What is a 3-inch Anti-Surge Cover?

An anti-surge compressor housing, like the 3-inch cover on these Kinugawa turbos, is engineered to prevent a condition known as compressor surge. This occurs when the turbocharger is producing more air than the engine can ingest, leading to a backflow of air and instability in boost pressure. This can be particularly damaging to the turbocharger's bearings and compressor wheel.

The anti-surge cover features a ported design with slots or holes that allow the excess pressure to be recirculated within the compressor housing. This helps to stabilize the airflow, move the surge line on the compressor map, and allow the turbo to operate efficiently and safely, especially under high-boost conditions. In essence, it's a critical feature for anyone looking to push their EVO 10 X to higher performance levels while maintaining the longevity of their turbocharger.
