Whipple Stage 1 to Stage 2 Hardware Upgrade Kit (20152022 Hellcat / Demon / Trackhawk)
Overview
The Whipple Stage 1 to Stage 2 Hardware Upgrade Kit is the factory-correct path to unlocking additional airflow and fuel capacity from your existing Whipple Stage 1 supercharger system. Designed specifically for Hellcat, Demon, and Trackhawk platforms, this kit adds the critical Stage 2 hardware required to support higher power levels while maintaining OEM-level fit and reliability.
At the heart of the upgrade is Whipples billet 112mm high-flow throttle body, paired with -8 billet fuel rails and upgraded fuel plumbing. This combination removes the airflow and fuel restrictions found in Stage 1 configurations, allowing your Whipple supercharger to operate more efficiently at elevated boost and horsepower levels.
Performance Highlights
- Converts Whipple Stage 1 systems to full Stage 2 hardware spec
- Billet 112mm throttle body dramatically increases inlet airflow
- -8 billet fuel rails support higher fuel demand
- Designed for higher boost and increased horsepower potential
What This Upgrade Does
Stage 2 Whipple systems rely on increased airflow and fuel volume to safely support higher output. This hardware kit delivers both by replacing the factory or Stage 1 throttle body with a 112mm billet unit and upgrading the fuel system with -8 feed capacity. The included crossover hose, banjo fittings, and fuel pressure sensor ensure proper fuel delivery and monitoring under demanding conditions.
This kit is ideal for owners planning pulley changes, higher-octane tuning, or additional supporting mods that require the airflow and fuel capacity only Stage 2 hardware can provide.
