Application Scenarios

Engineered for high-performance durability, the S480 turbocharger integrates with S400SX4 twin-scroll systems to enhance power delivery in heavy-duty and high-output applications. Its twin-scroll design improves exhaust pulse separation, maximizing energy recovery and reducing boost threshold for rapid throttle response. This makes it ideal for commercial trucks requiring quick acceleration, construction equipment operating under variable loads, and marine vessels needing high torque at low RPM. With its single OEM equivalent (171702), this turbocharger simplifies parts sourcing for mechanics, reducing downtime through quick installation and US-based inventory availability. Each unit undergoes rigorous dynamic balance testing to ensure smooth operation and minimal vibration, supporting extended engine lifespan in high-performance T4-powered vehicles.
