Compound turbochargers from the factory. What a wild concept that Ford included in their 2008-2010 6.4 Powerstroke. Say what you will about the the notorious 6.4, these things can make monster power! This is how you make that kind of power, with our KC Fusion compound turbo set up! The high pressure turbo essentially spools up fast and then feeds the low pressure turbo. The Low pressure turbo then re-compresses the boost to make even more boost and Horsepower.

We have worked on our KC Fusion compound turbo set up for several years, changing, upgrading and perfecting the product. now it is ready for all to enjoy. This compound turbo set up is meant for those who want to really open up the raw power of the 6.4 Powerstroke. This turbo set up is recommended for those who want a big boost in performance, but still have the option of light towing.

**EXHAUST BRAKES: We get asked a lot about exhaust brakes and if they work with our turbos. We have 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 aide in braking. This can be hard on a turbo and motor and is not recommended. It will be up to the customer to verify fitment and functionality.**

***REQUIRES upgraded 4" intake to fit over upgraded 4" inlet
