WG45 Hypergate 45mm Ext Wastegate 7 PSI Black

The WG45 Hypergate 45mm External Wastegate 7 PSI Black from Turbosmart USA is a precision boost control component engineered for turbocharged engine builders and performance tuners seeking reliable, adjustable boost management. Uncontrolled boost can damage engine components, and this wastegate effectively vents excess exhaust pressure to protect your engine. Its design is ideal for those who require precise control over their turbocharged applications.

The 45mm port size is suitable for mid-range turbo applications, providing the necessary flow capacity for aggressive tuning. The Hypergate design features a heavy-duty poppet valve and a finned diaphragm chamber, ensuring smooth and responsive boost control across the power band. The 7 PSI spring setting allows for nominal crack pressure, which can be adjusted using Turbosmart's optional spring kits, sold separately.

This wastegate is particularly beneficial for turbocharged four- and six-cylinder platforms common in both import and domestic vehicles. Its external mounting configuration allows for versatile installation on exhaust or custom tubular manifolds. The all-black finish resists oxidation and corrosion, making it a durable choice for both street and track applications.
