Full Race - 4 Port MAC Boost Control Solenoid

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.

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

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. Please see the photo below for reference.
