NOTES ON BOOST CONTROL HOOKUP
WARNING! Changing your connection method can cause a higher than expected increase in boost pressure. Turbosmart recommends
adjusting your boost controller back to its minimum setting and measuring the new minimum boost pressure achieved by the new setup
before increasing your boost again.
IMPORTANT! Refer to your boost controller instructions for most suitable connection method to an external wastegate.
Basic setup
If no boost controller is being used connect the boost pressure source to the “bottom” port as shown. Connect the wastegate “top” port
to the intake side of the turbo, between the air cleaner and the inlet on the front of the turbocharger. Otherwise connect a short piece of
the silicon hose and face the vent downwards to stop water or debris entering the top port.
Boost Tee setup
When using your Ultra-Gate38 in conjunction with a Turbosmart Boost Tee, fit the controller between the boost pressure source and
“bottom” port as shown. Ensure the arrow on the Boost Tee is pointing in the direction illustrated. Connect the Ultra-Gate38 “top” port to
the intake side of the turbo, between the air cleaner and the inlet on the front of the turbocharger. Otherwise connect a short piece of the
silicon hose and face the vent downwards to stop water or debris entering the top port.
Refer to the instructions supplied with your Boost Tee for further detail if necessary.
