I have a ESS Twin screw kit the TS2+ for sale. I'm asking for 4000 shipped. I bought it from a member on the board but I haven't drove the car at all once I did the install. Mainly because I couldn't pass the inspection test. the headers and the programming prevents the car from passing. If you use it without the cams and headers and the TS2 software and not the TS2+ then your would pass inspection.

The supercharger is in great condition. Pull like a freight train with massive amount of torque. It is the most linear supercharger I've ever driven. Around 2K you feels tremendous power. Im getting married in 2 months and I'm parting out my toys. I also have supercharger cams for 700, but I havent had a chance to remove them yet.
