Vortech V-3 Si-Trim Supercharger Complete System - High Output Polished (2005-2006 Mustang V6) | 4FU218-628L
High Output Vortech V-3 Si-Trim Supercharger System for 2005-2006 Mustang V6
Vortech offers a fully calibrated high output complete supercharger system for the 2005-2008 4.0L V6 Mustang, designed for both manual and automatic transmission vehicles. This system features the highly efficient V-2 or V-3 Si-Trim centrifugal supercharger combined with a fully integrated air-to-water charge cooling system for maximum power and consistent performance.
This high output configuration increases horsepower from 210 to 330 HP and torque from 240 lb-ft to 337 lb-ft with 10 PSI of boost at factory redline using CA 91-octane fuel.
Advanced Vortech Si-Trim Technology
The 4.0L V6 Mustang system utilizes Vortech's V-2 or V-3 Si-Trim supercharger, developed through extensive lab testing. The Si-Trim features a state-of-the-art centrifugal compressor stage with an industry-leading 78% adiabatic efficiency (SAE J1723), resulting in lower heat generation, reduced parasitic loss, and increased net power output.
Reduced heat improves durability under sustained boost, while Vortech's centrifugal design weighs significantly less than many competing supercharger systems.
Superior Centrifugal Supercharging Performance
Centrifugal superchargers produce greater airflow and pressure than roots-style blowers while operating more efficiently. Vortech supercharger systems deliver exceptional horsepower gains per dollar and, when driven normally, fuel economy may even improve.
