you send it back to jackson racing?
Have you guys heard of superchargeronline.com? Should I send it there?
What are my other options?
Thanks for all your help guys.
Have you considered that it might be your alternator that has gone bad? When my bearings went bad in my alternator, it sounded horrible.
Hmmmmmmmm, my problem was worse than just the bearings being bad. Maybe the nose pulley just isnt any good? Make sure that it is internally the blower, because a rebuild is expensive. You can call Jackson Racing and get a qoute and research your options www.jacksonracing.com . They actually send it to a place called Magnusum (I think thats the place that does the actual rebuild). If you are seriously considering a rebuild, you can also opt to buy a used blower on ebay. I have seen them there a few times. You can probably save yourself $200 - 300 buying it used and hopefully not too abused.
You should also pm Jim about your situation since he has alot of experience with the JRSC. He may have ran into a few of his customers who may have had a possible bad blowers. Im not sure if he is fimiliar with the internal repairs of the blower but his experience may guide your decisions a little better.
I have spent alot of money on my JRSC from the rebuild to the belt changes to all the supporting mods. Coughing up $800 for a new rebuild is a pain in the a$$. For what i spent i could of got a very nice turbo setup, but i choose to go the JRSC route because I just wanted to see how far I can go with it. If the blower is bad (definately make sure it is) then just realize that you are at a crossroad where you can choose a different route if you wanted to.
Good Luck!
Thanks,
My mechanic looks at it and believe that it's the charger puller or bearing. Because there are free play on the charger pulley after the belt is removed.
Spidermancivic, what is Jim's display name?
I need to start calling around for rebuild or repair service. and like you said, if it's too much, I might go another route. I'll probably have to do more research on that.
