For over 30 years, Vortech has produced some of the highest quality supercharger kits around. For the 2018-2023 S550 GT Mustang, Vortech has you covered with this V3 JT Supercharger Kit (4FQ218-338JT), a surefire way to blow the doors off just about anything in a straight line.

- Big Power Increase: Up To 1,000HP
- Direct Fit Installation
- Ultra-Efficient Design
- Manifold boost pressure: 7.5-8.5 psi @ redline on stock engine

This S550 Mustang system uses Vortech's V-3 JT-Trim supercharger. Continued development in Vortech's Lab resulted in the V-3 Si. The patented oil control system and state-of-the-art centrifugal compressor stage of this V-3 literally blow away the competition. Industry-leading 76% adiabatic efficiency [SAE J1723 standard] means less heat is being generated, drive power is reduced and more net power is produced. Less heat also means better durability. Also, Vortech's supercharger systems weigh less than half of the low-tech competing brands.

For a higher horsepower custom-tuned installation, we recommend this Tuner Kit which does not include a fuel pump, fuel injectors or ECU programmer, This requires you or your installer to provide custom calibration and the required fuel components. The V-3 Si-trim supercharger included with the tuner kit is capable of up to 1,000HP on modified Mustangs. While this kit requires a little more effort, it's ideal if you're after the highest numbers.
