Turbosmart PSG50CG 7PSI Compressed Gas Solenoid Pneumatic StraightGate50 - Black for 1998-2005 VW/Audi 1.8T
The Turbosmart PSG50CG 7PSI Compressed Gas Solenoid controls the StraightGate50 wastegate actuator on 1998-2005 VW and Audi 1.8T models with K03 or K04 turbos. It replaces factory solenoids using compressed gas for direct pneumatic operation and fast boost control. This delivers consistent boost across all RPM ranges for reliable street and track performance.
Key Features
- Billet Construction: Machined from 6061-T6 aluminum with black anodized finish resists corrosion and high-heat turbo environments
- 7 PSI Operation: Runs on compressed CO2 or N2 gas supply for independent actuator control without boost pressure dependence
- Tri-Port Design: Three 1/8 NPT ports for gas supply vent and actuator connection handle high-flow rates for quick valve response
- Fast Response Solenoid: PWM-compatible valve actuates in milliseconds to reduce boost lag and sharpen throttle response
- Plug and Play Wiring: Includes harness matching Turbosmart StraightGate50 for seamless integration with stock or aftermarket ECUs
Product Notes
