46mm Wastegate with Race Proven Reliability!

The wastegate that started it all. This unit was developed as a bolt in replacement unit for the Porsche 930. Constructed from high temperature alloys for the valves and lower housings, CNC machined billet aluminum actuator housings and Nitronic 60 valve guides and seats. These high temperature materials were selected for their unique combination of high corrosion, wear and galling resistance properties. The billet aluminum actuator housing is lightweight and available anodized in silver, black, red, blue or purple. Inside is a 17-7 PH stainless steel actuator spring capable of consistent pressure at elevated temperatures. The TiAL F46P Wastegate spring base pressures range from 2.90 to 20.31psi (0.2 to 1.4 bar). These Wastegates feature machined sides for Porsche 911 Turbo fitment. All TiAL wastegates are designed to optimize actuator-to-valve area ratio to provide maximum control and a wide dynamic flow capacity.
