Title: forge split r fitted in recirc mode but getting turbo flutter from air filter
Post by: GTIcheeseman on 13 June 2012, 19:03
Right when I bought my car it had a dv26 which I replaced with a forge recirc but now I want a dv again so I got a dv36 but it don't seem to be right I'm getting turbo flutter coming back from my air filter, I have fitted the dv to the to intercooler pipe would it make any difference where it's placed? My old one was on a t price on the throttle pipe. Any help would be good also the dv36 does work fully

K
Also I don't want anyone saying buy a forge

Well I got a split r cheap to try if that worked and it's still fluttering , I think it's set to recirc mode but not to sure the top bit is twisted where it doesn't line up to any holes if that makes sense so still need help I'm gonna buy a service kit and spring kit and have a chop and change but it's still fluttering!!!! Help asap

Also tried adjusting the actuator but the end bolt is seized on the thread so it just turns the whole shaft

DV suck i had one.  :grin: my set up is the same with 007. You dont know what spring is in the DV for your map. Trust me ,my DV is on a shelf in shed. Have you got standard airbox ?

in my opinion that induction kit looks poop and your still sucking warm air from the engine bay

Post by: topher on 13 June 2012, 20:29
is it fluttering all the time? part throttle? or just when you should be getting the normal dump noise?

which intercooler pipe is the valve in and where have you attached the thin vac line to?
Title: Re: dump valve help
Post by: GTIcheeseman on 13 June 2012, 20:37
It's a fluttering like air going back onto the turbo. Mostly when ever boost comes on. The vac line goes to under the intake.mani I have an AGU if that helps

Post by: cullygti on 13 June 2012, 21:02
i had a dv on mine when i took it to be mapped and a similar induction kit to the one in the pic and my car was suffering from heat soak and a big loss in power due to the dv even tho i loved the sound f it changing to standard air box and recirc valve is much better and the difference in power is night and day i it wasnt for nick@r-tech putting a 007p on to show me the difference i probably wouldnt of believed it but when one of the best tuners around tell you they aint messing about  :smiley:

Yes I know that all but I'm not really bothering doing much more my golf apart from k03s and map and dv that's all I want . I don't want arecirc just a dv that works and any help would be good to solve my fluttering issue . I have just bought a cold side fitting kit as that is were it was when I bought it.

So just to re stat I don't want a recirc :D

The dump valve is dumping but not enough so it's back fluttering on the turbo . Could the spring be to strong?

Theres a reason everyone is telling you to get a forge recirc ...... Its not like theyve got shares and are trying to make money there trying to help !  :lipsrsealed:

Post by: GTIcheeseman on 14 June 2012, 16:10
Yes I know but I don't want one hence why I have said it! I want help with a dump valve not a forge recirc , I know my car works fine on one as it had one fitted when I bought it and worked lovely
Title: Re: dump valve help dv not dumping getting turbo flutter from air filter
Post by: golf-sib on 14 June 2012, 16:38
on my AGU, if a too stiff springs in the revs drop slowly with clutch disengaged due to turbo stalling. But I get no chatter noise, I also find it revs over 7200 rpm with a stiff spring in.

Yours works fine? Mine was running rich with a "dump Valve".(I may add it was on the engine when purchased  :grin:)
I have always been told if you have an air flow meter you shud NEVER run a dump valve.

If you want constructive advise then you should listen to what were saying.

If its not dumping enough then the spring is prob too weak maybe, is it making a noise under boost similar to a tyre with a loud puncture?? (sorry this is the best way I can describe it haha)

Sounds like the dump valve is letting air through it under boost to me.
Title: Re: dump valve help dv not dumping getting turbo flutter from air filter
Post by: GTIcheeseman on 14 June 2012, 16:47
Tbh the dump valve sounds like a duck quack lol but it still flutters through the filter. When I got it there was no issue with anything it boosted fine and worked perfect
Title: Re: dump valve help dv not dumping getting turbo flutter from air filter
Post by: DunnDeal12 on 14 June 2012, 17:12
people on here cant advise you on a DV because quite simply there crap on the 1.8T engine and cause problems.

007p & 008 FTW

Post by: JimBR on 14 June 2012, 21:19
I dont know why your so desperate for a DV...

My forge 007p and Jetex filter give a more than loud enough tshhh with none or the problems your having.
Title: Re: dump valve help dv not dumping getting turbo flutter from air filter
Post by: GTIcheeseman on 14 June 2012, 21:37
Right servicing it would be an idea , but what grease would you use?

I know what people are saying but I just wanna go back to how it was
Title: Re: dump valve help dv not dumping getting turbo flutter from air filter
Post by: GTIcheeseman on 14 June 2012, 21:46
Right where on the two pistons do I apply this grease? I have red grease at work or rubber lube grease or lithium grease any of these good?
Title: Re: dump valve help dv not dumping getting turbo flutter from air filter
Post by: golf-sib on 14 June 2012, 21:59
Use the red grease, lithium is a bit to thick and heavy. Basically with the forge DV it's:
1) open the DV up by undoing the top
2) slide the piston out
3) wipe clean piston and inside DV
4) you have 3 o-rings, two that sit inside the dv and act as a air seal between the outer casing and piston - renew if necessary
5) third seal is same as above - renew if necessary, this is located either on the top end of the casing or in the screw top
6) apply grease and reassemble

Not played around with a stock one for a while, it may be similar or it may be a solid unit.

Wazzieeeeee

Email forge and say you never got a yellow one in your kit, they will send you one free of charge as there customer service is brilliant.

Thats what I did as I only got one in my kit only, they where very helpful!

I brought mine from awesome and all i got was the 007p itself no springs service kit not even wrapped well it was just in a forge box with no packaging if i emailed forge would they send one out ?
Title: Re: dump valve help dv not dumping getting turbo flutter from air filter
Post by: rockmonkey69 on 15 June 2012, 17:42
Spring kit is sold separately from Forge, it does not come with the 007p

Try, see what they come back with, I have found there customer service to be exceptional, I doubt they will send out the service kit as they charge for these now.

If you generally never got the spring you desired they will typically send you one free of charge, just don't abuse there generosity.
Title: Re: dump valve help dv not dumping getting turbo flutter from air filter
Post by: Wazzzer on 15 June 2012, 17:51
I would have thought you should get at least one spring in there  :undecided:

Right I serviced it with red grease. Basically it does work but only really at boost at low poddle it gets turbo flutter I'm.gettin rather confused

You scanned for any codes?

Weak actuator, boost leak?

Engine code?
Title: Re: dump valve help dv not dumping getting turbo flutter from air filter
Post by: GTIcheeseman on 15 June 2012, 22:16
Saging that maybe it is the actuator as it is a bit weak, I mean it's the original turbo that's done 130k lol

I have an agu
Title: Re: dump valve help dv not dumping getting turbo flutter from air filter
Post by: golf-sib on 15 June 2012, 22:30
AGU, could be a few things, what revs is it happening, how is it holding power, or no power even when boost is in? Also is it drinking fuel?

It may well be the actuator, you running a remap?
Title: Re: dump valve help dv not dumping getting turbo flutter from air filter
Post by: GTIcheeseman on 16 June 2012, 08:10
About 2.5 - 3k . Power wise it feels very slightly down on power but not much and it isn't drinking much more than normal
Title: Re: dump valve help dv not dumping getting turbo flutter from air filter
Post by: golf-sib on 16 June 2012, 12:33
I'd say either actuator, possible a boost leak, some are very difficult to spot, I've had leaks that I never known about till the silicone split more apart, but since you got an agu most of the vacuum side can be replace with 8mm and 3mm silicone hosing which is cheap as chips.
Title: Re: dump valve help dv not dumping getting turbo flutter from air filter
Post by: GTIcheeseman on 16 June 2012, 15:25
Most of the pipes have been replaced... So I'm assuming it is probs the actuator
Title: Re: dump valve help dv not dumping getting turbo flutter from air filter
Post by: GTIcheeseman on 16 June 2012, 16:14
Could I adjust.my actuator to make it a bit stronger for the mean time?
Title: Re: dump valve help dv not dumping getting turbo flutter from air filter
Post by: golf-sib on 16 June 2012, 16:26
Give the actuator a go, pretty straight forward to do, even better if you have FMIC that goes round via passenger side this means you can easily work on the actuator with the bonnet up :smiley:
Title: Re: dump valve help dv not dumping getting turbo flutter from air filter
Post by: GTIcheeseman on 16 June 2012, 16:31
Got a rough how to?
Title: Re: dump valve help dv not dumping getting turbo flutter from air filter
Post by: Wazzzer on 16 June 2012, 16:41
I'd say actuator too. Be careful playing with it though, too much preload and you'll kill the engine

Ccarefully tweaked it like 1/4 turn max and it's still fluttering

Need an actuator :(
Title: Re: dump valve help dv not dumping getting turbo flutter from air filter
Post by: golf-sib on 19 June 2012, 21:29
Sure its not a boost leak? I remember when I modded my airbox to have a solid 2.5" cold intake pipe. At the end of the pipe I had a cone filter and removed the panel filter. What I ended up with was huge flutter and hardly and high end power. Turns out the box filter is designed in a manner where it make the air box air tight, because it wasn't air tight I was getting inconsistent readings on the MAF and couldn't work out wtf was going on and under high end it just felt rubbish. Drank fuel like it was in the desert too, 3mile trip cost me £10.

So it seems like a leak, but I'd still look over the system as well just encase its not just the actuator (TIP and vacuum hosing). Also get the forge actuator, a real good piece of kit to replace the OEM one.
