Vortech Supercharger Tuner Kit - V-3 Si Trim Black (1986-1993 Mustang 5.0L) - 4FA218-144L
High-Efficiency Vortech V-3 Si Tuner Kit for Fox Body Mustang 5.0
The Vortech V-3 Si Tuner Kit is designed for 1986-1993 Ford Mustang 5.0L Fox Body applications requiring custom fuel systems and tuning. Built around Vortech's ultra-efficient V-3 Si centrifugal supercharger, this tuner kit is intended for modified vehicles targeting higher performance levels beyond entry-level bolt-on systems.
Continual development in Vortech's test lab led to the V-3 Si, which achieves a peak adiabatic efficiency of 78% measured under SAE J1723 standards. The "Si" designation reflects its improved patented oil control system and advanced centrifugal compressor stage. High efficiency means reduced heat generation, lower parasitic drive loss, increased net power output, and improved durability.
All V-3 series superchargers feature internal self-contained lubrication, eliminating the need for oil feed and return lines to the engine oil pan. This simplifies installation compared to engine-oil-fed V-1 and V-2 systems while maintaining Vortech's long-term reliability.
Charge Cooling Advantages for Fox Body Applications
For Fox Body Mustang systems, Vortech utilizes an air-to-water charge cooling strategy to minimize pressure loss. Unlike air-to-air systems that route charge air through long tubing paths and large cores, this configuration keeps the airflow path nearly identical to a non-cooled setup, resulting in virtually no boost loss. Charge cooling delivers cooler, denser air, supports higher boost options, reduces detonation risk, and increases overall power potential.
