Advanced Roush Supercharger Technology

Eaton TVS R2650 Supercharger System

At the core of this kit is a front-inlet, front-drive, inverted Eaton TVS R2650 supercharger, featuring an optimized high-flow inlet port for maximum airflow and efficiency. The inverted design enables larger, more efficient intercoolers, reducing intake air temperatures and maintaining consistent power under extreme conditions.

• Dual front inlet configuration
• High-efficiency twin intercoolers
• Roush Red painted supercharger head unit
• Optimized for sustained high-RPM performance

Industry-Leading Dual Throttle Body Design

This Roush supercharger kit reuses the factory dual 80mm throttle bodies, preserving a clean, symmetrical OEM appearance while delivering up to 34% more throttle area than typical single-throttle competitors.

Benefits include:

• Improved throttle response
• Enhanced airflow capacity
• Retention of stock induction components
• No compromise in drivability or refinement

Superior Cooling for Consistent Power

Engineered to combat heat soak in high-output applications, the Roush supercharger system includes a robust, track-ready cooling package:

• Large front-mounted heat exchanger
  (installs without removing the front fascia)
• High-flow Bosch PCE intercooler pump
• Custom high-capacity degas bottle to prevent coolant aeration
• Optimized hose routing for improved underhood airflow and appearance

The result is lower intake air temperatures, sustained boost, and repeatable performance lap after lap.

High-Flow Fuel System Engineered for Reliability

To support increased airflow and boost pressure, the kit features a fully upgraded fuel system:

• High-flow dual-cone fuel injectors with optimized director plates
• CNC-machined billet fuel rails for maximum flow with minimal restriction
• Precision injector orientation for consistent fueling

This system ensures reliable fuel delivery across the entire powerband, even under extreme load.

Designed for OEM-Level Fit and Durability

Roush engineers focused heavily on long-term durability and factory-quality integration:

• Custom FEAD system reduces crankshaft load
• Optimized supercharger belt path for improved reliability
• Fits under factory hood and K-brace with no modifications required
• K-brace remains installed during supercharger installation
• Fully plug-and-play wiring

Colder-range Ford Performance spark plugs with reduced gap are included to ensure safe and consistent combustion at higher boost levels.

Quick Installation & Simplified Tuning

Easy Installation

• No front fascia removal required
• Custom-formed hoses for faster installation and clean routing
• Reuse of factory components where possible
• Reduced labor time and installation risk

Roush Diagnostic Tuning Software

Calibration is handled through Roush Diagnostic Tool (RDT) Software, delivering OEM-level flash reliability and diagnostic capability.

• OBD-II connection
• Laptop + SAE J2534 communication device required
• Optimized for drivability, performance, and engine protection

Certified and Warrantied

• SEMA-Certified Emissions Compliant
• 3-Year / 36,000-Mile Limited Powertrain Warranty Included
• Vehicle top speed remains unchanged from factory configuration
• NOTE: Not 50-state legal, EO Pending

Notes:

• Intakes sold separately (Part #422334)
• Not compatible with EU6.2 regulations
