TurboXS BC-HPBC High Performance Manual Boost Controller

The TurboXS BC-HPBC High Performance Boost Controller is a precision-engineered manual boost controller designed to give turbocharged vehicle owners direct control over boost pressure. Using an adjustable ball-and-spring mechanism, this inline wastegate controller allows you to set and hold a target boost level with consistent, reliable results.

Unlike electronic boost controllers, the BC-HPBC delivers a straightforward, cost-effective solution for enthusiasts looking to raise boost pressure beyond factory wastegate settings. The ball-and-spring design bleeds off wastegate pressure in a controlled manner, allowing the turbocharger to spool to higher boost levels before the wastegate actuator opens.

Key Features:

• Adjustable ball-and-spring design for consistent boost pressure control
• Inline wastegate pressure line installation — no cutting of boost lines required
• Compact, lightweight construction for easy underhood fitment
• Compatible with both internal and external wastegate setups
• Simple adjustment mechanism allows quick boost level changes
• Durable construction suited for high-heat, high-pressure turbo applications

The TurboXS BC-HPBC is an ideal entry-level or backup boost control solution for any turbocharged platform, delivering the performance benefits of increased boost with minimal complexity and installation effort.
