Vortech Supercharger System - V-2 Si Trim - Complete Kit Satin w/ Charge Cooler (2005-2006 Mustang GT 4.6L 3V) - 4FU218-020SQ
462HP Vortech V-2 Si Satin Complete Supercharger System for S197 Mustang GT
The Vortech V-2 Si Trim Complete Supercharger System in satin finish is a fully calibrated, bolt-on power solution for the 2005-2006 Ford Mustang GT 4.6L 3-Valve. Designed for both manual and automatic transmissions, this High Output system delivers a massive jump in performance, boosting factory output to 462 horsepower and 419 lb-ft of torque at factory redline using 10 PSI of boost.
At the heart of the system is Vortech's ultra-efficient V-2 Si centrifugal supercharger, engineered with a state-of-the-art compressor stage capable of achieving 78% adiabatic efficiency (SAE J1723). Higher efficiency means reduced heat, lower parasitic loss, and more usable power - while maintaining excellent durability for long-term street or track use.
Air-to-Water Charge Cooling for Consistent Power
This system features an integrated air-to-water, dual-pass charge cooler designed to stabilize intake air temperatures under sustained boost. Cooler, denser air improves detonation resistance, supports higher boost levels, and delivers repeatable power whether on the street or at the track.

Frequently Asked Questions
Is this system CARB legal?
Yes. 2005 Mustang GT models built after April 30, 2005 and all 2006 Mustang GT models are CARB legal under Executive Order D-213-27. Earlier 2005 vehicles are off-road use only.
What makes the V-2 Si ideal for sustained boost?
The V-2 Si uses an engine-oil-fed lubrication system, providing superior cooling and durability during continuous boost conditions such as road racing or extended high-load driving.
