Control the boost from the driver’s seat. Ideal for the active enthusiast who wants boost adjustment on the run. Detent System makes adjusting a breeze. Gated System brings boost on faster. The Turbosmart Gated Boost Control Valve range is one of the best dollar-for-horsepower upgrades you can make to your turbocharged petrol or diesel engine vehicle. All Turbosmart Gated Boost Controllers feature our exclusive Gate feature, which minimizes wastegate creep and can improve turbo response by up to 800 rpm earlier in the rev range – this means you can increase the performance and response from your engine without even raising the maximum boost level. Stable increases in boost over wastegate spring pressure of 200%+ for internal and 100% for external wastegates are standard practices using our manual boost controllers. Manufactured from high-grade brass and billet aluminium and are renowned for their easy installation, robust design, and stability. Our detent adjustment system allows for accurate and simple tuning of boost pressure. The Turbosmart Gated Boost Control Valve range is ideal for mildly modified turbocharged engines and is perfect for increasing boost levels on factory turbo cars and engines.
