SpeedFactory Racing 3-Port Boost Control Solenoid Kit
The SpeedFactory Racing 3-Port Boost Control Solenoid Kit allows precise boost control with a PWM (pulsewidth modulation) signal from a source (Engine Control Module or Electronic Boost Controller). This solenoid can raise the boost level as high as 2-3 times the spring pressure of the wastegate. (For higher boost levels and better off-the-line boost control please see our 4 Port Boost Control Solenoid Kit). This kit can be used with single or multiple wastegates, and is compatible with almost every electronic boost controller and tuning software. This product can be used with internal or external wastegates. 34Hz is our suggested starting point for control frequency in your EMS, and gives stable control in MOST setups. This is a maximum boost at 100% duty/normally closed solenoid. Finding the correct control frequency to achieve stable boost control for your particular EMS and setup is part of proper boost control tuning. Improper control frequency will result in unstable boost contro
