Garrett's GVW-50 gives turbo enthusiasts the best possible way to control extreme boost levels and combat boost creep in any racing turbocharger. This 50mm wastegate efficiently vents exhaust gas around the turbine to regulate precise turbocharger shaft speeds while keeping backpressure to a minimum. The 50mm valve is ideal for high-RPM or large-displacement engines where boost creep is a concern.

The GVW-50 kit has been CFD tested and is proven to deliver maximum flow, thermal efficiency and superior durability. Made from high-temp stainless steel, it is rated for exhaust gas temperatures up to 1050°C.

The GVW-50 is no simple wastegate. Garrett engineers spent over a year on the design — a project meant to take a few months absorbed a whole team for a year. The result: the GVW family (GVW-40, GVW-45 and GVW-50) flows 5% more than any competitor and stays completely consistent at high temperatures, whether you're drag racing or running endurance.

Shipped set to 1 bar (14.5 psi), the GVW-50 is fully configurable anywhere from 0.2 bar (2.9 psi) to 1.7 bar (24.7 psi).
