Garrett 908828-0001 External Wastegate GVW-45 1 Bar, Red

Garrett GVW-45 external wastegate — regulates turbocharger shaft speed by venting exhaust gas around the turbine stage, with CFD-optimised flow and precise boost control.

The GARRETT 908828-0001 GVW-45 external wastegate in red is engineered to regulate turbocharger shaft speed by venting exhaust gases around the turbine stage.

Its CFD-optimized design ensures maximum flow and accurate boost control, while advanced thermal optimization increases diaphragm durability.

The cap construction allows for easy spring changes and simplified servicing of the GVW series.

With liquid-cooled actuator ports capable of reducing body temperature by up to 52%, the GVW-45 is highly suitable for extreme motorsport applications.
