Single Manual Boost Controller  & Switch Kit

MBC-1SS MBC-1SS Installed at PS Reservoir  Brkt MBC-1SS hose connection for factory turbo (note long hose 'T's into left IC pipe hose)

How they work:  Boost pressure goes into the MBC and is stopped by an internal ball, spring loaded against the thumb screw.  When Boost pressure exceeds the spring pressure, air bypasses the ball and sends pressure to the waste gate.  This slows the turbine, reducing compressor boost pressure.    Disclaimer:  These products can result in engine damage if not properly installed. The buyer accepts responsibility for correct installation and any damage resulting from installation.  The buyer must insure all other engine components are capable of the increased boost.   ALWAYS USE CAUTION WHEN ROAD TESTING UNTIL THE MBC IS PROPERLY SET. This boost controller spools up the turbo very quickly.  When boost is sourced from the intercooler pipe before the throttle body, it will regulate actual boost at the TB with little overshoot.    The  kit includes all items needed for installation 1. The simplest controller - lightweight aluminum body 2. Black Knurled Thumb Screw sets boost - notched face for reference - no tools required to set 3. Knurled Thumb Locknut - no tools required to lock 4. Easier adjustment - approx 2psi per 1/4turn means easier fine tuning and re-setting. 5. Sol/Sky mounting bracket, hoses, 'T' fitting, plugs & ties are included **INSTALL PDF** MBC-1SS  Price $59.95
