Full-Race 4 Port MAC Boost Control Solenoid
Full-Race 4 Port MAC Boost Control Solenoid w/ Full-Race Bracket
Our 4-port boost control solenoid valve is designed to target a clearly defined boost curve and improve boost responses, and in some cases with a soft WG spring – quicker spool. The 4-port design works equally well in low boost applications and high boost. This differs from a traditional 3-port BCSV because it precisely directs pressure to the open and close ports of your wastegate diaphragm. This allows much lower wastegate spring pressure for better low gear boost control and perfect high gear, high boost control.
Full-Race 4 Port Boost Control Solenoid Features:
A soft waste-gate spring will enable much higher boost levels
Better spool-up and mid range power
Better duty cycle control
Solenoid is normally closed so that on failure you will run off the waste-gate spring only – to prevent over-boosting.
1/8th NPT fittings, easily adapted to AN fittings. Please contact us to order an AN conversion kit.
Full-Race 4 Port Boost Control Solenoid Compatibility:
Ideal for use in sealed Dual Port Internal WG applications, Internal or External
Hondata S300, K-Pro or Flashpro
Cobb Tuning AccessPort
All PWM modulated standalone and piggyback ECU’s will support this 4 port BCSV!
Note: 4 Port MAC Boost Control Solenoid must be mounted upside down on B2 EFR frames.
This allows the exhaust port to point towards the wastegate nipple.
