The center section, also known as the CHRA (Center Housing Rotating Assembly), is the heart of your turbocharger. It houses the turbine and compressor wheels, along with their respective shafts and bearings. This component is meticulously engineered to withstand high temperatures and rotational speeds, ensuring optimal boost pressure and power delivery. A properly functioning center section is vital for maintaining engine efficiency and responsiveness. When experiencing issues like reduced power, excessive smoke, or unusual noises from your turbo, the center section is often the culprit. Replacing it with a quality unit like this KAMOKA part can restore your turbo's performance and reliability.
