------------------------------------------------------------------------------------------------------------------------
IMPORTANT NOTES ON YOUR BOV
• Use only silicone hose that is the correct size and pressure/vacuum rating for your application when fitting your BOV
• Ensure that all plumbing is secured with suitable clamps or the correct fittings are used
• Your BOV should be mounted at least 100mm from any high heat source or adequately shielded
• This product might not work successfully on MAF/Airflow metered cars, please consult your local performance shop for more
information
• The Dual Port is supplied with an additional trumpet for full atmospheric mode. The plumb back fitting can be unscrewed from the
body and replaced with the trumpet if desired. Alternatively, either port can be blanked off with the supplied blank to change the
modes.
RECOMMENDATIONS
• Turbosmart recommends that your BOV is fitted and adjusted by an appropriately qualified technician

HOW TO INSTALL YOUR BOV
• Allow the engine to cool down before installing your BOV
• Identify a suitable location along the intercooler/intake piping for the BOV – this will need to be between the outlet of the turbo and
the throttle body ideally between the throttle body and the intercooler
• Remove the BOV from the weld on adapter by removing the V-Band clamp. The V-band clamp is removed by opening the screw
until it has reached the end stop, then pushing the head of the screw in a “syringe” like motion and lifting the BOV off the weld
flange. This flange can also be used as a 38mm hose adapter and can be secured with a hose clamp onto a piece of silicone hose
Step 1: Step 2:
Step 3
• Weld the adapter onto the intake pipe in your ideal position, then allow the adapter to cool down
• Put the V-Band clamp over the adapter before re-installing the O-Ring seal and the BOV
• Open the V-Band clamp and place in position. Tighten the V-Band clamp screw until it is finger tight then turn an additional 2.5
turns or 4 Nm (3 ft/lbs) with an allen key. Be sure not to over tighten the screw as this will cause damage to the V-Band clamp
• Identify a standalone vacuum / pressure source from a port after the throttle body and connect with correctly sized hose to the
vacuum/boost port on the cap of the BOV. Ensure this line is as short as possible
• Connect the plumb back fitting with the appropriate sized hose to a fitting between the turbocharger compressor inlet and your air
filter
• Secure all silicone hose ends with correct clamps
• Start the engine and check for air leaks in the system
Adjusting your BOV
• Adjustment to the BOV is made by rotating the cap, to increase spring tension rotate in the direction of hard, marked on the top of
the cap
• Rotate the cap in the direction of soft to decrease the spring tension – CAUTION Do not rotate the cap beyond the red indicator
groove
• Start with the BOV cap at the maximum soft position (The red indicator should be slightly covered by the edge of the cap)
• With the engine at idle the exhaust port should be closed off by the piston – the piston should be hard against the seat and not
floating or moving
• Free rev the engine and back off quickly, the engine should return to normal idle speed – if the engine drops below idle or stalls
increase the spring tension by one turn
• Repeat this process until the engine free revs and returns to normal idle speed
• Test drive the car and ensure that when decelerating or changing gears that the engine minimal backfiring and no stalling. If
backfiring is excessive or stalling is noticed then check all connections made during the installation, otherwise increase the spring
tension
