Universal: Fits any 60mm Standard V-Band Wastegate Port 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. Wastegates are bolted to the exhaust manifold or header. The advantage of external Wastegates is that the bypassed flow can be reintroduced into the exhaust stream further downstream of the turbine. This tends to improve the turbine’s performance.
