ABOUT THIS PRODUCT  
Thank you for purchasing your new Turbosmart Boost Tee. This new model now has some great new features. These include:  
•
The option of either a slow boost ramp rate for sensitive setups or fast depending on Boost Tee configuration. This is achieved with  
either the restricted nipple as well as ball and spring.  
•
•
A wider boost adjustment range for wastegates with low spring base pressures.  
A new mounting bracket to make it easier to mount.  
IMPORTANT NOTES ON YOUR BOOST CONTROLLER  
Use only silicone hose that is the correct size and pressure rating for your application when fitting your boost controller – other hoses  
will be affected by heat and will eventually crack or split which could cause excessive boost pressure and engine damage  
•
•
•
•
•
•
Ensure that all plumbing is secured with clamps or cable ties.  
Your boost controller should be mounted at least 100mm from any heat source  
A Turbosmart Fuel Cut Defender may need to be used in conjunction with your boost controller – refer to www.turbosmart.com.au  
The boost dial has a left handed thread, be sure not to over tighten as this will damage the boost controller.  
Please note that the one turn (click) of the boost controller dial does NOT correspond to 1 PSI change in boost pressure.  
RECOMMENDATIONS  
•
•
•
•
Turbosmart recommends that the Air Fuel ratio is checked once boost pressure is set  
Turbosmart recommends that boost pressure is set using a Dynamometer and not on the street  
Turbosmart recommends that an accurate boost gauge be permanently fitted to the vehicle  
Turbosmart recommends that your boost controller is fitted and adjusted by an appropriately qualified technician

HOW TO INSTALL YOUR BOOST CONTROLLER  
TOOLS REQUIRED  
General mechanic tools  
1
Internal Wastegate Setup  
Allow the engine to cool down before installing your boost controller  
•
•
•
Locate the pressure source port and the wastegate actuator port on the turbocharger assembly (refer drawing 1)  
Remove the factory boost control solenoid if fitted from the boost pressure supply port while leaving the solenoid connected to the  
ECU  
•
•
•
•
•
Install your boost controller in the wastegate pressure line with the wastegate arrow pointing towards the wastegate actuator  
If your wastegate actuator has additional ports, these will need to be blocked  
Secure all silicone hose ends with hose clamps  
Mount your boost controller bracket onto the vehicle, then attach the boost controller onto the bracket with the supplied screws  
Make sure the boost dial is turned completely anti-clockwise before adjusting.

Locate the bottom port on the external wastegate and the pressure source port (refer Drawing 2)  
Install the Boost Tee in the wastegate pressure line with the wastegate arrow pointing towards the bottom port on the wastegate  
Secure all silicone hose ends with hose clamps  
Mount your boost controller bracket onto the vehicle, then attach the boost controller onto the bracket with the supplied screws  
Make sure the boost dial is turned completely anti-clockwise before adjusting.

Parallel Twin Turbo Setup  
Allow the engine to cool down before installing your boost controller  
•
•
•
•
Locate the wastegate actuator ports on both turbochargers and a pressure source port (refer Drawing 3)  
Remove the factory boost control solenoid if fitted from the boost pressure supply line  
Install your boost controller in the wastegate pressure line with the wastegate arrow pointing towards the wastegate actuators. • Be  
sure to keep the hoses joining the wastegate actuators at equal lengths  
•
•
•
Secure all silicone hose ends with hose clamps  
Mount your boost controller bracket onto the vehicle, then attach the boost controller onto the bracket with the supplied screws  
Make sure the boost dial is turned completely anti-clockwise before adjusting.

SETTING BOOST PRESSURE

Boost Spiking

Important notes on Boost Pressure  
Adjustment  
If boost spiking occurs and is undesirable for your application,  
the gate system can be removed to give you a less aggressive  
boost curve. This modification is only required in a minimal  
number of applications.  
•
Adjustment to your boost controller is made by rotating  
the Boost Dial. Please note that the one turn (click) of  
the boost controller dial does NOT correspond to 1  
PSI change in boost pressure.  
Bo
•
•
Rotate in a clockwise direction to increase boost and the  
reverse direction to decrease boost  
Before making any adjustment, the Boost Dial will need  
to be fully closed (anti-clockwise)  
Srtdep 1: Apply full load to the engine in a high gear (at least  
th  
3
or 4 gear) at full throttle and note the boost pressure  
Step 2: To increase boost rotate the Boost Dial clockwise  
(maximum of 1 complete revolution at a time)  
Step 3: Apply full load to the engine and note the boost  
pressure  
Step 4: Compare the actual boost pressure with the desired  
boost pressure. If the actual pressure is below the  
desired pressure, return to step 2. If the actual is  
above the desired boost then decrease by rotating  
the Boost Dial anti-clockwise and return to step 3.

Important notes on Gate system removal  
The gate system can be removed by the following steps.  
Perform this modification on a clean bench so that the ball and  
spring are not lost

•
Allow the engine to cool down before removing the Boost  
Tee from your vehicle  
Identify the input nipple with the restrictor at the end.  
Loosen the input nipple and remove the ball and spring.  
Check that the internal air passages are clear and free  
from debris  
Re-install the boost controller by following the instructions  
for your setup  
You will need to re-adjust your boost settings after the  
removal of the gate.

TROUBLE SHOOTING  
The following points should be checked if you find that your engine is developing excessive boost, the boost pressure is fluctuating, or  
the desired boost level cannot be achieved. Please note, the following checks will cure 99% of problems experienced when fitting a  
Turbosmart boost controller.  
•
•
•
•
Check that the boost controller is installed so that the arrow points toward the wastegate actuator  
Check the joining hoses for splits, cracks or loose connection and are the correct size for the application  
Check to see if the boost controller is blocked or contaminated with dirt or debris  
Ensure that there is nothing but the boost controller in the hose between the pressure source and the wastegate actuator, ie tee  
pieces for boost gauge or to factory boost solenoid.  
•
•
Pressure test the wastegate actuator for leakage, the diaphragm or housing may be cracked or split  
Check that the wastegate is operating correctly
