Vortech V-7 Heavy Duty JT-B Supercharger Head Unit - CCW Rotation - Straight Discharge - Satin 2A159-090
Satin V-7 H/D JT-B Centrifugal Supercharger with CCW Rotation
The Vortech V-7 Heavy Duty JT-B Supercharger Head Unit (PN 2A159-090) is engineered for high-output, heavily modified engines that demand extreme airflow and sustained boost capability. Representing the next step in compressor development, the V-7 platform features a 5-axis CNC-machined billet impeller and a high-diffusion housing developed and validated in Vortech's SAE J1723-compliant supercharger test cell for outstanding efficiency and power potential.
This configuration utilizes counter-clockwise (CCW) rotation with a straight discharge and a durable satin finish, making it ideal for custom and race-oriented layouts requiring CCW drive compatibility.
Advanced V-7 Series Supercharger Technology
The V-7 Series combines Vortech's latest aerodynamic advancements with proven race durability and is designed to fit most existing Vortech mounting bracketry. Built for applications with highly modified engines and extreme CFM and boost demands, all V-7 units feature Vortech's exclusive D-port volute to improve discharge efficiency and maintain airflow stability at elevated pressure ratios.
Given its airflow capacity, the V-7 requires the use of a Vortech Racing Bypass Valve or larger to properly manage compressor discharge flow.
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 ideal for race applications and sustained high-RPM operation. The H/D design is also compatible with cog pulley / Gilmer-style drive systems, ensuring reliable power transfer in extreme boost environments.
