In the event that your car seems like it's dropping its punch during gear changes or under heavy velocity, swapping to an mk6 gti gfb dv+ will be probably the one best thing a person can do for your turbo setup. It's one of these rare parts that doesn't cost a fortune but actually solves the design flaw that's been nagging Vw owners for a long time.
Those who have invested enough time driving of a Mk6 GTI knows that while the 2. 0T TSI motor is a treasure, it's got several quirks. One of the most common issues is the particular factory diverter control device (DV). Whether a person have the older diaphragm style or maybe the newer piston design, they both possess their share associated with problems. The GFB DV+ (Go Quick Bits) isn't just a replacement; it's more of an "evolution" of the part that ought to have been there from the manufacturer.
Why the Stock Diverter Device Fails
To understand why the particular mk6 gti gfb dv+ is really well-known, you first have got to look at what VW gave us. The authentic "Revision G" regulators used a silicone diaphragm. As you can imagine, placing a thin piece of rubber close to a scorching warm turbocharger and requesting it to keep 15+ psi of boost is a recipe for devastation. Eventually, that silicone tears, you already know boost, and your vehicle feels like it's driving through dirt.
VW attempted to fix this with the "Revision D" valve, which swapped the plastic for a plastic material piston. While it doesn't "tear" such as the old 1, it has the own set of issues. Because it's a hard plastic piston, it doesn't usually provide an ideal seal. It's the "leaky" design simply by nature. If you're running a Stage 1 or Stage 2 tune, that will tiny leak becomes a much bigger problem. You're asking turbo charged to work harder in order to compensate for the air getting away past an average valve.
How the GFB DV+ Is proven to work
The "Plus" in the title is the key. Unlike some aftermarket valves that replace the whole electronic solenoid, the particular mk6 gti gfb dv+ really keeps the manufacturing plant solenoid. This can be a massive benefit since the car's ECU is incredibly fast at managing that solenoid. Automotive aftermarket mechanical valves may sometimes be slow compared to computer likes, resulting in weird surging or fault requirements.
The GFB kit replaces the particular weak plastic/rubber internals with a precision-machined metal piston and a heavy-duty housing. Yet the real miracle is the "pilot-actuated" operation. Instead associated with the solenoid straight pulling the piston open, the the solenoid controls the surroundings pressure that goes the piston.
What does that mean to suit your needs? It means the valve only starts as much as it requires to. It stays shut under boost much more efficiently than the share unit, and it closes considerably faster. This particular results in very much sharper throttle response and better increase recovery when you're rowing through the gears.
The Difference You'll Sense on the Street
If you're expecting a massive 20-horsepower gain just from installing this particular, I've got several bad news. It's not about peak power; it's about just how the car delivers that power .
The first thing most people discover after installing a good mk6 gti gfb dv+ is that the "lazy" feeling between shifts disappears. On the share valve, when a person lift from the throttle to shift plus then get back again on it, there's a split-second delay whilst the turbo creates pressure again. With the GFB unit, it holds just enough pressure in the system so that the boost is right there waiting with regard to you the moment a person floor it again.
It also smooths out the power delivery. Sometimes the stock valve may be a bit "on/off" in the behavior, leading to a jerky sensation whenever you're modulating the particular throttle. The GFB piece makes the car feel a lot more enhanced and responsive to your own right foot.
Installation: A Bit of a Limited Squeeze
I won't lie to you—installing the mk6 gti gfb dv+ on a Mk6 GTI can become a bit of a test associated with patience, mostly because of where VW decided to put the diverter valve. It's tucked away on the back of the turbocharger, that is situated between the engine and the firewall.
You're going to become working mostly by feel. Here are usually a few ideas to make it easier: * Cool Down: Don't try this right after a drive. You'll be reaching right alongside the exhaust manifold and the turbocharged housing. Give it at least two hours to cool-down. * The Right Equipment: You'll need a 5mm Allen key or the hex bit. The long extension using a "wobble" end will be your best friend right here. * Don't Drop the Bolts: Seriously. If you drop among the three bolts to the underworld of the motor bay, you're going to have a poor time. Use a magnetic socket in case you have a single. * Lube it Upward: The particular GFB kit comes with a little bit of bit of oil. Make sure you lubricate the metal piston before you glide it into the housing. It needs to move freely to work correctly.
It typically takes about forty five minutes to a hour if you're useful with a wrench. If it's your first time working upon the Mk6 platform, maybe budget 2 hours just so you don't really feel rushed.
Exactly why Not Just Obtain a Blow-Off Valve?
We've almost all heard that "pssh" sound from modified cars and believed it sounded awesome. However, the Mk6 GTI uses the Mass Air-flow (MAF) sensor. The engine has already assessed the air arriving in and determined how much energy to spray. If you utilize a Blow-Off Valve (BOV) to vent that air in to the atmosphere, the ELECTRONIC CONTROL UNIT gets confused because the air it measured is suddenly gone.
This usually leads to the particular car running rich for a 2nd, stumbling, or also stalling at stoplights. The mk6 gti gfb dv+ is a recirculating control device, meaning it will keep that air inside the system where it belongs. A person get all the particular performance benefits with no the annoying driveability issues or check out engine lights. In the event that you really would like more sound, an open intake may give you plenty of turbo noises while still maintaining the GFB control device doing its job correctly.
Durability and Reliability
One of the best reasons for this particular mod is that it's essentially a "set it and forget it" part. Mainly because it uses a brass piston plus a beefy spring, there isn't very much that can make a mistake. It doesn't possess a rubber diaphragm to perish, and it's built to manage higher boost amounts than a stock GTI will ever see.
Whether you're just daily driving or striking the periodic track day, understanding your diverter control device isn't leaking air flow provides a lot of peacefulness of mind. It's often recommended as a mandatory supporting mod for anybody getting a software melody, as the elevated boost pressures of a Stage 1+ map will find the weaknesses inside a stock valve very quickly.
The Final Judgement
Is the particular mk6 gti gfb dv+ worth the particular money? If you care about how your vehicle drives and you wish to ensure you're getting every pound of boost your own turbo is producing, then absolutely. It's one of these modifications that links the gap in between a "repair" and a "performance upgrade. "
It fixes a known weak point, increases throttle response, and handles extra increase like a champion. In the wonderful world of VW tuning, where things can get expensive and complicated very quickly, this is a straightforward, effective, and fairly affordable way to make your MK6 GTI seem like the car it had been always meant in order to be. If your own GTI is starting to feel the little tired or even inconsistent, give this particular a shot—it could just be the "refresh" your turbo system wants.
