So right now i'm at the point where shaft & blower are off the car. I took a video spinning each one by the pulley to record the noises. Hopefully you guys can tell me if it means bearings/seals need replacement. I'm waiting to get my hands on an impact wrench to take these further apart. But if things sound good at this point, i wont have to.

At this point i'm considering getting it rebuilt by Vortech (~$350), 928 Motorsports (~$450), or doing it myself (~$???). Do u guys have opinions?

1) Spinning by supercharger pulley, camera makes focusing noises few seconds in.

2) Same as above except recording impeller side

3) Spinning shaft with pulley

The only video i found as reference is this one, my s/c doesn't make as loud grinding noises as his does in the video:

 

sounds ok. If you got the money and just want to play it safe sure go for it, it's already out
