What kind of sound can I expect from the DVX blow-off valve?

The DVX features a patented venting bias adjustment system. You can infinitely adjust the valve's sound from completely recirculating and silent to a full atmospheric vent, which produces a noticeable sound. The adjustment is made simply by moving a lever.

This particular DVX model (T9654) is designed for specific applications including the Ford Focus ST (2013-2018), certain Porsche 911 models (2007-2009, 2011), and various Volvo models such as the C30, C70, S40, and V50. It is also compatible with Borg-Warner EFR turbos.

Product Details

You're getting the Go Fast Bits DVX Blow-Off Valve, a well-built unit designed to replace your factory diverter valve. This part is specifically engineered for a range of vehicles, including the Ford Focus ST, certain Volvo models like the C30 and S40, and even some Porsche 911s, as well as Borg-Warner EFR turbos. It's designed to help your turbocharger maintain boost pressure more effectively between gear shifts and improve throttle response.

What sets this DVX apart is its patented venting bias adjustment system. This unique feature lets you dial in the sound of your blow-off valve, allowing you to choose anywhere from a completely recirculating, silent operation to a full atmospheric vent that makes a noticeable sound. You can easily change this bias by simply moving the adjustment lever, giving you control over how your car sounds when you lift off the throttle. This improved boost holding capability means less boost is lost during shifts, keeping your turbo spooled up and ready for the next acceleration.

This DVX is a solid option if you're looking for the performance benefits of an upgraded diverter valve combined with the ability to customize the sound. It's a direct replacement for many applications, making installation straightforward for those familiar with turbo system work. Just be aware that this part is not CARB approved and cannot be shipped to California.
