Vortech V-15 Z-Trim Supercharger Head Unit for C5 / C6 / C7 Corvette

The Vortech V-15 Z-Trim centrifugal supercharger head unit was designed for C5, C6 and C7 Corvette applications with substantial airflow and horsepower demands. It combines an all-billet gearcase, a 5-axis-machined billet impeller and a high-diffusion housing developed in Vortech’s SAE-J1723-compliant test cell.

Application and installation

Designed for C5, C6 and C7 Corvette applications. This listing is for a supercharger head unit, not a complete bolt-on installation kit or a claim of direct replacement for every Corvette trim. Confirm bracketry, pulley alignment, oil feed and drain, intake clearance, discharge routing and supporting-system compatibility for your specific engine and existing supercharger setup before ordering.

The Z-Trim name honors Zora Arkus-Duntov, known as the Father of the Corvette.
