Tial 60mm Wastegate. This is not a fake or a copy. We only sell genuine Tial products. BLACK, RED, BLUE, and PURPLE are also available if requested HOWEVER REQUESTING A COLOR OTHER THAN SILVER COULD DELAY THE ORDER UP TO 2 WEEKS BEFORE SHIPPING. We usually ship .751 - 1.408 bar wastegates but if availability is limited we will sometimes ship the next closest size to eliminate lengthy wait times. If it is important that you get an exact spring pressure or if you specifically need another spring, please email us and let us know before payment. Wastegates are an essential part of any turbocharged powerplant. Controlling boost not only ensures that you are maintaining the correct pressures for the fuel you are running, but it also prevents overboost situations where the turbocharger is forced to spin faster than it would like. In these instances, you actually can loose horsepower, as the air is being super-heated by the compressor. This TiAL unit will handle boost control duties flawlessly when placed in a well designed system. This wastegate comes standard with TiAL's racing valve stem. The valve stem has a wear coating on it which is resistant to corrosive lead oxides that appear when running leaded racing fuels.
