ATS Aurora Compound Turbo Upgrade 19-24 Ram 6.7L Cummins

Are you looking to unlock the full potential of your 6.7L Cummins? The ATS Aurora Compound Turbo Upgrade is a full twin-turbo system designed for Ram trucks that have outgrown what a single turbo can realistically deliver. Instead of forcing one turbo to handle both quick spool and high horsepower demands, this compound setup splits the workload between a high-pressure VFR turbo and a larger Aurora low-pressure turbo. The result is a near-instant response off the line, aggressive mid-range torque, and the airflow capacity to keep pulling hard up top without falling flat. Where this setup really stands out is under load. Whether you’re towing heavy, racing, or running a tuned street truck, compound turbos dramatically improve efficiency by reducing exhaust gas temperatures (EGTs) while increasing usable boost across the entire powerband. That means less heat stress on the engine, more consistent power delivery on long pulls, and a truck that feels controlled instead of strained when you’re in it hard. It also eliminates much of the “either/or” compromise of single-turbo upgrades; this system gives you spool and top-end at the same time, rather than choosing one over the other. Built around ATS’s Aurora and VFR turbocharger architecture, this system uses precision-cast housings, upgraded compressor and turbine wheel designs, and heavy-duty internal components engineered to survive sustained high boost and elevated exhaust temperatures. The low-pressure turbo is designed to move serious air volume efficiently, while the high-pressure unit maintains quick response and tight control at lower RPMs. This balance allows compound systems to support up to 750hp/1400ft lbs of torque. The kit is engineered as a complete bolt-on system with a dedicated compound manifold, properly routed charge piping, and supporting hardware designed for clean integration on the 6.7L Cummins platform. Thermal management is also a major focus, with coated turbine housings and optimized flow paths that help retain energy in the system where it’s needed while reducing unnecessary heat soak. The oil and coolant routing is designed for long-term durability under continuous load, making it suitable for towing-heavy builds as well as performance-focused street trucks. Overall, this upgrade isn’t just about adding power; it completely changes the way the engine breathes and responds. Instead of pushing a single turbo beyond its efficient range, the compound layout keeps both turbos operating in their optimal zones, resulting in stronger towing performance, more consistent power delivery, lower EGTs, and a much wider usable powerband across real-world driving conditions.
