Vent exhaust gas around the turbine and precisely regulate turbocharger shaft speed on any racing turbocharger with Garrett's 40mm external wastegate kit, the GVW-40. Garrett spent a full year designing the GVW family (GVW-40, GVW-45 and GVW-50) to build what they considered the best wastegate available.
The GVW-40 has been CFD tested for maximum flow, thermal efficiency and durability. The valve body is cast from high-temp stainless steel and rated for exhaust temperatures up to 1050°C, and the design was crafted so the wastegate stays dead consistent no matter the temperature, year after year. It delivers the maximum flow possible — 5% more than any competitor — giving you the best performance from your turbocharger and the most efficient output from your engine.
When it ships, the GVW-40 is set to 1 bar (14.5 psi). With the included springs you can configure it from 0.2 bar (2.9 psi) to 1.7 bar (24.7 psi) base boost. Garrett recommends the GVW-40 for twin-scroll dual wastegate applications.
