Vortech Superchargers Complete System - V-7 YSi - Low Mount - 10-Rib Serpentine - Satin (Big Block Carbureted Chevy) 4GA218-040
Low-Mount V-7 YSi Complete Supercharger System for Carbureted Big Block Chevy
The Vortech Superchargers V-7 YSi Low-Mount Complete System (PN 4GA218-040) is a high-horsepower, carbureted Big Block Chevy supercharger solution engineered for serious street/strip and competition builds. Finished in a durable satin coating, this system utilizes Vortech's flagship V-7 YSi centrifugal supercharger paired with a 10-rib serpentine drive and rigid low-mount bracketry for maximum belt control and reliability.
This is a universal-style complete system intended for vehicles equipped with carbureted Big Block Chevrolet engines. Fuel system components must be supplied by the installer, allowing the system to be tailored to the engine combination and performance goals.
Verified & Potential Fitment Applications
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 bottom-side hood support modifications may be required.
While the kit may fit other Big Block Chevy-powered vehicles, those applications have not been confirmed and should be evaluated on a case-by-case basis.
Performance Expectations
Depending on boost level, engine displacement, and volumetric efficiency, this system is capable of delivering approximately 30-75%+ horsepower gains. With the supplied pulley ratio, the system produces approximately 5-6 psi at 5,000 RPM on a mildly modified 454 cubic-inch Big Block Chevy.

The V-7 YSi is Vortech's highest-output centrifugal supercharger, designed for extreme airflow and sustained high-RPM operation. This unit features:
- Clockwise (CW) rotation
- Straight discharge configuration
- High-efficiency impeller optimized for large-displacement engines
This makes the V-7 YSi ideal for aggressive Big Block Chevy applications where power scalability and durability are critical.
