Specific Product Information
Relevant tech information
Features of VTA:
- Capable of handling upwards of 50psi.
- Direct-fit replacement with GFB’s TMS benefits
- Utilises pilot actuated operation, allowing for increased throttle response and better drivability.
- Replaces weak plastic components with metal components which have been found to solve boost leaks and improve boost holding.
- Progressively opens in response to boost pressure – only opening as much as is required.
- Vent to atmosphere capable.
Use cases:
- Applicable for vehicles fitted with a vacuum actuated diverter valve
- If an aftermarket turbo from another vehicle is used, please contact us to confirm fitment.
FAQ:
What’s the difference between the VTA and DV+?
o The main difference between the VTA and DV+ is only that the VTA is capable of venting to atmosphere whereas the DV+ cannot. They both have the same performance related benefits being better boost holding, solving boost leaks and increased throttle response.
Why does my piston have a blue seal instead of the silicon one that I’ve seen before?
o We’ve recently adopted more modern production methods and sustainable materials that have allowed us to evolve our piston seal technology. By changing to a blue VITON seal, we’ve been able to ensure that we’re still able to guarantee the same performance and durability at our high-quality standards. Performance without compromise.
Do any components in this kit need to be lubricated with engine oil?
o No! Unlike our DV+ kit, you will not need to lubricate the piston or plunger of your VTA. We pre lubricate the piston when installing the piston into the body of the VTA and there is enough blow by through your engine to help keep this piston lubricated. You will also, not need to lubricate the plunger.
I’m interested in your lifetime warranty policy, what does this include?
o We offer lifetime warranty on all of our products, so provided that there is a genuine manufacturing or assembly fault with your product – please send us some photos of what’s going on so that we’d be able to assist with either replacement parts or components. It’s also worth noting that we our lifetime warranty does not extend to those who have purchased our parts second hand.
What does the spring preload screw do for my VTA? Is it necessary to do?
o Adjusting the spring preload screw is an optional step that can be performing in an attempt to improve throttle response and reduce lag. The pressure balancing design of the VTA means that until the ECU decides to open the diverter, there is equal boost pressure on both sides of the piston, so it will stay shut under boost regardless of the spring setting or the boost pressure.
Self-troubleshooting steps:
How do I know that my VTA is working as intended?
o Uninstall the VTA from your vehicle and lay the body of the VTA on its back and press against the piston. You should be able to freely press against the piston without getting stuck. If you do find that there is some abnormal behaviour, please do not hesitate to contact us at [email protected]. Please be sure to include a video of your performing this test.
I’m finding that I’m losing boost whilst on throttle! Help!
o If you’re experiencing this, we highly recommend double checking to see if there is any damage to your vacuum hose going to the diverter valve. Please ensure that this hose is in good condition and is not damaged. This hose will NOT need to be replaced/repurposed when installing the VTA. It can simply be reused.
Next steps:
If you are still having trouble, then the next steps are to contact our Tech Support team. Videos, photos, and a clear description of the symptoms you are experiencing would give us a better understanding of what is going on and how to resolve this issue as quickly as possible. Remember, we can’t see your car or product, so our diagnosis is only as good as the information that you provide us.
