Vortech V-7 Heavy Duty JT-B Supercharger Head Unit - CW Rotation - Straight Discharge - Polished 2A158-098
Polished V-7 H/D JT-B Centrifugal Supercharger for Extreme Power Builds
The Vortech V-7 Heavy Duty JT-B Supercharger Head Unit (PN 2A158-098) is engineered for high-output, heavily modified applications with extreme airflow and boost requirements. Developed as the next step in compressor evolution, the V-7 platform incorporates a 5-axis CNC-machined billet impeller and a high-diffusion housing refined in Vortech's SAE J1723-compliant supercharger test cell to deliver exceptional efficiency and top-end power capability.
This configuration features clockwise (CW) rotation, a straight discharge, and a polished finish, making it ideal for race-oriented builds that demand both maximum performance and show-quality presentation.
Advanced V-7 Series Supercharger Technology
The V-7 Series combines Vortech's latest aerodynamic advances with proven race durability. Designed to fit most existing Vortech mounting bracketry, the V-7 supports vehicles with highly modified engines and extreme CFM and boost demands. All V-7 units utilize Vortech's exclusive D-port volute to improve discharge efficiency and airflow stability at elevated boost levels.
To meet these airflow demands, the V-7 requires a Vortech Racing Bypass Valve or larger for proper compressor discharge control.
Heavy Duty (H/D) Race Configuration
This Heavy Duty (H/D) JT-B configuration is equipped with high-speed ceramic hybrid ball bearings, making it well-suited for race applications and sustained high-RPM operation. The H/D design is also compatible with cog pulley / Gilmer-style drive systems, providing reliable power transmission in extreme boost environments.
