This document is to be used as a guide for the installation of a TurboXS Standard Boost Controller to a turbo charged vehicle.  It is recommended that the installation of the product be carried out by a qualified mechanic.   

The TurboXS Standard Boost Controller is to be installed in series with the pressure line running from the positive pressure side of the turbo to the waste gate actuator system. 

Parts provided in  kit.

• Standard Boost Controller

• Mounting Bracket

• 6mm vacuum / pressure hose. 

• Zip Ties (hose clamps no longer included)

• 2mm Hex Key.                  
   

Installation Guide.  

1/ Locate the waste gate actuator.  Note, it is usually mounted on the turbo.   

2/  Identify the flexible pressure hose running from the positive pressure side of the turbo to the waste gate actuator.   

3/ Remove the pressure hose fitted to the waste gate actuator and insert it over the silver colored nipple of the boost controller.  Note the inlet direction arrow on the boost controller.  Use the pre-existing hose clamp to secure the hose onto the boost controller.   

4/  Take the extension hose and fit it onto the blue colored nipple.  Fit the other end to the waste gate actuator.  Use the supplied hose clamp to secure the hose onto the nipples.

5/  Mount the TurboXS Standard Boost Controller using the mounting bracket and screws located on the side of the boost controller to a secure part of the engine.   

Note : Installing the TurboXS Standard Boost Controller backwards will prevent the valve from performing properly.  Ensure the arrow stamped on the boost controller is in the same direction as the inlet supply pressure from the turbo.   

Caution : Failure to properly secure the Boost Controller nipples to the pressure hose can result in the disconnection of the waste gate actuator supply pressure.  If this occurs, the turbo boost pressure can rise to a dangerous level and could result in severe engine damage. 

Alternative Installation  

Cut the waste gate pressure hose and insert the supply pressure hose onto the silver colored nipple of the boost controller.  Insert the waste gate supply hose onto the blue colored nipple.  Secure the hoses with hose clamps.   

Adjusting the Boost Controller  

The boost pressure is ad j usted via the ad j usting screw located internally on the top of the TurboXS Standard Boost Controller.  The vehicle's boost pressure can be increased by winding the ad j usting screw in the counter-clockwise direction.  Once the boost pressure has been increased, winding the ad j usting screw in the clockwise direction will decrease the boost pressure.   

Note : The vehicle will require a calibrated boost gauge to be fitted in order that the turbo boost pressure can be monitored while ad j ustment is carried out.   

1/  With the ad j usting screw initially fully closed (ie : unable to be wound any further in the clockwise direction), wind the ad j usting screw three (3) turns in the counter-clockwise direction.  This will reduce the vehicle's turbo lag and increase the boost pressure by approximately one (1) to two (2) psi.   

2/  Once a one (1) psi increase in boost has been registered, each single complete turn of the ad j usting screw in the counter-clockwise direction will result in a one (1) psi increase of the boost pressure.   

3/  The boost pressure can be decreased by winding the ad j usting screw in the clockwise direction.  

Caution : No internal engine components can be warranted at greater than original equipment specifications.  This product is for racing use only.  Not applicable nor intended for use on emission controlled vehicles.
