UNIVERSAL EXTERNAL 14-PSI 45MM TURBOCHARGER V-BAND 5.25"WASTEGATE+SPRING GOLD

Wastegates provide a means to control the boost pressure of the turbo charged engine. Wastegates work to skip over exhaust flow from the turbine wheel. Skipping over the exhaust flow reduces the power driving the turbine wheel to match the power required for a given boost level. Similar to the BOV, the Wastegates uses boost pressure and spring force to regulate the flow skipping over the turbine. Wastegates are bolted to exhaust manifold or header. The advantage of external Wastegates is that the skipped over flow can be reintroduced into the exhaust stream further downstream of the turbine. This tends to improve the turbine's performance.
