Should I fit a g revision DV.

[JMP]

G fitted today. N75 duty cycle looks to be back to normal. Great, but now my dsg clutches are slipping during upchange 2->3 and 3->4. Bloody hell, maybe Ill just trade the car for a mk6 or Polo GTI. Rant óver and our

I put a fresh "D" about 2000 miles ago. The DV noises were nearly gone altogether it was so quiet.

On the track last week it started squeeling like a pig in 4th and 5th WOT. The DV let off noises gradually lot louder as well

It stopped squeeling on the road but the DV noises were much louder than when it was new. Its now been replaced with a "G" and feels spot on

Glad that G I sold you is working well

This is hilarious.

All the hype about splitting diverter valves and how important it is to upgrade and now everyone is going backwards surely.

Guess there will be lots of rev d popping up in parts for sale.

I may jump on this and go G but I need some hard evidence not "it felt better," to

I did mention in my first post on this thread that R-Tech have smoke tested the D valve and found that it can leak boost. They now recommend the use of the G valve over the D valve.

A reputable tuner posting their findings & opinion based on testing was sufficient enough evidence for me 

[donovan2123]

"it can" does this mean it does leak or it "could" leak just like the g "could split" and leak more boost ?

Sorry if it comes across rude but I'm just a little bit baffled as to why it has taken this long to come to this conclusion.
Hopefully you will see where I'm coming from as I'm not knocking anyone's work just find it all very interesting.

They should do a back to back 10 rev d and 10 rev g and then see which is more consistent in loosing boost

[GarethB]

Totally agree with what your saying, and don't find it rude at all.

It is odd how seemingly everyone jumped on the piston bandwagon, and now seem to be reverting back to the diaphragm valve. We need someone with a boost gauge to perform back to back tests to compare.

I'm happy with RTechs findings regarding the leaking D valve, and happy to accept that any rubber diaphragm valve will eventually split. My understanding is that boost is held better with the G valve, but it will have a shorter life than a D valve.

For £30, I'm happy to consider it to be a consumable part and will check and replace at each service (if required) 

[MC71]

^^^^ completely agree. It's a replaceable item and not an expensive one either. As I posted previously I had a G originally, went to a D, back to the G now, both in A1 condition so am staying with what VW put on my ED30 (or at least until it goes pop).

 

[E30Dom]

What kind of pressure can the G take? Don't wanna fit one for it to go pop... And are they less prone to failure on ed30 due to being away from heat?

My C  looked fine when I removed for a D, wish I hadn't jumped so quick on the D bandwagon...

Interested in spec on new version on 2012 TSI engines...

[rich83]

Im running a G version (diapragm) and no spits yet... running stage 1 map.

[Statller-Stevo]

There seems to be so much swapping and changing from G's to D's to G's again... would it not make sense to just buy the best quality part and fit it once 

edit: i just read the post regarding Forge ones failing 

....That's what I did by buying the Forge DV (first batch in ~2006) - No problems to date.

So where's this post about them failing, please? Statler's Steve isn't at all specific in his comment if that's what you are referring to.

I have major problems with the Forge DV's sticking slighty open at idle , this then lets unmetered air back through the intake which the AFM cannot compensate for.
It basically cause's irratic idle issues
All my big power cars don't have these fitted simply because of this. The supersize are even worse!!! 

I've lost count of the amount I've changed

(I do like their nice coolers though)

John was telling me stories today of you being marched to a cash point by the Poliza on the way back from the ring one time, made me laugh mate
I'll have to try and get over there with you lot this year

Well JKM have just said its 06H145710C but that cant be right as that was the old green rubber one.
