Precision 46mm Wastegate including 3 different stiffness springs, both V-Band Flanges, Clamps, and all installation hardware. This wastegate will bolt on to an existing Tial 44mm Wastegate flange, but has a 2mm larger valve opening so it will flow more. Its a bolt on upgrade for current Tial 44mm users.

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.
