GM Big Block Fuel Injected Gen 6 3.8L Whipple Marine Supercharger System

GM BIG BLOCK FUEL INJECTED GEN 6 3.8L
WHIPPLE MARINE SUPERCHARGER SYSTEM

The Whipple Gen 6 3.8L Marine Supercharger System for compatible GM big block fuel-injected applications is designed for custom and upgraded marine engine combinations that need serious big block power with instant twin-screw boost response.

This port-injected system is built around a low-profile A356-T6 aluminum intake manifold and a Gen 6 3.8L Whipple twin-screw supercharger package. The combination is designed to support strong low-speed torque, faster planing, improved cruise performance, stronger acceleration, and increased top-end power when the engine, fuel system, cooling system, calibration, and installation are properly matched to the build.

The system includes a port-injected intake layout with a cast aluminum throttle body, 8 injector ports, high-flow fuel rail, progressive linkage, adjustable TPS, and dual IAC capability. The 10-rib belt-drive configuration is selected around the engine and accessory-drive combination, while available intercooler, fuel injector, pulley, finish, deck-height, and horsepower-range options allow the system to be configured for the intended marine build.

Whipple marine supercharger systems are engineered for customers who want broad torque, immediate throttle response, and high-performance marine capability from a complete supercharger package. Final performance depends on the complete engine combination, selected options, fuel quality, calibration, cooling system capacity, installation quality, boat setup, and operating environment.
