It was originally tuned for 14lbs (1 bar) and for a year now i bumped the boost up to 1.2bar (17-18psi). Last summer the car ran 11.9@118 with nothing changed from the previous 3 years of the initial build. I have not taken the car to the track this year.

The motor is now showing signs of weakness but a year ago drove just like the car shown in the video above. I have another stock b20 that will be put in sometime along with a larger turbo. I feel that B20s go well with boost if you tune properly.
