Vortech Supercharger System - V-7 YSi - Low Mount - 50mm Cog - Satin (Big Block Carbureted Chevy) 4GA218-060
Low-Mount V-7 YSi 50mm Cog-Drive Supercharger System for Carbureted Big Block Chevy
The :contentReference[oaicite:0]{index=0} V-7 YSi Low-Mount Supercharger System (PN 4GA218-060) is a serious, competition-ready forced-induction solution engineered for carbureted Big Block Chevrolet engines. Featuring a low-mount configuration and a robust 50mm wide cog-drive system, this package is designed for maximum belt control, high-RPM stability, and sustained boost under extreme horsepower demands.
This is a universal-style supercharger system intended for experienced builders who want uncompromised airflow capability and mechanical reliability. With Vortech's flagship V-7 YSi centrifugal supercharger at its core, this system is capable of supporting aggressive street/strip combinations and full competition builds where belt slip and drive losses are unacceptable.
Verified & Potential Fitment
This system has been verified to fit 1964-1972 Chevrolet Chevelle and Malibu models equipped with a cowl induction hood. Depending on intake manifold selection, minor underside hood structure modifications may be required.
While the system may fit additional Big Block Chevy platforms, those applications have not been formally confirmed and should be evaluated during mock-up.
Performance Expectations
Horsepower gains vary based on boost level, engine displacement, volumetric efficiency, and supporting modifications, but typical increases range from 30-75%+. With the supplied pulley ratio, this system produces approximately 5-6 PSI at 5,000 RPM on a mildly modified 454 cubic-inch Big Block Chevy.
V-7 YSi Supercharger Technology
The V-7 YSi is Vortech's highest-capacity centrifugal supercharger, engineered for extreme airflow demands and sustained high-speed operation. This unit features clockwise (CW) rotation and a straight discharge, making it ideal for large-displacement engines and future high-boost or race-only upgrades.
Included Components
- V-7 YSi supercharger with 3.33" pulley (CW rotation, straight discharge)
- Cast aluminum supercharger mounting bracket with all required hardware

Fuel System Requirements
- High-volume fuel pump (installer supplied)
- Properly jetted 4150-style carburetor with mechanical secondaries
- Optional fuel line kits available separately for clean, high-flow plumbing
Cog Drive Advantages
The 50mm wide cog-drive system delivers absolute belt control under high load, eliminating slip commonly seen with high-boost serpentine systems. This makes it the preferred choice for high-RPM racing engines, aggressive boost curves, and applications where consistency and durability are critical.
Installation Notes
- Estimated installation time: 4-10 hours, depending on application
