Vortech Supercharger System - V-2 Si Trim - Complete Kit Polished (2005-2006 Mustang GT 4.6L 3V) - 4FU218-018SQ
462HP Vortech V-2 Si Polished Complete Supercharger System for S197 Mustang GT
The Vortech V-2 Si Polished Complete Supercharger System for the 2005-2006 Ford Mustang GT 4.6L 3-Valve is a fully calibrated, bolt-on forced-induction solution designed to deliver reliable, repeatable power with OEM-level drivability. This system supports both manual and automatic transmission vehicles and increases output to 462 horsepower and 419 lb-ft of torque at factory redline using 10 PSI of boost in High Output configuration.
Developed through extensive testing in Vortech's engineering lab, the V-2 Si-Trim centrifugal supercharger features an advanced compressor stage capable of achieving 78% adiabatic efficiency (SAE J1723). Higher efficiency means less heat generation, reduced parasitic loss, and more usable power - while also improving long-term durability under sustained boost.
Integrated Air-to-Water Charge Cooling
High Output systems include an integrated air-to-water, dual-pass charge cooler engineered for consistent intake air temperatures during aggressive street driving or track use. This cooling system improves detonation resistance, stabilizes power output, and requires minimal maintenance.
