Vortech Supercharger Complete System - V-3 JT-Trim - Polished (2018-2023 Mustang GT) 4FQ238-238JT
Polished V-3 JT-Trim Complete Supercharger System for 2018-2023 Mustang GT
The Vortech Superchargers V-3 JT-Trim Complete System (PN 4FQ238-238JT) is a fully engineered, emissions-compliant supercharger solution for 2018-2023 Ford Mustang GT 5.0L applications. Featuring a show-quality polished finish, this complete system combines factory-level drivability with proven Vortech centrifugal performance for enthusiasts who want reliable power without sacrificing street manners.
This is a complete, fully calibrated supercharger system, supplying the necessary fuel system upgrades and ECU calibration required for a true bolt-on installation. On applicable stock engines, the system is capable of producing 692 horsepower and 584 lb-ft of torque with 7.5-8.5 PSI of boost at factory redline using 91-octane fuel.
V-3 JT-Trim Supercharger Technology
The V-3 JT-Trim centrifugal supercharger represents the next step in Vortech's ongoing compressor development. Utilizing a patented oil control system and a highly efficient centrifugal compressor stage, the JT-Trim achieves an industry-leading 76% adiabatic efficiency (SAE J1723). Higher efficiency translates to lower charge air temperatures, reduced parasitic loss, and increased net power output.
Like all Vortech centrifugal designs, boost rises progressively with engine speed, delivering smooth, predictable power that retains excellent street drivability while pulling hard at the top end.
Complete System Advantages
Unlike tuner kits, this complete system includes a supplied handheld programmer that re-flashes the factory ECM with a safe Vortech calibration for 91-octane fuel. Fuel system upgrades are also included, eliminating the need for custom tuning and making this system ideal for owners seeking proven, repeatable results.
Complete systems are available for manual and automatic transmission vehicles on supported model years.
