If you’re looking to unlock serious power from your CAT 3406E or C15, the PDI BIG BOSS® Compound Turbo Kit is built to deliver the airflow and performance needed for high-horsepower applications.
Designed for engines pushing 600–800 horsepower, this compound turbo system pairs two turbos together to dramatically improve airflow and boost efficiency. By staging the turbos, the system helps maintain strong boost across the RPM range, delivering quicker spool-up, stronger pulling power, and improved overall engine performance.
When combined with PDI engine tuning and customization, the BIG BOSS® Compound Turbo Kit helps maximize the full potential of your engine. The improved airflow and boost control allow your engine to produce more power while maintaining better efficiency and drivability.
