Vortech V-7 Heavy Duty JT-B Supercharger Head Unit - CW Rotation - Curved Discharge - Satin 2A158-100
Satin V-7 H/D JT-B Centrifugal Supercharger with Curved Discharge
The Vortech V-7 Heavy Duty JT-B Supercharger Head Unit (PN 2A158-100) is engineered for high-output, heavily modified engines that demand extreme airflow and boost capability. Developed as the next advancement in compressor technology, the V-7 platform features a 5-axis CNC-machined billet impeller paired with a high-diffusion housing, both refined in Vortech's SAE J1723-compliant supercharger test cell to maximize efficiency and power potential.
This version uses clockwise (CW) rotation with a curved discharge and a durable satin finish, offering additional routing flexibility for custom and race-focused engine bay layouts.
Advanced V-7 Series Supercharger Technology
The V-7 Series blends Vortech's latest aerodynamic developments with proven race durability and is designed to fit most existing Vortech mounting bracketry. Intended for applications with highly modified engines and extreme CFM and boost demands, every V-7 unit incorporates Vortech's exclusive D-port volute to improve discharge efficiency and maintain stable airflow at elevated pressure ratios.
Due to its airflow capacity, the V-7 requires the use of a Vortech Racing Bypass Valve or larger to properly manage compressor discharge flow.
