A BOV Controller Solution for Turbo Diesels Controller Kit
The BOV controller is an electronic device that controls the pressure signal to the BOV. It works by detecting a negative voltage change in the throttle position. It then energises a solenoid to vent all of the air out of the BOV cap, causing a pressure differential between the piston of the BOV and the cap, which will vent pressure from the intake system.
Large diesel engines with larger turbochargers can experience compressor surge when coming off the throttle.
The deceleration of the engine can be a restriction on the outlet of the turbocharger, causing compressor surge. This can be disastrous on a turbo system that is producing high amounts of boost.
The BOV Solution for Turbo Diesels
The BOV controller can prevent this build-up of pressure, protecting the turbocharger. This can reduce the number of rebuilds on your turbocharger as well as improve acceleration between gears. Proving to be a great BOV solution for a turbo diesel.
Application
Ideal for diesel engines and petrol engines.
FUNCTIONS
Sensitivity
How sensitive the controller is to negative changes in throttle movement.
Duration
How long does the solenoid stays open to bleed out the air from the BOV (i.e how long the BOV is open for) The solenoid will reactivate when the BOV controller reads positive throttle movement to close the BOV and pressurize the intake system.
Enable
Keeps the solenoid energized. This can be used as a boost limiting function as the BOV will bleed air out lowering the boost levels entering the engine.
Disable
Disables the BOV controller and returns the intake system to its factory setting.
Included in the BOV Controller Kit:
- BOV Controller
- Specific Race Port BOV
- Wiring loom
- Solenoid and bracket
- Reinforced pressure tubing
- Hose clamps and mounting hardware
