Had an e-mail from Forge this morning confirming the release of their DV valve - two different models, one for standard 2.0L FSI and the other for S3/ED30/Cupra.. See link

Anyone planning on fitting one, particularly anyone whos remapped? Where would be the best place to get it fitted, as I don't fancy doing it myself!! :smiley:

Look's a bit of a lash IMHO. I'd wait a see the Bailey version.

Bailey Motorsport are working on their own version, which I've been told still maintains the electronic element of the valve.

oh right, thanks for the info, think I'll sit back on this one for a few months and see what develops.

Whats a DV valve? Its not one of things that makes your car sound like a chav-chariot is it?

Dump Valves are fitted to the engines of turbo chargged cars and sit between the turbo outlet and the throttle body. When transitioning from a boosted state to a closed throttle state (as in between shifts), due to inertia, the turbo continues to pressurize air, but the closed throttle prevents the compressed air from entering the engine. In this case the pressure exceeds the preset spring pressure in the dump valve and the excess pressure is bled off to atmosphere.
Even with a dump valve the compressed air acts as a brake on the turbo (slowing it down), because the pressure on the backside of the turbo is at a higher pressure than on the front side (and the air actually wants to flow through the turbo backwards).
The Chav type are atmospheric type, and the woosh you hear is the gases venting to atmosphere., the recirculating type fitted to VAG cars, doesn’t obviously make this noise

thats ok then :smiley:

Chav-Chariot ...... :grin: Like it

My name is engraved on one of the first batch of ten in the UK - America has already had over 250. Should be installed next week.
The OEM VW Diverter Valve is a known weak link in the chain and especially on a remapped 2.0T FSI. I know people who have gone through three and VW's latest revison is already up to C.
Rather than explain at great length here, can I please be forgiven for posting a link to my thread on Tyresmoke where there is lots of info. You can then discuss it further here on GolfGTI.

It's a long thread but worth reading through to where Forge's very detailed info is posted.
:cool:

Limited supply of the new Forge DV at Awesome 0161 776 0777. Speak nicely to Sarah and say Robin sent you. £131.58+vat.
I'm booked in for installation next week, also with some pipework mods. It seems that most of you UK guys don't do much modding.

It's ridiculous how people are so quick to say thats "chavy" and whatnot. :sick:

....Well, we are all different but I too fail to see how a DV is chavvy - It's the spacer (a different component) that makes that phwoooosheee sound that many find chavvy. I think I would just find the sound irritating after a while. DV stands for Diverter Valve, not Dump Valve. Our Mk5 GTI engines have recirculating valves.
A heck of a lot of development has gone into the Forge DV and it's been thoroughly tested from the cold of Finland to the heat of Bahrain, and on some very highly modified 2.0T FSI engined cars.

Please let us know how you find the valve when you get it installed RedRobin, I'm very interested!

....Will do, Russ :smiley:.
The only 'problem' is that I'm installing SAMCO Turbo Hoses plus Neuspeed Turbo Hi-Flow Discharge and Intercooler Pipe, all in the same session as they all fit together and they open up the discharge 'line'. The Neuspeed components might make a difference to performance. I'll see if it's practical to take the car for a short run after just the Forge DV is fitted. I'm running switched to stock ECU at the moment.
I'm not expecting a significant performance gain from the Forge DV but reports across the pond in the US of A are suggesting that boost response is improved. I posted some lengthy info from Forge on the Tyresmoke thread but that site is currently very flakey so I can't get to it for you right now. The main thing is that it's far more robust than the VW version.
