Turbo Outlet Adapter Kit Ford F-150 (2011-2020)

The stock turbo adapter on the Ford F-150 / Raptor EcoBoost motors is a known restriction in the exhaust flow. PRL's new design improves on the OEM piece by starting with a fresh stainless steel casting. The design has an increased cross section with a smooth taper that is matched to the oval-shaped turbo-side opening, making a seamless transition as air flows from the turbo into the downpipe. Total volume of the flow section is increased from 9.8 to 10.1 in³, and the minimum internal cross-sectional area is increased from 3.4 to 4.2 in², a 23% increase.

This design was chosen with the aid of CAD flow simulation, with the goal of maximizing flow while maintaining enough material to handle the heat and pressure of the exhaust gasses. Simulation results show the increased flow area reduces turbo-side pressure 55.8% from stock while increasing and smoothing velocity to 101.1% of stock. Faster, easier flow means the motor can apply more power to the wheels instead of forcing air through the exhaust—most noticeable at higher RPM for increased top-end power and lower spool time.

Performance Testing

Dyno testing showed a +14 HP and +1 lb-ft peak gain, with torque peaking 212 RPM earlier than stock. Max gain is +30 HP at 5300 RPM and +23 lb-ft at 5600 RPM. Peak boost pressure also increased from 20.8 to 21.77 psi, building quicker and hitting peak at 3273 RPM versus 3379 RPM stock.
