Vortech Superchargers Tuner Kit - V-2 Si-Trim (No Charge Cooler) - Polished (1999 & 2001 Mustang GT 4.6L 4V) 4FR218-178SQ
Polished V-2 Si-Trim Tuner Supercharger Kit for 4.6L 4V Mustang GT
The Vortech Superchargers V-2 Si-Trim Tuner Kit (PN 4FR218-178SQ) is a polished-finish centrifugal supercharger system engineered for 1999 and 2001 Ford Mustang GT models equipped with the 4.6L 4-valve engine. This tuner kit is designed for experienced builders who want maximum flexibility, allowing custom fuel system selection and ECU calibration to meet specific performance goals.
Capable of supporting up to approximately 725 horsepower depending on engine modifications and tuning, this configuration is supplied without a charge cooler and does not include fuel management upgrades or programming. Complete systems for this application have been discontinued, making this tuner kit the primary option for high-performance custom builds.
V-2 Si-Trim Supercharger Technology
At the core of the system is Vortech's V-2 Si-Trim centrifugal supercharger, featuring a high-efficiency impeller and compressor housing developed in Vortech's supercharger test cell. The SQ (Super Quiet) gear-drive system delivers smooth, quiet operation with excellent durability under sustained boost conditions.
The engine-oil-lubricated V-2 series is well suited for applications that see extended boost, such as road racing or high-load street use, and supports the addition of external oil cooling or filtration if desired.
Performance Capability
- Horsepower Potential: Up to ~725 HP (application, fuel system, and tuning dependent)
- Boost Level: Application dependent based on pulley selection
- Efficiency: High-efficiency centrifugal design for reduced heat and consistent power delivery
Tuner Kit Configuration
This Tuner Kit includes the primary supercharger hardware but intentionally omits fuel system upgrades and ECU calibration. This allows racers and custom tuners to tailor injector sizing, fuel delivery, and engine management to their specific build requirements.
Important: This system is supplied without a charge cooler. Any references to charge-cooled configurations apply to discontinued variants and are not part of this kit.
