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
- Compressed gas bottle and regulator sold separately
- Pair with Turbosmart StraightGate50 wastegate for complete setup
- Securely packaged to prevent shipping damage
Installation Notes
- Professional installation recommended.
- Mount solenoid within 12 inches of wastegate actuator using provided bracket
- Requires 1/8 NPT fittings and compatible PWM ECU signal

Forced Induction
Forced induction systems encompass every method of pushing air into an engine at greater than atmospheric pressure, including turbochargers driven by exhaust energy, superchargers driven mechanically by the crankshaft, and prochargers using centrifugal designs belt-driven at higher ratios than traditional roots-type blowers, with each approach delivering a significant increase in air mass per cylinder fill that allows proportionally more fuel to be burned and more power to be produced without increasing engine displacement. Adding 10 PSI of boost pressure to a naturally aspirated engine can increase power output by 50 to 70 percent depending on the engine's breathing efficiency and the quality of the supporting hardware, making forced induction the most power-dense modification available relative to cost and complexity. This collection covers complete forced induction systems, turbocharger and supercharger hardware, intercoolers, blow-off valves, wastegates, and supporting component...
