hello fellas ive just done the n249 bypass and when i release off the trottle i get the chatter and not a clean pssst if you know what i mean i have got the forge 007p
-
Have the fitted the 1 way valve right way round?
-
mine done the exact same thing, I was told unless it sounds as bad as this......

then its nothing to worry about :cool:
-
Mine sounded exactly like this until I replaced my broken standard dv.

omg it does sound like this!!!!
what is the damage im doing to my turbo??
-
Well the sound is the air going back thru the turbo and stalling it. The research I did suggested this could brake the turbo over time.
* what DV you got?
* what spring?
* do you have it reversed?
* if you got the 007p does it have the upgraded piston?
-
The tone of my dv changed after bypass more chatter/flutter sound but nothing like that video lol

I've got the 007p with yellow spring and its the right way round
And how do I know if I've got the updated piston??
-
the old one has a dent in the bottom where as the new one is flat and the new one has a rubber seal onit
-
Does the spring go 1 way or are you on about the actual dv?

Thats the revised piston
-
thats the one
-
i have the old 1 then :( how much for the new one??
and where from :) ??
-
Ring forge and ask to buy a service kit. Tell them why they might send it for free like they did for ,e :)
-
blimey cheers buddy :)

Your welcome, keep us updated

this many posts and nobody has stated the bleeding obvious?
if it didn't chatter before you did the n249 bypass, and it does chatter now, it's really very simple.
You've done something wrong chap, and plumbed it in incorrectly.
it's that simple, no ifs or buts, if it sounded right before, and it now doesn't, you've done it wrong.

haha eh duh :P
for as bad as it is turbo flutter does sound awesome personally lol
-
ive double checked and done it twice now, the reason i did the n249 delete is because i had a boost leak from turbo to thottle body, many people suggested doing this to get rid/replace certain vacuum lines now the leak is still there which only possible thing i can thing of is the 007p and with lads saying there was a cock up with the piston maybe it might be the 007p
and nino i ended up getting it for free too :D
-
Sweet, make sure you clean out the old grease and change all the rubber rings. Also, do you have your DV plumbed in to the same line that shares the FPR? if so move it, try and plumb the DV so as a direct line as possible I.E .....
DV -------------> inlet manifold.
Or
DV -------------> one way valve -------> inlet manifold.
Not
DV -------------> FPR -----> boost gauge -------> inlet manifold.
Hope that makes sence, mine was 100% plumbed correctly but was a lot worse than it is now, but I originally plumbed it like step 3 now its ether step one or step 2 and it now does not flutter but at the same time it's not the pssssst it used to be, had it looked at and it's fine :)
-
hmmmmmmmmmm i t pieced my inlet mani---- DV-- to a boost gauge............ is this not reccomended then?
-
Best not to limited the DV line tbh
-
Where else can i take boost gauge feed from then? My dv goes to inlet mani pipe the one underneath to the right
-
Boost gauge SHOULD T into the dv line. It's either that or the fpr, and the fpr is not the place for it.
I still stand by my original comment. Plumbed up wrongly somehow.
-
I got my boost gauge plumbed into the the FPR and my DV is plumbed in on a different line. Persona,y when I did my install I followed the guide on this website that showed the boost should be plumped into the FPR but when I plumbed the DV into the FPR line with the boost I had a tiny flutter, when I moved the DV to a line that does not have lots onit my flutter stopped.
Now with pawns saying that I'm confused lol :undecided:
-
just take the boost gauge off to test it works :whistle:
-
I followed the guide on here too........ inlet mani to dv then T pieced a boost gauge feed
-
Rather than bypass it - id get some resistors and remove it
-
ok so to prawny theory to the test here a pic of what ive done
ok pipe going from the one way valve goes directly to the manifold...with a T piece to the 007p
the the pipe comming from the n112 goes to the thin metal pipe which i believe is for the Secondry air intake
and my boost guage is run off the throttle body from when i did the carbon canister delete

-
I'm saying take the one way valve out, it's probably stopping the DV opening :wink:
-
So remove the one bay valve completely ??
-
does the end of the one way valve go to the DV?
-
it T pieces off to the dv yea.... i removed the one way valve completely and its still fluttering also had the new piston put in and ive treble checked that ive done the mod right lol
-
Simple question then:
Is there a pipe, currently, that runs from your inlet manifold, straight to the top of the DV?
NO T's, no valves, just a length of 3mm vac pipe, from the inlet nipple to the DV, nowhere else.
Do that now if not, as a test, to confirm the DV is working.
