This is my supercharged BMW 330Ci. I am considering selling this kit. This video was taken literally minutes before the entire system came out of the car.
I had to remove it because of the state of California :(. The Supercharger was in perfect working order. The light hissing you hear as the throttle opens up is the check valve between the idle control valve and the right 90 degree elbow seen from this perspective. There is nothing wrong with the system.
Although I never put my car on a Dyno, Active Autowerke claims the car makes in the 300 hp to 320 hp range with this kit which is approximately a 50% increase in this engine's power. The butt Dyno seems to agree.
The kit has a Rotrex Supercharger (no clutch) and a modest sized JDM Intercooler. Peak Boost is approximately 8 psi.

2001 BMW 330i VF-E Stage 1 SC Kit - First startup
Video taken of first engine startup after the SC was installed. Bumper, engine covers and driver's side headlight aren't on yet, but the video is to show that car starts up fine with CELs and idle hiccups.
