I will mention that the sound of the gears clacking in the supercharger housing at idle is pretty loud... to the point where I thought there was an issue with the unit. It prompted me to send in the charger unit to vortec (the makers of the v3 charger in most of these s/c kits i.e. ess vf etc ) for inspection and they said everything was fine. FYI this inspection / service that includes replacing of the bearings/seals runs about $400
I'd also like to point out that software is very important like others have mentioned. I ran the VF tune for about 800 miles before I decided it was just too rough for the street. The idle was too high and the timing was very advanced. I was willing to sacrifice slightly in performance but gain reliability going with a retune. If anyone wants information on who I had tune the car feel free to PM me.

Not one issue with my car. Nothing. Runs perfect all the time. It's my daily driver but it still gets out to stretch its legs occasionally.

Installed SC when M3 had 6K miles, now has 30K. No problems ever including over 40+ track days.
Replace Engine Oil and SC Oil every 3K miles. Blackstone Report trending on both, no issues.
4 years later and now I am replacing the rubber hoses/belt as preventive maint.
SC and don't look back!

Awesome info guys! Proves supercharging is pretty much the best thing you can do for these cars!
