Application: Wastegates provide a means to control the boost pressure of the turbocharged engine. Wastegates work to bypass exhaust flow from the turbine wheel. Bypassing the exhaust flow reduces the power of driving the turbine wheel to match the power required for a given boost level. Similar to the BOV, the Wastegates use boost pressure and spring force to regulate the flow bypassing the turbine.

Q1: What is the Wastegate made of? Is it stainless steel?

  • A1: The bottom of the main body is made of stainless steel, and the top is made of aluminum alloy.

Q2: Does this kit require spring-assisted installation?

  • A2: No, the springs are pre-installed. If you have specific requirements for the spring coefficient, you can purchase additional springs for replacement.

Q3: Do I need to add thread sealer?

  • A3: Yes, adding thread sealant is recommended to ensure a better seal.

Q4: Can this work with CO2 boost control?

  • A4: While it may not be specifically designed for CO2 boost control, any wastegate can be used with CO2 boost control. It makes no difference whether using boost pressure or CO2 gas pressure to add to the poundage of the spring.
