2002-2017 Mercury Marine 383 Stroker 400 HP Whipple Supercharger System

2002-2017 MERCURY MARINE 383 STROKER 400 HP
WHIPPLE SUPERCHARGER SYSTEM

The Whipple Supercharger System for compatible 2002-2017 Mercury Marine 383 Stroker 400 HP reman small block engines is designed for customers who want big block-style power and torque without the added weight and fuel economy penalties of a larger engine package.

Whipple's twin-screw supercharger technology delivers instant boost response and broad torque across the RPM range. Unlike power adders that need RPM before they become effective, the Whipple twin-screw design can generate boost quickly with throttle input, helping the 383 Stroker deliver stronger low-speed torque, faster planing, improved acceleration, and increased top-end power when the full setup supports it.

This system is listed to add up to 200 HP to the already powerful 400 HP Mercury Marine 383 Stroker platform in supported applications. The result is a small block package designed to outperform many stock big block combinations while keeping the compact size and weight advantages of the Mercury reman small block engine.

Each system is set up with a conservative 5-6 psi boost configuration and is designed for 91 octane minimum fuel. Whipple also provides ECM/PCM calibration support to properly manage fuel, spark, and engine protection strategies for the supercharged application. The system is designed to work with factory wiring in supported applications.
