IMPORTANT NOTES ON YOUR EXTERNAL WASTEGATE
-
Fitting your Ultra-gate38 may require fabrication or modification to your exhaust manifold. Turbosmart recommends that your
wastegate is fitted by an appropriately qualified technician.
- The Ultra-gate38 is designed for use with a turbocharger that does not have an internal wastegate.
- Consult your local specialist before setting your desired boost pressure, setting boost beyond your engines capability may result in
engine damage.
- DO NOT wrap the body of the wastegate with exhaust wrap
- DO NOT Mount the wastegate so that the top diaphragm housing is less than 100mm from a heat source
- Allow for adequate cool airflow around the top diaphragm housing
RECOMMENDATIONS
-
Turbosmart recommends that boost pressure is set using a Dynamometer and not on public roads.
- Turbosmart recommends that a boost gauge be permanently fitted to the vehicle.
- Turbosmart recommends that the engines Air/Fuel ratio is checked while setting the desired boost pressure, as any increase in
boost pressure can cause the engine to run “LEAN”, resulting in possible engine damage.

BASIC COMPONENTS OF YOUR ULTRA-GATE38 38MM EXTERNAL WASTEGATE
Use the diagram to help identify the “top” and “bottom” ports, and inlet/outlet ports of your wastegate.
- When pressure is applied to the “bottom” port of a wastegate, i.e. underneath the
wastegate diaphragm, it acts against the wastegate spring and the wastegate valve opens.
-
When pressure is applied to the “top” port of a wastegate, i.e. above the wastegate diaphragm, its acts with the wastegate
spring and helps to close the wastegate valve.
- The Inlet is connected to the exhaust manifold before the turbine housing of your
turbocharger. See recommendations following for Ultra-gate38 mounting position.
- Outlet returns exhaust gas back into the exhaust system after the turbocharger. (NOTE if mounted on a dedicated race car
the outlet can be vented directly to atmosphere towards the ground)
