The turbo adapter on stock Ford F-150 / Raptor Ecoboost engines is recognized as a flow restriction in the exhaust system.
A new stainless steel casting enhances the OEM part with an enlarged cross-section and a smooth taper that aligns with the oval-shaped turbo outlet, ensuring a seamless transition for airflow into the downpipe.
The volume of the flow section increases from 9.8 to 10.1 cubic inches, while the minimum internal cross-sectional area expands from 3.4 to 4.2 inches, a 23% increase.
This design, aided by CAD Flow Simulation, maximizes flow while maintaining sufficient material to withstand exhaust heat and pressure.
The turbo side pressure is reduced by 55.8% from stock levels, while velocity increases to 101.1% of stock, smoothing out the flow.
This results in more power being applied to the wheels by the engine, rather than forcing air through the exhaust, leading to improved top-end power and reduced spool time, especially noticeable under high airflow conditions.
