What This Wastegate Actually Does

An external turbo wastegate controls boost by diverting exhaust around the turbine once the desired boost pressure is reached. The 60mm valve provides substantial exhaust bypass capacity to help maintain controlled boost and reduce the potential for boost creep on properly designed turbo systems.
