GFB DVX Diverter Valve: The Real Deal for Boost Lovers

If you're looking to step up your game, the GFB DVX is where it's at. This isn’t just any diverter valve; it’s a serious upgrade from the popular DV+ model. What sets the DVX apart? For starters, it features dual venting outlets and a unique Venting Bias Adjustment System. This means you not only get better boost holding and throttle response, but you can also tweak the sound of your blow-off to your liking. Want it to be a subtle whisper or a loud whoosh? You got it!

Why Go for the DVX?

• Performance Focused: Unlike those BOV spacers that just make noise, the DVX actually enhances performance. It modifies how the valve operates to give you the same benefits as the DV+.
• ECU Control: Keeping that ECU control means quicker response times. It’s all about getting the best performance out of your engine.
• Sound Control: With the Venting Bias Adjustment, you can easily change how your valve sounds. Just slide the lever and you're good to go!
• Built to Last: This thing is tough. It’s designed to handle the rigors of both stock and modified setups without breaking a sweat.

One of the biggest headaches with factory diverter valves is their tendency to leak boost and wear out over time. The DV+ design tackles that issue head-on with a pilot actuation method that keeps everything tight and responsive. And the best part? You don’t have to toss your entire factory setup in the bin. The DVX keeps what works and improves what doesn’t.

What’s It Fit?

The T9654 is a direct factory replacement for the pneumatic diaphragm type bypass valves used in a bunch of popular models like Ford, Volvo, and Porsche. Here’s a quick list:

• Ford Focus ST (2013-2015)
• Porsche 911 GT2 RS (2011)
• Porsche 911 Turbo (2007-2009)
• Volvo C30 T5 (2008-2012)
• Volvo C70 T5 (2006-2009)
• Volvo S40 T5 (2004-2009)
• Volvo V50 T5 (2005-2009)

Why Not Just a Spacer?

Sure, there are loads of BOV spacers out there that make a racket, but they don’t fix the underlying issues with factory diverter valves. They just redirect air without addressing the flow capacity problem. With the DVX, you get a solid upgrade that actually improves performance.

ECU vs. Vacuum Control

Some BOV kits ditch the ECU control for pure vacuum control. While that works for a lot of setups, you’re missing out on the quicker response times that ECU control provides. The DVX keeps that fast ECU interaction, making it a smarter choice.

What’s Special About the Venting Bias System?

GFB's patented Venting Bias Adjustment System is pretty cool. It uses an internal rotating sleeve that lets you adjust the opening of both the recirc and atmosphere ports. So, if you want to go from a 50/50 split to full atmosphere venting, you can do that on the fly. Plus, with a single large port for the atmosphere outlet, the sound is deeper and way more satisfying than what you’d get from a standard spacer.

The Bottom Line

The DVX isn’t just about making noise; it’s about real performance gains and a blow-off sound that you can actually control. Whether you want to keep it low-key or turn heads, this valve has you covered.
