As some of you know, I was installing a supercharger on the M3, and it has been officially finished. We finished the install Saturday night, but when I started the car it threw a code, so I had to get a new sensor this morning. The kit is a Vortech V3 centrifugal charger good for 6 lbs of boost with my setup. Should make 625 flywheep hp, or 530 to 540rwhp. When I first started the car up, it hesitated a little bit and then idled very high, but after 5 minutes the motor and charger were running smooth as butter. I drove the car around a few miles with the SES light on just to make sure that everything was good mechanically, and I could already feel the extra power just driving around town. This morning we fixed the sensor that went bad during the install, and all I can say is WOW. I'm still breaking the supercharger in, so no full throttle runs, but at half throttle in second gear from 3 to 6000rpms the tires just spin. The thing I love most about the kit is how stock the car feels other than the added power, still runs perfect around town and is easy to drive. Can't wait to really open her up on the highway.
