Garrett 908828-0003 External Wastegate GVW-45 1 Bar, Black

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 908828-0003 GVW-45 external wastegate in black is designed to regulate turbocharger shaft speed by redirecting exhaust gases around the turbine stage.

With a CFD-optimized design, it ensures maximum flow capacity and precise boost control.

Advanced thermal optimization improves diaphragm durability, while the robust cap construction enables quick spring replacement and simplified servicing.

Liquid-cooled actuator ports reduce body temperature by up to 52%, making the GVW-45 highly reliable under extreme motorsport conditions.
