The 2018-2021 Mustang GT system uses Vortech's V-3 JT-Trim supercharger. Continued development in Vortech's Lab resulted in the V-3 JT-Trim. With its new patented oil control system and state of the art centrifugal compressor stage, this V-3 literally blows 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.
