- MOST COMPACT WASTEGATE RANGE ON THE MARKET BODY, VALVE, SEAT AND ALL MOUNTING HARDWARE IS CNC MACHINED FROM HIGH-TEMP STAINLESS STEEL ACTUATOR HOUSING CNC MACHINED FROM BILLET 6061-T6 ALUMINIUM NOMEX-REINFORCED SILICONE DIAPHRAGM
- INTERNAL SHROUD PROTECTS VALVE STEM FROM EXCESSIVE HEAT AND PREVENTS CARBON-RELATED STICKING V-BAND CLAMP MOUNTING SYSTEM Manufactured In Australia under ISO 9001
The Go Fast Bits GFB EX38 external wastegate is engineered to deliver reliable boost control in high-performance automotive setups. Crafted from investment cast 253MA chromium-nickel stainless steel, the body ensures durability under extreme exhaust temperatures and harsh environmental conditions. The wastegate features a one-piece stainless steel valve and a nomex-reinforced silicone diaphragm, providing exceptional resistance to heat and mechanical stress. Its compact design makes it one of the most versatile and space-efficient wastegates on the market, ideal for a wide range of high-boost applications.
Designed with a 38mm V-band inlet and outlet, the GFB EX38 is directly compatible with Tial MV-S flanges, simplifying installation and ensuring a secure, leak-free connection. The V-band clamp mounting system enhances ease of service and adjustments while maintaining a robust seal. The overall height of approximately 37 inches and overall height of roughly 9.65 inches make it suitable for tight engine bays. The actuator housing is CNC-machined from billet 6061-T6 aluminum, ensuring precision and strength. The wastegate is supplied with a 10 PSI outer spring, with additional springs available for different boost settings, allowing you to tune your boost pressure from as low as 5 PSI up to 22 PSI by combining springs.
Internal features include an internal shroud that protects the valve stem from excessive heat and prevents carbon-related sticking, contributing to consistent performance over time. The internal components, including the seat and mounting hardware, are CNC machined from high-temperature stainless steel, ensuring longevity and resistance to thermal cycling. Manufactured in Australia under ISO 9001 standards, the GFB EX38 offers top-tier quality and reliability for enthusiasts and professionals seeking precise boost management in their turbocharged systems. Whether used in street, track, or racing environments, this wastegate provides the performance, durability, and ease of installation necessary for high-boost applications.
