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
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 (See diagram below).
• 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.
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 1 turn
or 2 Nm (0.73 ft/lbs) with an allen key. Be sure not to over tighten the screw as this will cause damage to the V-Band clamp and
deform the bore of the BOV.
• 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
• 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)
