Vortech Superchargers Tuner Kit - V-7 YSi - 10-Rib Serpentine - Satin (Big Block Carbureted Chevy) 4GA218-050
Satin V-7 YSi 10-Rib Tuner Supercharger Kit for Carbureted Big Block Chevy
The Vortech Superchargers V-7 YSi Tuner Kit (PN 4GA218-050) is a high-output, universal-style supercharger package engineered for carbureted Big Block Chevrolet engines. Finished in a durable satin coating, this tuner kit pairs Vortech's flagship V-7 YSi centrifugal supercharger with a robust 10-rib serpentine drive, delivering scalable airflow and dependable belt control for aggressive street/strip and competition builds.
This is a true tuner kit. Fuel delivery and carburetion are intentionally left to the installer, allowing professional builders to tailor the system to engine size, compression, camshaft, and intended use.
Important Tuner Kit Notes
Carbureted tuner kits do NOT include a carburetor enclosure box. A compatible enclosure or hat must be sourced separately. Vortech's PowerHat is available for purchase independently for blow-through carbureted configurations.
Verified & Potential Fitment Applications
This kit 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 system may fit other Big Block Chevy platforms, 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 kit 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-output centrifugal supercharger, designed for extreme airflow and sustained high-RPM operation. This configuration features clockwise (CW) rotation with a straight discharge, making it ideal for large-displacement engines requiring significant headroom for future power increases.
