A system designed for Ford trucks equipped with a 6.7-liter Powerstroke diesel engine, this modification involves integrating two turbochargers that work in sequence. One turbocharger pre-compresses the air before it enters the second, larger turbocharger, resulting in increased overall boost pressure. This type of forced induction can significantly enhance engine performance in terms of horsepower and torque output. A typical installation includes the turbochargers themselves, along with necessary piping, intercooler upgrades, and potentially fuel system modifications to support the increased airflow.
The advantage of this setup lies in its ability to provide more power throughout the engine’s RPM range, addressing limitations often encountered with single turbocharger configurations. Historically, performance enthusiasts and those requiring increased towing capacity have gravitated towards these systems. Benefits extend to improved throttle response, reduced turbo lag, and the potential for greater overall engine efficiency when properly tuned. The improved power delivery can make a significant difference in demanding applications like hauling heavy loads or navigating challenging terrain.
