The Duramax diesel engine has earned a reputation for its power and performance, especially in heavy-duty trucks. One of the most significant upgrades you can make to enhance performance is the turbocharger. In this article, we will compare the stock Duramax turbo with the ATS Aurora 64mm turbo to determine which one provides better performance and value for your vehicle.
Understanding Turbochargers
A turbocharger is a device that forces extra air into the engine’s combustion chamber, allowing for more fuel to be burned and thus increasing power output. The efficiency and size of the turbocharger significantly impact the overall performance of the engine.
Stock Duramax Turbo Overview
The stock turbocharger for the Duramax engine is designed to provide a balance between performance and reliability. It is engineered to work well with the factory tuning and offers good power output for everyday driving. However, it may not meet the demands of high-performance applications.
Specifications of the Stock Turbo
- Compressor Wheel Size: 60mm
- Max Boost Pressure: 30 PSI
- Power Output: Up to 500 HP
- Designed for Stock Fueling
ATS Aurora 64mm Turbo Overview
The ATS Aurora 64mm turbo is a popular upgrade for Duramax enthusiasts looking to increase power and efficiency. This turbocharger is designed to provide improved airflow and boost pressure, making it suitable for modified engines and performance applications.
Specifications of the ATS Aurora 64mm Turbo
- Compressor Wheel Size: 64mm
- Max Boost Pressure: 40 PSI
