How To Install Boost Controller In Your Car?

A boost controller is a device that controls the level of boost from intake manifold of a turbocharged engine. The device controls the boost by having an impact on the air pressure taken to pneumatic mechanical actuator. A boost controller is available in both manual and electronic. The manual one is sometimes part of computerized engine in a turbocharged car and provides easy fabrication.
Before installing manual boost controller, it is important to add a high flowing exhaust and an air intake or air filter. This gives the car ability to breath and at the same time allowing the turbo to spool easier. It is important to look for an aftermarket air filter or boost gauge because other types of boost gauges are not accurate. If you do not install an aftermarket boost gauge the car's engine might be at risk of over boosting.
The function of westegate actuator is to determine the levels of your stock boost. Boost controller interrupts the pressure line that is running to westegate actuator. Therefore, you can increase boost over stock levels.
How to install boost controller in your car

• Look for a westegate actuator to attach on the turbo.  This device has vacuum line port that connects boost source. The boost source can be either turbo's compressor housing or intake manifold or intercooler pipes.
• Install manual boost controller at the vacuum line. Some vacuum line have T fitting between the boost and westegate actuator, therefore they have separate vacuum lines running to boost control solenoid. It is good to remove the line that runs to the solenoid if you have T fitting.
• Drill a small hole on boost controller barb that connects westegate actuator. It is important to leave the hole open and do not switch Westgate barb and boost barb.
• Most boost controllers are almost 3 feet of vacuum line and therefore you can divide it into two pieces of any lengths. Use the first piece to connect boost controller barb and boost source. The other piece uses it to connect westegate controller barb and westegate vacuum port.
• Sliding the vacuum lines into the barbs can be difficult but you can use oil to lubricate the barbs.
• Use vacuum cups to block any open boost sources and use cable ties to protect vacuum line connections.

It is important to use premium fuel for your turbo car after installing boost controller. Test the car after installing manual boost controller. The boost is either increased or decreased when you turn the knob clockwise or anticlockwise.  Gently press the gas as you watch the boost gauge rising.  Your car has a maximum safe boost that depends on cars upgrades and features of fuel system.  Find out the maximum boost level your car can run.
