Vortech Supercharging System w/ V-2 Si-Trim - Polished (2001 Mustang Bullitt 4.6L 2V) 4FL218-078SQ
Polished V-2 Si-Trim Supercharger System for 2001 Mustang Bullitt
The Vortech Supercharging System with V-2 Si-Trim (PN 4FL218-078SQ) is a complete, CARB-approved centrifugal supercharger system engineered specifically for the 2001 Ford Mustang Bullitt equipped with the 4.6L 2-valve engine. Featuring a show-quality polished finish, this system delivers significant, repeatable power gains while maintaining the refinement and street-friendly nature expected from a factory-quality upgrade.
On a stock Bullitt, this system safely increases output from 265 horsepower to 390 horsepower and torque from 305 lb-ft to 396 lb-ft. Vortech's centrifugal boost curve provides smooth, linear power delivery that builds with RPM - perfectly suited for spirited street driving.
V-2 Si-Trim Supercharger Technology
The V-2 Si-Trim centrifugal supercharger is an engine oil-fed design that utilizes Vortech's proven SQ (Super Quiet) gear-driven technology for quiet operation and exceptional long-term reliability. Developed using Vortech's advanced supercharger test cell, the high-efficiency impeller and housing design delivers strong airflow with reduced heat generation.
Dedicated oil feed and drain assemblies provide consistent lubrication and cooling even under sustained boost conditions, making the V-2 Si-Trim a trusted solution for dependable street performance.
Fuel Management & System Integration
This complete system includes a fuel management upgrade designed for stock engine configurations. Vortech supplies calibration and components intended for factory engines running stock exhaust systems or most aftermarket cat-back exhausts.
Important: Vortech does not provide tuning for vehicles equipped with aftermarket throttle bodies, cold air intakes, headers, off-road mid-pipes, or other engine modifications. Modified vehicles will require custom tuning, and not all ECU box codes are supported.
High Output System Option
Vortech also offers a high-output supercharger system configuration featuring a fully integrated air-to-water charge cooler. With increased boost and improved air density, high-output systems raise performance from 265 horsepower to 415 horsepower and torque from 305 lb-ft to 402 lb-ft.
Charge-cooled systems require a battery relocation kit (PN 8N150-010, sold separately).
