The turbocharger center section, also known as the CHRA (Center Housing Rotating Assembly), is the heart of your turbo system. It houses the turbine and compressor wheels, along with their respective shafts, all precisely balanced to spin at extremely high speeds. This component is engineered to withstand high temperatures and pressures generated during the turbocharging process. A properly functioning center section ensures efficient exhaust gas flow through the turbine and optimal air intake into the engine, leading to increased power and improved fuel economy. When experiencing issues like reduced power, excessive smoke, or unusual noises from your turbo, the center section is often a key area to inspect. Replacing a worn or damaged CHRA can restore your turbocharger's performance to its original specifications.
