Industrial Injection 07.5-09 Dodge S471 Cummins w/1.10 Turbine A/R Turbo Kit (177248)

This Industrial Injection S471 turbo kit is built around a 1.10 A/R turbine housing, a choice that helps manage exhaust gas flow for improved performance on your 2007.5-2009 Dodge Cummins. When you're looking to upgrade your truck's forced induction system, a well-matched turbocharger can make a significant difference in how your engine breathes and performs, especially under load. This kit is designed to provide a substantial airflow increase over the stock unit, helping your engine produce more power and torque.

Industrial Injection has put together this kit with the Cummins owner in mind, focusing on components that work together to deliver reliable performance. The S471 designation indicates a specific compressor and turbine wheel size combination, chosen to balance airflow and responsiveness. The 1.10 A/R (Area/Radius) ratio on the turbine housing is particularly important; a larger A/R like this one generally allows for better exhaust flow at higher RPMs, which can help prevent exhaust backpressure from choking the engine when it's working hard. This means you can potentially see improved top-end power and a broader powerband.

This turbo kit is a significant upgrade for your Cummins. It's important to note that this kit is not CARB approved and cannot be shipped to California. Proper installation and supporting modifications, such as an upgraded exhaust and fuel system, may be necessary to fully realize the potential of this turbocharger and ensure its longevity. Always consult the manufacturer's installation guide for specific recommendations and requirements.
