ABOUT YOUR EM SERIES BOV
Turbosmart has developed a unique “plug and play” diverter valve (or bypass valve) upgrade for your vehicle that is currently equipped
with an electronic diverter valve. While we have developed this unit to be as simple as possible for you to install, we have not
compromised on performance. This unit will not leak under elevated boost pressures and will still provide you with rapid response
ensuring that all the OEM calibration strategies are not interfered with, providing you with maximum boost performance while the
advanced strategies of the OEM’s are retained.
The EM series BOV is available in two configurations, Dual Port and Plumb Back. The functionality of the BOV is still the same, there
is no performance difference between the two units, it is a personal preference if the user wishes to utilise a classic vent to atmosphere
sound or revert all bypass gasses back into the inlet tract of the turbocharger.
As the valve is completely controlled by the factory engine control unit, the factory diverter valve is almost silent, due to our
construction, it is possible that your EM series will be much more audible. By being able to hear the unit actuate, occasionally the
valve may be opening for a few seconds under the following events such as traction control, cruise control management, rapid
gearchanges and varying throttle position changes, these are all coded as part of the torque management software in the OEM engine
control unit, there is no adjustment available over these functions via our product. By hearing these events, it is not abnormal, it is
completely normal for the EM series BOV to be considered “very active” as it is protecting your turbocharger from surge events or
bypassing air for torque management purposes.
