Product Description
The ATS 202-A47-2272 Aurora 4000/7500 Compound Turbo System is a high-performance twin turbo upgrade designed for 2003-2007 5.9L Cummins engines. This compound setup combines the quick-spooling Aurora 4000 with the high-flow Aurora 7500 to deliver massive airflow, improved throttle response, and exceptional top-end power.
By pairing a smaller high-pressure turbo with a larger atmospheric turbo, this system eliminates turbo lag while dramatically increasing horsepower capability. The result is smooth power delivery across the entire RPM range, making it ideal for towing, street performance, and competitive applications.
Engineered for durability and efficiency, this ATS compound system improves exhaust gas temperatures (EGTs), increases boost efficiency, and supports high horsepower builds without sacrificing drivability.
FAQ
Q: What is a compound turbo system?
A: A compound turbo system uses two turbos working together—one for quick spool and one for high airflow—resulting in better performance across the entire powerband.
Q: What are the benefits of this setup?
A: Faster spool-up, reduced turbo lag, increased horsepower potential, and improved towing performance with lower EGTs.
Q: Is this system good for towing?
A: Yes, compound turbos are excellent for towing because they provide strong low-end torque while maintaining cooler exhaust temperatures.
Q: Are supporting modifications required?
A: Yes, upgraded fueling, tuning, and supporting drivetrain components are recommended to fully utilize this system.
