GFB Spares- 7psi (inner) spring to suit part number 7001

GFB Spares- 7psi (inner) spring to suit part number 7001

🔧 Product Description

The GFB‑7107 7psi Inner Spring is a genuine Go Fast Bits (GFB) spare spring designed for use in the EX50 50mm external wastegate (Part No. 7001). It serves as the inner spring inside the wastegate actuator and establishes a base opening pressure around 7 psi (≈0.48 bar) when installed on its own or combined with other springs for higher boost settings.

This spring is perfect for tuners and performance builders who want precise, predictable boost control and the ability to fine‑tune base wastegate pressure in a high‑flow external wastegate setup.

⚙️ Key Features

• Genuine GFB inner spring (Part No. 7107)
• Rated around 7 psi base pressure
• Designed specifically for the EX50 external wastegate (7001)
• Precision‑formed for consistent boost control and tuning repeatability
• Can be stacked with other EX50 springs (e.g., 9psi middle, 13psi outer) to achieve a range of boost pressures

🚗 Fitment

• GFB EX50 50 mm External Wastegate (Part No. 7001)
• Suitable for custom turbo manifold wastegate setups
• Intended for performance street or race use

🏁 Performance Benefits

• Helps set the wastegate opening pressure to ~7 psi
• Provides smooth and consistent wastegate response
• Ideal when lower base boost is desired or when building precise spring stacks
• Combined with other springs, allows tuning to higher pressures such as 9, 13, 16, 20, 22, or 29 psi

🔩 Specifications

• Part Number: 7107
• Spring Location: Inner spring inside EX50 wastegate actuator
• Approx. Rating: 7 psi (~0.48 bar)*
• Application: EX50 external wastegate pressure tuning
• Brand: Go Fast Bits (GFB)
• *Actual boost pressure can vary depending on turbo, manifold, and engine setup.

🛠️ Installation Notes

• Installed inside the wastegate actuator housing
• Can be used alone for a 7 psi base pressure, or ganged with other springs for higher pressures
• Always refer to GFB setup instructions for correct spring combinations and placement

🧠 Why This Spring Matters

The spring inside a wastegate controls at what pressure the valve begins to open. The inner spring is one of the first lines of control — using the correct rating ensures consistent and reliable boost behaviour, especially on tuned engines.
