Link ECU G4+ G4X 4 four port Boost Control Solenoid - 1/8 NPT 4 Port

Link 4-Port Boost Control Solenoid

The Link 4-Port Boost Control Solenoid provides precise electronic boost control for high-boost turbocharged applications.

It is suitable for internal and external wastegates, including single and multiple wastegate configurations, and offers a wider boost control range than a conventional 3-port solenoid.

When configured correctly, boost levels can reach approximately 6 to 7 times the base wastegate spring pressure.

Suitable Applications

Compatible with:

• All Link ECUs

• Internal wastegates

• External wastegates

• Single wastegate setups

• Multiple wastegate setups

• Open Loop Boost Control

• Closed Loop Boost Control

• High-boost turbocharged applications

For applications that do not require the wider boost range of a 4-port setup, a 3-Port Boost Control Solenoid may be more suitable.

Installation Requirements

The solenoid requires:

• Spare ECU Auxiliary Output switched to ground

• 12V ignition-switched power supply

• MAP sensor

• Open Loop or Closed Loop Boost Control configured in the ECU

No additional standalone boost controller is required.

Key Features

• 4-port electronic boost control solenoid

• MAC 45 Series

• Maximum pressure of 120 PSI

• Suitable for internal and external wastegates

• Suitable for single or multiple wastegate configurations

• Fast and consistent response

• High shifting force

• Short-stroke, high-flow design

• Balanced poppet design

• Resistant to pressure variation

• Rugged construction

• Long operational life

Boost Control

Depending on the wastegate and turbocharger setup, a 4-port solenoid can allow boost pressure to reach approximately 6 to 7 times the base wastegate spring pressure.
