GFB Wastegate Actuator

The GFB (Go Fast Bits) Wastegate Actuator is a high-performance internal wastegate actuator. It is designed to improve boost control on turbo systems that already have an internal wastegate. It replaces the factory actuator and gives tuners and enthusiasts a compact, adjustable way to control turbo boost pressure.

Key Features:

• Large effective diaphragm area: A Nomex-reinforced silicone diaphragm gives the actuator more control over the wastegate flap. Exhaust backpressure has a harder time overriding the flap position, which supports stable, repeatable boost control.
• Compact design: A longer stroke and shorter overall height than many rival actuators help it fit in tight spaces.
• Adjustable spring pre-load: Interchangeable springs and a turnbuckle-style pre-load adjustment let you set the base boost pressure for your setup.
• Performance benefits: Faster spool-up, less boost taper at high RPM, more stable boost control, and support for higher boost pressures.
• Bolt-on installation: Designed as a direct replacement for the factory internal wastegate actuator, with mounting hardware supplied for the specific application.

GFB engineers and manufactures its products in Australia, and the brand is well known in the turbo tuning and performance aftermarket. GFB recommends that a qualified technician install the actuator. Changing the boost pressure requires proper adjustment and ECU tuning to suit your engine and its supporting modifications.
