6.7 Powerstroke Engine Background and Evolution
Collaboration with AVL and Ford “Scorpion” Design
When Ford introduced the 6.7 L Power Stroke in 2011, it was the first diesel wholly engineered in-house, codenamed “Scorpion” for its unique reverse-flow head layout where the turbocharger sits in the block’s valley . The compacted graphite iron (CGI) block, offers strength and reduced weight compared to traditional gray cast iron. Bosch’s CP4.2 high-pressure common-rail system, employed in Ford’s 6.7L Power Stroke diesel engines from 2011 to 2019, supports up to five injection events per cycle, optimizing combustion efficiency and enabling B20 biodiesel compatibility. Starting with the 2020 model year, Ford transitioned to the Bosch DCR (Dual-Channel Radial) fuel pump, addressing reliability concerns associated with the CP4.2 system.
Generational Output Increases
- 2011–2014 (EPA Tier 2): 400 hp / 800 lb-ft after software update
- 2015–2016 (EPA Tier 2): 440 hp / 860 lb-ft with revised turbo and injectors
- 2017–2019 (EPA Tier 3): 440 hp / 925 lb-ft, maintaining power but boosting torque
- 2020–Present (EPA Tier 3): 475 hp / 1,050 lb-ft with upgraded aftertreatment
Why People Delete and Upgrade 6.7 Powerstroke?
Reducing Back-Pressure and Thermal Stress
Factory-installed diesel particulate filters (DPFs) and diesel oxidation catalysts (DOCs) effectively reduce particulate matter and certain pollutants but can increase exhaust backpressure, potentially impacting engine performance. Aftermarket mandrel-bent delete pipes free exhaust flow, often dropping exhaust gas temperatures by up to 10.8 °F for cooler turbo operation and extended turbocharger life.
Improving Power and Response
By removing OEM restrictions such as the EGR system and CCV, airflow improves significantly. This enhancement leads to better combustion efficiency, resulting in noticeable gains in horsepower and torque. Additionally, the reduction of carbon buildup contributes to quicker turbo spool-up and improved throttle response. Re-mapping the ECM after these deletions can further optimize performance while maintaining safe exhaust gas temperatures.
Mitigating Common Failures
1. VGT Turbine Failures (2011–2014): Ceramic bearings in early turbos often failed (DTC P2263/P0299). A straight-through exhaust reduces heat soak and helps preserve turbine life.
2. CCV/PCV Clogging: OEM separators clog, causing high crankcase pressure. Aftermarket CCV delete or reroute kits prevent blow-by(oil-laden crankcase vapors) from re-entering the engine, helping to reduce carbon buildup and improve long-term performance.
3. EGR Cooler Deposits (DTC P0401/P0402): Combustion particulates foul the cooler. An aftermarket EGR delete kit removes the cooler and replaces it with a precision-machined block-off plate for leak-free sealing.
Proven Performance That Pays Off: Every EngineGo delete kit and exhaust system undergoes rigorous dyno testing and real-world road trials to deliver measurable horsepower and torque gains, so you not only feel the difference but also save time and money on downstream repairs and maintenance.
What EngineGo Can Help with Your 6.7 Powerstroke Delete Job
EngineGo offers a complete suite of delete solutions—delete pipes, EGR delete kits, and CCV delete kits—designed to restore lost performance, eliminate clogging, and streamline your truck’s exhaust and crankcase ventilation systems.
Delete Pipes
Our delete pipe lineup spans from simple DPF/DEF/CAT removal pipes to full turbo-back or downpipe-back straight exhaust systems.
- DPF/DEF/CAT Delete Pipes
What it solves: Removes the restrictive Diesel Particulate Filter, DEF injector plumbing, CAT(actually DOC), cutting back-pressure to improve back-road horsepower and reduce costly filter regenerations.
- Turbo-Back Straight Pipes
What it solves: Bypasses OEM downpipe and mid-pipe restrictions, offering maximum exhaust flow from turbo outlet to tailpipe—ideal for aggressive tuning, reduced turbo lag, and cooler EGTs.
- Downpipe-Back Straight Pipes
What it solves: Eliminates only the downpipe and all factory exhaust-aftertreatment downstream, for a simpler install that still delivers major gains in flow, sound, and reliability.
EGR Delete Kit
What it solves: Blocks the Exhaust Gas Recirculation (EGR) cooler and valve to prevent soot buildup, which leads to clogged coolers, poor idle quality, and increased maintenance. Our precision-machined block-off plates and leak-proof gaskets eliminate that failure point entirely.
CCV Delete Kit (PCV Reroute)
What it solves: The stock Crankcase Ventilation (CCV/PCV) separator often clogs with oil and soot, causing high crankcase pressure, oil consumption, and seal failures. EngineGo’s reroute kit diverts crankcase blow-by away from the intake system, preventing them from re-entering the engine—ensuring clean venting and extending engine life.
