Aurora 4000 Turbocharger

The ATS Aurora 4000 Turbo System is an upgraded turbocharger meticulously engineered for the 2003-2007 Dodge 5.9L Cummins platform. Featuring a 63mm inducer compressor wheel, this turbo represents a substantial performance leap over the factory unit. It is designed to support up to 600 horsepower, provided appropriate fuel system modifications and advanced tuning are implemented. The system is capable of efficiently operating at 40 psi and above, maximizing air volume for a more complete and efficient combustion process within the cylinders. This enhanced combustion leads to a reduction in Exhaust Gas Temperatures (EGTs) under load, enabling higher sustained horsepower output and a more potent, efficient torque curve. The billet compressor wheel is constructed for exceptional durability, capable of withstanding higher pressure ratios without experiencing fin deflection or fatigue, and maintaining its form even after prolonged exposure to extreme heat cycles. Key features include a ported compressor housing design to reduce turbo bark, excellent spool time for responsive low-end torque, and an estimated 150-200 degree Fahrenheit drop in EGTs. The system boasts a 1190 CFM flow rate and includes all necessary hardware for installation, making it a comprehensive kit for a significant performance upgrade. The Aurora 4000 Turbo System is specifically designed for the 2003-2007 Dodge RAM 2500/3500 models equipped with the 5.9L Cummins engine.
