F46P.4P Wastegate 46mm Porsche .4 Bar (5.80 psi) Purple

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. Features: High temp NiCrFe based alloy is used for valve and 347SS valve housing will offer longer product life compared to competing designs High temperature silicone Nomex reinforced actuator diaphragm 17-7 PH Stainless Steel actuator spring gives consistent pressure at high temps, resist ''relaxing'' at temperature to 900°F (483°C) Nitronic 60 Stainless Steel is used for the valve seat, and valve bushing All Stainless Steel hardware Inlet Flange: 1.625'' OD; Outlet Flange: 1.625'' OD 1.772'' square center-to-center 4-bolt hole flange Mating weld flanges are 304L Color anodized aluminum actuator (Silver, Red, Blue, Purple, Black) Included with Every Tial F46 Series Wastegate: F46 Wastegate Assembly F46 Valve Seat Two TiAL Air Fittings Eight SS Allen Head Bolts and Washers Two Gaskets
