V-2 Si Centrifugal Supercharger Tuner Kit for Fox Body Mustang 5.0
The Vortech Superchargers V-2 Si Tuner Kit (Part Number 4FA218-140SQ) is a race-focused centrifugal supercharger package designed for the 1986-1993 Ford Mustang 5.0L. Finished in satin, this tuner kit is intended for modified engines requiring custom fuel system components and custom tuning, making it ideal for serious street/strip and competition builds.

NOT AVAILABLE OR LEGAL FOR SALE IN CALIFORNIA. This system is intended for off-road and racing use only.
V-2 Si Supercharger Technology
The V-2 Si supercharger features Vortech's proven centrifugal compressor design with a helical-cut gear set optimized for high-RPM stability and sustained boost operation. The "Si" designation represents improved efficiency and airflow capability developed through Vortech's extensive testing program.
The engine-oil-lubricated V-2 platform is preferred for applications involving sustained boost conditions, such as road racing or extended high-load operation. A dedicated oil cooler and/or oil filtration system can be added for extreme duty cycles.
