GFB DV+ Diverter Valve - Renault Clio 4 RS / Megane 4 GT / Megane 4 RS

Why Risk Losing Your Renault Sport Performance? Discover the GFB DV+ Diverter Valve

As a specialist in performance vehicle customization and maintenance, Optimiz Access offers you a key component to ensure the efficiency and longevity of your engine: the GFB DV+ Dump Valve. Designed by Go Fast Bits (GFB), an Australian leader, this recirculating diverter valve is THE solution to the weaknesses of the factory valves equipped on your Renault Clio 4 RS, Megane 4 GT, or Megane 4 RS.

The Risk of the Stock Valve: What You Lose Without the GFB DV+

Did you know that the stock dump valve on your Renault Sport turbo is a potential source of power loss?

• Boost Leak (Loss of Pressure): The stock plastic diaphragm is vulnerable to heat and high boost pressure, leading to degradation or perforation. Without perfect sealing, you lose the crucial boost pressure, especially during heavy use or on the track.
• Lack of Responsiveness: The stock system is often slow to react. The result? Increased turbo lag between gear shifts, causing you to lose precious tenths in acceleration and recovery.
• Turbo Wear: In case of leaks or slow reaction, the turbo is subjected to stress (backpressure) that can reduce its lifespan. Failing to upgrade this part means risking damage to your Renault Sport turbo.

The GFB DV+ Solution: Reliability, Response, and Confidence for Your Renault Engine

The GFB DV+ is an upgrade kit that utilizes the original electronic solenoid, ensuring no ECU errors and a simple Plug & Play installation. You only replace the weak mechanical parts.

Reinforced Components for High Performance

Unlike the stock part, the DV+ includes:

• A body machined from CNC Aluminum (high strength, quality).
• A durable Brass Piston, replacing the plastic diaphragm.
• An exclusive pilot-actuated valve mechanism that ensures unmatched boost holding, even with an engine tune or remapping.

Faster Acceleration and Reduced Turbo Lag

Thanks to its optimized system, the DV+ offers 10% faster opening and 50% faster closing than the stock valve. What does this mean in practice? Near-instantaneous boost recovery, reduced turbo lag, and a better feeling of power delivery when exiting a corner or shifting gears. This is the most frequently cited improvement by enthusiasts of the Clio 4 RS and Megane 4 RS!

Frequently Asked Questions (FAQ): Your Investment in the GFB DV+

Does the GFB DV+ make a "Pschitt" Sound?

No. The GFB DV+ is an internal recirculating valve. It maintains the original operation and does not vent air to the atmosphere, preserving the engine's behavior and stock sound. If you are looking for the "pschitt" sound, you can check our complementary products (Spacers) available at the bottom of the page.

Do I Need Additional Modifications?

No, installation is Plug & Play. It replaces the old diaphragm and piston directly, without modifying the wiring harness or the ECU map. It is the first recommended reliability upgrade before any performance preparation.
