What is the DVX Series?

The GFB DVX range is designed specifically for vehicles where standard aftermarket blow-off valves like the GFB Respons or Deceptor Pro II cannot be physically fitted due to space constraints or unique turbo system configurations. Rather than offering a generic universal BOV with adapters, GFB engineers each DVX version specifically for its target application, ensuring the best possible fit, sealing, and performance. The Veloster Turbo's compact engine bay and unique turbo system layout make it a perfect candidate for the DVX approach.

Adjustable Venting:

The DVX features adjustable venting, allowing you to tune the valve between full vent-to-atmosphere (VTA) and full recirculation. Vent-to-atmosphere produces the characteristic BOV sound as pressurized air is released to the atmosphere on throttle lift. Recirculation routes the vented air back into the intake system, which is important for vehicles with mass airflow (MAF) sensors to prevent rich running conditions. The adjustable design allows you to find the right balance between sound and drivability for your specific setup and tune.

Eliminates Compressor Surge:

When the throttle is closed under boost (such as during gear changes), the turbocharger continues spinning and building pressure against the closed throttle plate. Without a blow-off valve, this pressure has nowhere to go, causing the compressor to surge - a condition where airflow reverses through the compressor wheel. Compressor surge causes a distinctive fluttering sound, reduces turbo response, and over time can damage the turbocharger's thrust bearings. The GFB DVX relieves this pressure instantly on throttle lift, protecting the turbocharger and enabling faster boost recovery.

Improved Turbo Response:

By venting boost pressure on throttle lift, the DVX allows the turbocharger to maintain higher RPM between gear changes compared to a factory BOV. The factory BOV is designed for reliability and emissions compliance rather than performance, and often vents more slowly than an aftermarket unit. The GFB DVX's faster, more complete venting keeps the turbo spinning faster, resulting in quicker boost recovery and improved throttle response when you get back on the power.

Why Go Fast Bits (GFB)?

Go Fast Bits is an Australian manufacturer of high-performance blow-off valves and boost control products, known for their engineering expertise and application-specific approach to product development. GFB's DVX series demonstrates their commitment to developing proper solutions for challenging applications rather than relying on universal adapters. Their products are trusted by turbo enthusiasts worldwide for their quality, reliability, and genuine performance improvements.

Perfect For:

• Hyundai Veloster Turbo owners seeking aftermarket BOV upgrade
• Veloster Turbo builds wanting improved turbo response and protection
• Enthusiasts wanting adjustable vent-to-atmosphere or recirculation capability
• Anyone seeking GFB quality in a Veloster-specific application

Perfect For: Hyundai Veloster Turbo owners seeking GFB DVX blow-off valve for improved turbo response, compressor surge elimination, and adjustable venting.

Pro Tip: If your Veloster Turbo has a MAF sensor (most do), start with the venting set to recirculation and gradually adjust toward atmosphere - too much VTA on a MAF-equipped car can cause rich running at idle after BOV events.

Application Specific: Designed for Veloster Turbo where standard BOVs won't fit. Adjustable venting. Direct replacement. Eliminates compressor surge. GFB quality.

Protect your Veloster Turbo with GFB DVX blow-off valve - application-specific fit, adjustable venting, eliminates surge, proven GFB performance.
