Some people would look at you strangely if you said your 2015-2020 Shelby GT350 needed more power. Here at CJ Pony Parts, we would never do that, and neither would Vortech! This V3 Si Supercharger Kit (4FQ218-178L) can reliably boost your Shelby's flat-plane-crank 5.2L V8 up to 775 horsepower.

Features and Benefits:
- Substantial Power Gains
- Direct FIt Upgrade
- Ultra-Efficient Design
- Manifold Boost Pressure: 6.0-6.5 psi @ redline on stock engine

This system utilizes Vortech’s V-3 Si-Trim supercharger. Continued development in Vortech's Lab resulted in the V-3 Si. The "i" stands for improved and with its new patented oil control system and state-of-the-art centrifugal compressor stage this V-3 Si-Trim literally blows away the competition. Industry-leading 78% 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.
