Vortech Supercharger System w/ V-3 Si-Trim - Polished w/ Charge Cooler (2007-2008 Mustang GT 4.6 3V) 4FU218-048L
Polished V-3 Si-Trim Complete Supercharger System for 2007-2008 Mustang GT
The Vortech Supercharger System with V-3 Si-Trim (PN 4FU218-048L) is a complete, fully calibrated centrifugal supercharger system engineered for 2007-2008 Ford Mustang GT models equipped with the 4.6L 3V engine. Featuring a high-visibility polished finish, this system delivers Vortech's proven V-3 Si-Trim performance combined with an integrated air-to-water Charge Cooler for consistent power under boost.
On a stock engine with the supplied calibration and 91-octane fuel, this system is capable of producing approximately 462 horsepower and 419 lb-ft of torque at the flywheel, generating up to 10 PSI of boost at factory redline depending on pulley selection.
V-3 Si-Trim Supercharger Technology
The V-3 Si-Trim centrifugal supercharger represents Vortech's most advanced street-focused design, combining a self-contained lubrication system with the high-efficiency "Si" compressor stage. With an industry-leading 78% adiabatic efficiency (SAE J1723), the V-3 Si-Trim generates less heat, requires less drive power, and produces more usable horsepower compared to lower-efficiency designs.
The self-contained oiling system eliminates external oil feed and drain lines, simplifying installation while maintaining excellent durability for street-driven performance vehicles.
Charge-Cooled Complete System Configuration
This is a true complete supercharger system, supplying the required fuel system upgrades and ECU calibration. A supplied Diablosport In-Tune handheld programmer reflashes the factory ECM with a Vortech-developed calibration optimized for 91-octane fuel, ensuring smooth drivability and reliable power delivery.
The integrated air-to-water, dual-pass Charge Cooler significantly reduces intake air temperatures under boost, helping maintain consistent horsepower during repeated acceleration, spirited street driving, or extended high-load operation.
