Vortech Supercharging System w/ V-2 Si-Trim & Charge Cooler - Satin (1999 Mustang GT 4.6L 2V) 4FL218-030SQ
Satin V-2 Si-Trim Supercharger System with Charge Cooler for 1999 Mustang GT
The Vortech Supercharging System with V-2 Si-Trim and integrated charge cooler (PN 4FL218-030SQ) is a complete, CARB-approved high-output centrifugal supercharger system engineered specifically for the 1999 Ford Mustang GT equipped with the 4.6L 2-valve engine. Finished in a durable satin coating, this configuration pairs Vortech's proven, engine oil-fed V-2 Si-Trim with an air-to-water, dual-pass charge cooling system to deliver maximum power with consistent thermal control.
This charge-cooled setup represents Vortech's high-output system. With increased boost and efficient inlet air temperature management, power increases from 260 horsepower to 402 horsepower and torque from 302 lb-ft to 400 lb-ft on a stock engine, while retaining excellent street manners.
V-2 Si-Trim Supercharger Technology
The V-2 Si-Trim centrifugal supercharger is an engine oil-fed unit utilizing Vortech's SQ (Super Quiet) gear-driven technology for nearly silent operation and exceptional durability. Developed in Vortech's supercharger test cell, the high-efficiency impeller and housing design delivers strong airflow with reduced heat generation.
Integrated oil feed and oil drain assemblies provide reliable lubrication and cooling under sustained boost, making the V-2 Si-Trim a trusted choice for long-term, high-performance street use.
Integrated Air-to-Water Charge Cooling
This system incorporates a fully integrated air-to-water, dual-pass charge cooler designed to significantly reduce intake air temperatures under boost. The closed-loop, maintenance-free design allows for additional horsepower gains and improved consistency during extended high-load operation.
Note: Charge-cooled systems require a battery relocation kit (PN 8N150-010, sold separately).
Fuel Management & System Integration
This complete supercharging system includes a fuel management upgrade intended for stock engine configurations. Vortech supplies components and calibration designed 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.
