GM Big Block TBI Gen 6 3.8L Whipple Marine Supercharger System

GM BIG BLOCK TBI GEN 6 3.8L
WHIPPLE MARINE SUPERCHARGER SYSTEM

The Whipple Gen 6 3.8L Marine Supercharger System for compatible GM big block fuel-injected/TBI applications is designed for high-performance marine engine combinations that need instant boost response, strong torque, and configurable EFI support.

This system is built around a cast A356-T6 aluminum intake manifold, low-profile intercooler configuration, and Gen 6 3.8L Whipple twin-screw supercharger. The twin-screw design delivers immediate boost response with throttle input, helping support stronger low-speed torque, faster planing, improved acceleration, and increased top-end power when the complete engine package is properly matched.

The TBI/EFI system configuration supports a complete marine engine-management package with standard GM-style sensor integration, ignition support, fuel-system options, and custom MEFI4B ECM calibration support. Available options allow the system to be configured around the engine build, accessory-drive layout, injector needs, intercooler selection, fuel-system requirements, deck height, pulley color, and finish.

Whipple marine supercharger systems are designed for customers building or upgrading serious GM big block marine combinations. Final performance depends on the selected configuration, engine condition, displacement, compression ratio, camshaft, fuel quality, cooling capacity, calibration, boat setup, prop selection, and installation quality.
