Vortech Supercharger Tuner Kit V-3 Si Trim Satin w/ Charge Cooler (19861993 Mustang) 4FA218-170L
High-Efficiency V-3 Si Tuner Kit with Air-to-Water Charge Cooling
The Vortech V-3 Si Tuner Kit with Charge Cooler is engineered for 19861993 Ford Mustang (Fox Body) applications that demand maximum flexibility for custom fuel systems and tuning. Built around Vortechs ultra-efficient V-3 Si centrifugal supercharger, this configuration is intended for modified vehicles pursuing higher output combinations beyond entry-level systems.
Continual development in Vortechs test lab produced the V-3 Si, achieving a peak adiabatic efficiency of 78% (SAE J1723). The Si designation reflects its improved, patented oil control system and advanced centrifugal compressor stage. High efficiency reduces heat generation and parasitic drive loss, producing more net power and improving durability.
All V-3 series superchargers feature self-contained internal lubrication, eliminating the need for oil feed or return lines to the engine oil pan. This simplifies installation versus engine-oil-fed V-1 and V-2 units while maintaining Vortechs long-term reliability.
Air-to-Water Charge Cooling for Fox Body Mustangs
For Fox Body Mustang applications, Vortech employs an air-to-water charge cooler to minimize pressure loss. Unlike air-to-air systems that route charge air through long tubing paths and large cores, this design keeps the airflow path nearly identical to the non-cooled setup, resulting in virtually no boost loss. Charge cooling delivers cooler, denser air, raises the detonation threshold, and supports higher boost options.
