2008-2010 Powerstroke KC Fusion Compound Turbochargers (Stage 1 High Pressure & Stage 1 & 2 Low Pressure) (302448)

Fits

To achieve optimal power for your 6.4L Powerstroke, consider the KC Fusion compound turbo setup! The high-pressure turbo quickly spools and transfers to the low-pressure turbo. The Low-pressure turbo then re-compresses the boost, increasing boost and horsepower.

Now perfected by KC Turbos, this turbo setup is recommended for those who want a big boost in performance, but still have the option of light towing.

• EXHAUST BRAKES:  KC Turbos gets asked a lot about exhaust brakes, and if they work with KC Turbos, these will retain the OEM feature if the vehicle's calibration allows and is set up for it. KC Turbos has found that some brands have clearance issues and might cause the brake to hinder performance, rub the turbine wheel, or cause other issues.  These brakes typically use some sort of flapper to close, which causes extreme exhaust back pressure to aid in braking.  This can be hard on a turbo and motor and is not recommended.
