GFB EX44 - external 44mm Wategate

The GFB EX4 external wastgate was developed to handle the most extreme exhaust gas temperatures with ease.

The EX44 not only supports an optimum flow rate, but is also characterized by its compact size,
which is unattainable by comparable 44mm Wastgates from other manufacturers.

Properties:
Equipped with a 15psi spring
Springs with 7psi (0.49 kg/cm2) and 9psi (0.63 kg/cm2) are also available and can be combined with the 15psi spring.
The following charging pressures can therefore be achieved: 0.5, 0.6, 0.9, 1.1, 1.4, 1.5, 2.0 bar (7, 9, 13, 16, 20, 22 and 29psi)
The housing, valve and seat are made of high-temperature resistant steel.
The drive housing is made of 7075 aluminum, which is much stronger and harder than ordinary 6061 aluminum.
Flow tests have shown that the GFB EX44 is up to 18% superior to competing wastegates with the same valve lift.
The internal valve cover protects the valve stem from excessive heat and thus prevents sticking.
The Nomex-reinforced silicone rolling diaphragm provides more valve lift.

Scope of delivery : 90° banjo connections, V-band clamp mounting system, with 304 stainless steel weld-on adapter
(Base flange is compatible with TiAl 44 flange when used with the GFB adapter).
