10.50” TOP INSERT FOR STANDARD RACE CASE SUPERCHARGERS (#2122) The Blower Shop's billet race inserts allow you to tailor blower boost to specifically fit your application. Changing the supercharger inlet opening of the blower allows you to better match boost to the fuel curve or track conditions. The larger opening will result in higher boost at higher engine RPMs. meanwhile the smaller openings will result in increased boost at head of the throttle, but will start to restrict airflow at the top end of the track.
