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. The classic 2 bolt flange wastegate. We first produced the F38 back in 2001 and it's still going strong today. This wastegate has a 38mm valve - same as the MV-S, and its body is about an inch taller.
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 temperature, resist "relaxing" at temperature to 900F (483C).
Nitronic 60 Stainless Steel is used for the valve seat, and valve bushing.
All Stainless Steel hardware.
Mating weld flanges are 304L or 1018
TiAL's F38 is equipped with the racing valve stem. The Wear Coating is resistant the the corrosive effects of Lead oxide which is present when running leaded racing fuel.
