Performance & Application

This turbocharger is designed for high-horsepower builds where large-frame airflow and ball bearing responsiveness are non-negotiable. The built-in ported shroud (anti-surge) technology extends the usable compressor map, improving stability at high boost while resisting surge under aggressive tuning conditions. The T4 un-divided turbine inlet paired with a V-band outlet delivers efficient exhaust flow for setups pushing well past 1,100 horsepower. This is a large-frame turbo best suited for dedicated, high-output performance applications rather than mild street builds.
