DV Valve
« on: 30 July 2008, 11:06 »
Hi All,

As some of you may have read I have recently had the Stage 1 Revo fitted and I am very impressed. Jim at JKM has told me that the boost psi is slightly lower than he would like and will be affecting the BHP. He said this could be caused by slight damage to the DV valve and would need to check it to be sure. Unfortunately I would have had to wait a couple of hours to have them check it out and I needed to go. I now need to get the old one off to check it and may as well replace it with a new stock DV valve. Jim has also said that sometimes the psi can be down and nothing to do with the DV valve but the ECU sorts it out over a couple of weeks. He could not explain why just cleaver engineering/electronics on the cars these days.

Anyone else had this problem? To be honest it doesn't feel like its lacking any power and cant imagine what it will be like if I get some more! :evil:

Anyone know the part number for a stock DV valve? I think there about £30?

If you're taking it off anyway, might aswell upgrade to a Forge one that uses a piston instead of a crappy plastic diaphragm :grin:

hey mate, get the forge valve, its much stronger than the OE one. I was lacking boost, 8psi to be exact but i dont think youl be that bad  :laugh: i had split hoses on my dv. then my car wasnt boosting past 5krpm so re-flashed the ecu and put a new map on and everything is sorted.

did JKM  say how much boost you were loosing? probs wont be the dv as when they go or split you would defo know about it  :smiley:

....The stock DV is well known as a potentially weak link, especially on remapped GTI's. A friend has been through 3 stock DV's on his MY04 GTI. The Forge DV is very robust and also holds boost better I'm told. JKM fitted mine - It's tricky because of where it's located.

How easy is the fitting on an ED30 John Hurdy? Obviously located in an easier location, but just wondered whether it was a garage or DIY job?  :huh:

I had it fitted at Awesome and they put it on in 30 mins. You have to take off the engine cover to get the piping fitted, but it is miles easier than the standard GTI. I'd definitely fit my own next time. Forge even have a download on their site for fitting and tips :cool: - you just have to ignore where they want to fit it as it is for the standard GTI location.
