From: Northeastern Pa - USA

they regulated the boost pressure using a "wastegate actuator". Looks like a little can connected to the turbine housing with a metal rod and a hose on it. It is internally spring loaded (closed) and the spring pressure is overcome by the boost pressure, fed thru a little hose to the actuator. When about 7 psi of boost is produced, the actuator opens the gate and releases excess pressure to the exhaust system.
