TURBOSMART PSG50 external wastegate, 6 inHg

The TURBOSMART PSG50 (Pneumatic StraightGate50) external wastegate with a zero-offset butterfly valve offers very high flow and almost linear boost control. This version is controlled by a vacuum-based GenV actuator set to 6 inHg. Vacuum-based control allows advanced gate strategies, such as being fully open at cold start for better emissions compliance, and works with some OE boost control systems originally fitted with vacuum-based internal wastegate actuators.

• Zero-offset butterfly valve pivoting centrally
• Self-balancing against exhaust drive pressure, wide tuning window
• Vacuum-based GenV actuator, 6 inHg
• Single and twin port control, including boost-assist
• Higher flow from a straight-through valve, a poppet valve turns the exhaust gas through 90°
