BCS Options

The Cortex EBC Complete Kit is available with either a 3-port or 4-port boost control solenoid (BCS) to match the boost control requirements of your specific application.

A 3-port solenoid is recommended for most users.  They are easy to tune, provide very precise boost control, and are capable of producing boost levels 2 to 3 times greater than wastegate spring pressure on most applications.

The 4-port solenoid is available for applications that need to achieve a very wide range of boost levels based on gear or vehicle speed.  They can be more difficult to tune than a 3-port solenoid, but can produce boost levels that are 4 or more times higher than wastegate spring pressure on most applications.  For additional information on how this type of solenoid controls boost see the 4-Port BCS product page.

3-PORT BCS OVERVIEW

• Compatible with internal and external wastegates.
• Used to control pressure application to a single wastegate port.
• Provides better control accuracy and resolution than 4-Port BCS.
• Capable of producing boost levels at least 2 times greater than wastegate spring pressure on most applications.
• Limited ability to counteract boost taper caused by exhaust manifold back pressure without the use of compressed air.

4-PORT BCS OVERVIEW

• Compatible with external wastegates or dual port internal wastegates.
• Used to alternate pressure application between two wastegate ports.
• Has reduced control accuracy and resolution compared to 3-Port BCS.
• Capable of producing boost levels at least 4 times greater than wastegate spring pressure on most applications.
• Extremely effective at counteracting boost taper caused by exhaust manifold back pressure.
• Can also be used in 3-port BCS configuration by plugging one of the ports.
