The AFE Power L5708303 is a ball-bearing turbocharger, which is known for its durability and ability to handle high boost levels. It features a compressor wheel with an increased diameter that provides increased airflow and improved volumetric efficiency. As a result, this turbocharger delivers more power throughout the RPM range.
Moreover, the turbine wheel of this turbocharger is designed with more blades than the original equipment manufacturer's (OEM) turbocharger, which helps to reduce turbine inlet temperature (TIT) and extract more energy from the exhaust gas. A lower TIT translates to increased reliability and longer-lasting performance.
The AFE Power L5708303 also boasts a larger wastegate and an upgraded exhaust housing. These upgrades help to improve spool-up time, providing a more responsive driving experience. Additionally, the wastegate is adjustable, allowing for fine-tuning of the boost levels to achieve optimal engine performance.
This turbocharger comes with a new, high-performance, lubrication system that includes a high-capacity oil pump and a larger oil cooler. These upgrades ensure that the turbocharger is properly lubricated and cooled, even under heavy loads, resulting in longer-lasting performance and increased reliability.
Overall, the AFE Power L5708303 is a high-quality, high-performance turbocharger that delivers increased power, improved torque, and better response times for the GMC Sierra 3500 Duramax models from 2001 to 2004. It is a must-have upgrade for anyone looking to maximize the potential of their diesel engine.
