Vortech Supercharging System w/ V-3 Si-Trim - Satin (1999 Mustang GT 4.6L 2V) 4FL218-010L
V-3 Si-Trim Satin Supercharger System for 1999 Mustang GT 4.6L 2V
The Vortech Supercharging System with V-3 Si-Trim (PN 4FL218-010L) is engineered specifically for the 1999 Ford Mustang GT equipped with the 4.6L 2-valve engine. Finished in a durable satin coating, this complete system delivers a proven, reliable power increase while maintaining factory-like drivability and refinement.
On a stock Mustang GT, this system safely increases output from 260 horsepower to 364 horsepower and torque from 302 lb-ft to 371 lb-ft. Vortech's centrifugal supercharger technology provides strong, linear power delivery that builds with RPM - ideal for street-driven performance cars.
V-3 Si-Trim Supercharger Technology
The V-3 Si-Trim centrifugal supercharger features Vortech's advanced impeller and housing design developed in their in-house supercharger test cell. Equipped with self-contained internal lubrication, the V-3 eliminates the need for engine oil feed and drain lines while delivering excellent efficiency, durability, and reduced maintenance.
Vortech's SQ (Super Quiet) gear-driven design ensures near-silent operation with unmatched long-term reliability, making it well-suited for daily-driven performance Mustangs.
Fuel Management & System Integration
This complete supercharger system includes a fuel management upgrade designed for stock engine configurations. The supplied calibration and components are engineered to work with factory engines running stock exhaust or most aftermarket cat-back systems.
Important: Vortech tuning support is limited to stock engines with minimal bolt-on modifications. Vehicles equipped with aftermarket throttle bodies, cold air intakes, headers, off-road mid-pipes, or other engine modifications will require custom tuning. Additionally, not all ECU box codes are supported.
High Output System Option
Vortech also offers a high-output supercharger system configuration featuring an integrated air-to-water, dual-pass charge cooler. High-output systems increase horsepower from 260 to 402 and torque from 302 lb-ft to 400 lb-ft.
Charge-cooled systems require a battery relocation kit (PN 8N150-010, sold separately).
