Vortech Superchargers Tuner Kit - V-3 Si - Polished (1986-1993 Mustang 5.0)
Overview of the Vortech V-3 Si Tuner Kit for Fox Body Mustang
The Vortech V-3 Si Tuner Kit for the 1986-1993 Ford Mustang 5.0 is engineered for builders who want maximum flexibility and higher horsepower potential through custom fueling and professional tuning. This system is intended for modified Fox Body Mustangs and serves as the foundation for high-output, charge-cooled, and competition-level builds.
At the center of this kit is the Vortech V-3 Si centrifugal supercharger, developed through extensive in-house testing and achieving a class-leading 78% peak adiabatic efficiency (SAE J1723). Higher efficiency means lower discharge temperatures, reduced parasitic loss, and more usable horsepower - while also improving durability under sustained boost.
Unlike engine-oil-fed superchargers, the V-3 Si features a fully self-contained lubrication system, eliminating the need for oil pan tapping or external oil lines. This simplifies installation while maintaining proven reliability for aggressive street and race use.
Performance & System Advantages
- V-3 Si centrifugal supercharger with helical-cut gearset
- 78% peak adiabatic efficiency for cooler charge air and higher power output
- Self-contained lubrication system with no oil feed or drain lines
- Excellent foundation for higher boost and charge-cooled configurations
- Designed for custom fuel systems and professional ECU calibration
What Makes This a Tuner Kit
This is a true tuner kit and does not include fuel injectors, fuel pumps, ECU programming, or an air inlet assembly. You or your installer must supply the appropriate fuel system components and custom tuning based on your specific horsepower goals.
For Fox Body Mustang applications, Vortech offers air-to-water charge-cooling systems that minimize pressure loss compared to traditional air-to-air layouts. The compact routing keeps the charge path short, maintaining boost pressure while delivering cooler, denser air for improved detonation resistance and expanded boost capability.
