Boost Solenoid 3 port
Boost Solenoid 3 port
A boost control solenoid is pivotal in regulating airflow to the wastegate of turbocharged engines. Its primary function is to prevent over-boosting by opening the wastegate valve to release excess exhaust gases.
Guidelines:
- With a 3-port valve, you can adjust the wastegate spring pressure by a factor of 2 to 2.5 times.
- With a 4-port valve, this can increase to a factor of 5 to 6.5 times.
