GARRETT 908828-0003 External Wastegate GVW-45 1 Bar (14.5 PSI) Black

Description GARRETT 908828-0003 External Wastegate GVW-45 1 Bar (14.5 PSI) Black

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. Delivered with a black anodized aluminum actuator cover, this wastegate comes complete with springs, fittings, flanges, and V-band connections.
