Stillen Supercharger reliabiity

Lunar-Eclipse

I thought this would be a good place to add my two cents. I just got my car back about a week ago after having the Stillen supercharger rebuilt.

About a month ago I started noticing the supercharger was getting louder. Since I had changed the oil about 1500 miles back I knew that wasn't the issue. But I checked everything anyway. Oil was clean and level was spot on. Belts looked okay. The pulleys didn't seem to have any wobble, etc. I wrote it off to my OCD and my imagination until about a week later where it went from slightly louder to what sounded like metal rubbing against metal. I determined the noise was coming from the supercharger itself and not the pulleys.

I parked it and took it to the shop that had installed the kit a few years prior. They confirmed by suspicions. They suspected one or more of the internal bearings were going bad. I had researched rebuild options before taking it to the local shop and their rebuild estimates where higher so I had them send the supercharger to 928 Motorsports to do the job. I called 928 beforehand and found them very knowledgeable. I did their standard rebuild. Their 1 week turn around time and rebuild cost were spot on. No surprises. I got the car back a little over a week ago and it runs like new. It may be my imagination but the supercharger feels better than new. I swear it's pumping out more power. But I haven't dynoed it to confirm.
