Pusher Compound Turbo System | 2020-2022 6.7 Powerstroke

The Pusher Compound Turbo System is engineered as a complete, high-efficiency compound setup for the 6.7L Power Stroke platform. The focus is usable, repeatable power across a wide operating range, from daily-driven stock trucks to competitive applications exceeding 1000 HP. Properly configured, compound charging improves low-end response, broadens the powerband, and can deliver measurable fuel efficiency gains under load. The system supports up to ~750 HP using the stock valley (high-pressure) turbocharger and scales beyond that with upgraded components. It is compatible with most BorgWarner S400 turbochargers paired with stock-based or aftermarket valley chargers. IMPORTANT NOTES: Dual alternator and Platinum trim trucks require extension of the passenger-side positive battery cable. This system is not compatible with factory emissions equipment and requires custom tuning to achieve intended performance. Off-road use only. This kit requires a CCV & Coolant reroute for installation, these can be added above if you do not have your own. Optimized Turbo Placement (Industry First) // Includes a sealed AGM battery, CNC press-brake aluminum battery tray, and a TIG-welded low-pressure A/C line to relocate components and position the atmospheric (low-pressure) turbo for optimal plumbing geometry and airflow. Precision Fabrication //
CNC-machined and laser-cut flanges ensure accurate fitment. All assemblies are fully TIG welded with controlled parameters for consistent penetration and minimal internal flow disruption. Serviceability & Install Access //
Component layout is designed for straightforward access during installation and maintenance. Charge Air System //
3.5" intermediate charge pipe with integrated 1/8" NPT port for boost reference. Front-mount routing optimized for flow and packaging. Cold Air Intake //
5" cold air intake with Pusher 50 CAL air filter and pre-filter included for high flow and filtration capacity. Exhaust Routing //
Intermediate exhaust pipe coated in 2000°F-rated Cerakote, hydroformed to match the S400 turbine inlet and routed to maintain clearance and reduce heat soak.
Two-piece downpipe with factory-style spherical outlet flange allows adjustability and a true bolt-on connection to the existing exhaust. Oil System Engineering (Industry First) //
Oil feed for the atmospheric turbo is sourced post-filter to ensure clean, stable supply.
Oversized -12 AN oil drain routes to the upper oil pan above the oil level for proper gravity drain and reduced backpressure risk. Mounting & Durability //
Heavy-duty turbo mount designed to secure S400-frame units under high load and vibration. Connections & Hardware //
Premium oil/water lines and fittings from established manufacturers.
5-ply silicone couplers and full stainless T-bolt clamps at all boosted joints. Compatibility //
Works with Pusher intake and hot-side charge components, and many third-party intake systems. Contact for current compatibility confirmation. Installation //
No welding or major modification required. True bolt-on configuration with detailed, full-color instructions. Typical install time is 4–8 hours depending on experience. Finish Options //
Multiple powder coat colors available.
