Turbosmart Dual Stage Boost V2

The Turbosmart Dual Stage Boost V2 is a manual boost controller (boost control valve) for turbocharged engines. It gives you two separately adjustable boost levels, so you can switch between a low and a high setting while driving. It is a popular upgrade over factory boost controllers, and a straightforward way to raise boost and tune turbo response on boost-actuated wastegate setups.

Key Features:

• Dual-stage operation: toggle between high and low boost on the fly, and adjust both settings.
• Billet aluminium housing: made from high-grade billet aluminium for a robust, stable design.
• Bullet valve technology: built for fast boost response.
• Gate feature: Turbosmart's Gate feature is designed to reduce wastegate creep. Turbosmart says it can bring turbo response up to 800 rpm earlier in the rev range without raising maximum boost.
• Detent adjustment system: lets you tune boost pressure accurately and simply.
• Easy installation: made to be easy to fit, and works with boost-based internal wastegate actuators and external wastegates.
• Remote switch: works with a Rocket Launcher switch to change between boost levels.

Turbosmart says stable boost increases of 200% or more over spring pressure are common on internal wastegates, and around 100% on external wastegates. A manual boost controller cannot lower boost below the base wastegate spring pressure. This controller is not compatible with variable geometry turbochargers (VGT, VVT or VNT).

Turbosmart began making performance products in 1997 and designs and builds them in Sydney, Australia. The brand is known for quality and reliability. The Gated Boost Control Valve range suits mildly modified turbocharged engines and factory-turbo applications.
