PSG50V Pneumatic Straight Ext. Wastegate

The PSG50V Pneumatic Straight External Wastegate by TURBOSMART USA is a precision boost control component engineered for forced induction systems requiring reliable, adjustable wastegate function. This externally mounted unit addresses the core challenge every turbo builder faces: managing boost pressure consistently across the RPM band without sacrificing engine safety or drivability. Whether you're tuning a street performance build or developing a competition engine, the PSG50V delivers the pneumatic response necessary for repeatability and fine-tuned boost control that mechanical-only solutions cannot match.

This straight-external design utilizes pneumatic actuation to modulate wastegate opening, allowing boost to build progressively and prevent overboosting conditions that risk turbo failure or detonation. The PSG50V integrates seamlessly with aftermarket boost controllers and standalone ECU systems, accepting pneumatic input signals that command gate position with high resolution. Its compact yet robust construction—measuring 7 x 5.25 x 8.5 inches and weighing 4.13 lbs—minimizes packaging constraints while maintaining the structural integrity required for high-boost applications. Turbosmart's proven material selection and seal engineering ensure durability across extended dyno sessions and track duty without performance degradation.

Turbo enthusiasts, engine builders, and tuners benefit most from the PSG50V when building single or twin-turbo systems that demand closed-loop boost control and repeatability. This wastegate excels on naturally aspirated engines converted to forced induction, custom LS builds, and any application where aftermarket boost management is desired over OEM solutions. Installation requires proper exhaust manifold porting and pneumatic line routing to your boost controller; ensure your tuning platform supports pneumatic wastegate commands. The PSG50V (MPN TS-0565-1212) pairs effectively with standalone engine management systems and quality boost controllers, making it a staple choice for builders prioritizing precision over simplicity.
