RECOMMENDATIONS FOR MOUNTING YOUR ULTRA-GATE38
The mounting position of your Ultra-gate38 will be largely determined by your turbo and manifold setup and may be constrained by
space restrictions in your engine bay. The following points should be considered when mounting your Ultra-gate38.
-
The optional exhaust weld flanges should be
welded to your exhaust system. The weld flanges
are compatible with Stainless Steel and Mild steel
welding rod material.
-
When securing your Ultra-Gate38 use the supplied
gaskets between the weld flanges and the
inlet/outlet flanges. Use the M8X25 screws to
secure the outlet flange (Note: The bolts screw into
the threaded holes on the outlet flange). Use the
M8 nuts and M8X35 screws if needed to secure
inlet flange to your manifold (Note: Your manifold
may have studs to suit so the screws may not be
necessary). Tighten the screws and nuts to a
torque of 8 Nm & lubricate with Never Seize every
time you re-fit the wastegate.
PORT BLANKING PLUGS AND PRESSURE NIPPLES
The Ultragate38 is supplied with 2 X 1/16NPT nipples and 2 X 1/16 NPT plugs. These are installed in the lower and upper diaphragm
housings depending on the boost control hook up to create an air tight volume above or below the diaphragm so that air pressure can
control valve movement. Single port hook ups require a nipple and plug to be installed only on the lower diaphragm housing while two
port hook ups require a nipple and a plug to be installed in both lower and upper diaphragm housings. Use thread sealant on the
threads of the nipples and plugs to prevent leaks.
VALVE SEAT
The valve seat must be installed in the wastegate before mounting it onto the exhaust manifold. Failure to install the valve seat will
result in very limited boost produced by the turbocharger as the exhaust gases flow between the void where the valve seat normally sits
and the valve instead of flowing through the turbine.
