GFB Spares- 13psi (outer) spring to suit part number 7001

GFB Spares- 13psi (outer) spring to suit part number 7001

🔧 Product Description

The GFB‑7113 13 psi Outer Spring is a genuine spare component from Go Fast Bits (GFB) designed specifically for the EX50 50 mm external wastegate (Part No. 7001). It acts as the outer spring in GFB’s modular spring system and is typically supplied as the default spring in the EX50 wastegate.

This spring establishes an approximate 13 psi base opening pressure for the wastegate and can be left alone for a 13 psi base setting or combined with other EX50 springs (7 psi inner, 9 psi middle) to achieve higher boost levels.

⚙️ Key Features

• Part Number: 7113
• Spring Type: Outer spring
• Rated Pressure: ~13 psi (~0.9 bar) base setting
• Genuine GFB performance tuning component for wastegates
• Precision‑manufactured for consistent boost control and actuator response
• Suits GFB EX50 external wastegate (7001) systems (50 mm series)

🚗 Fitment

• Suits GFB EX50 External Wastegate (Part No. 7001)
• Compatibility for custom turbo manifold setups and performance builds
• Acts as the outer spring in GFB’s modular spring stack system

🏁 Performance Benefits

• Sets the wastegate to open at ~13 psi when used on its own
• Offers stable and predictable boost control on high‑flow setups
• Supports consistent valve response in street or motorsport applications

🔩 Technical Specs

• Manufacturer: Go Fast Bits (GFB)
• Part Number: 7113
• Type: Wastegate outer spring
• Approx. Rating: 13 psi (~0.9 bar)
• Application: GFB EX50 50 mm Wastegate actuator tuning
• Use Case: Base spring and common tuning starting point

🛠️ Installation Notes

• Installed inside the EX50 wastegate actuator under the cap
• Can be used alone for ~13 psi base boost
• Always follow GFB’s official assembly guidance for spring order and orientation

💡 Why This Spring Matters

The spring inside a wastegate determines when the valve opens as exhaust pressure rises. The outer spring in the EX50 system provides the highest of the basic single‑spring base boost pressures offered and is the starting point for many performance builds.

Proper spring selection is essential to prevent boost control issues, and using the genuine GFB 7113 13 psi spring ensures you retain predictable and reliable performance.
