I've been having a few probs recently that were boost related on my Golf and I think I've found the culprit...
It's had a really loud intake noise on boost and I've been seeing 24psi on some runs which I hadn't been seeing when I just got the ECU back from the the remap
I'd also been hearing what I can only describe as a fluttering noise and then sometimes the turbo stalling and losing power
My first thought was the turbo was shot but I decided to do a bit more thinking as there were no other symptoms to back this up
Since changing the N75s over I don't get the really loud turbo wind up and I'm seeing about 16psi but I can't do much else due to roads being either too busy or old bill floating about and I don't fancy 3 points as an early Xmas present lol
Does this sound right to anyone else that's had one go wrong?
I'm leaving everything alone now until I get a chance to go up to R-Tech and get the boys to give it a thorough going over :laugh:
-
Could it be the DV, as my mate got alot of flutter with a DV that went, just a thought?
Didn't know AGU's had n75 valves, where are they?

I no were basic but yes we have the N75 valve lol! its located on the turbo intake pipe!
i have also been getting strange boost readings as well wazzer, hitting 25psi in 2nd and 23psi in 3rd!

Imagine it must be alot of fun, but can the k03 keep up with it as I though over boost damages and wears the turbo out?
Also any idea of what the internals can take boost/torque wise?
-
we both run the k03s :wink:

:laugh: k03s
How much of a difference are the k03's as im debating between going ko3s or ko4-001 (direct bolt on, but havent found anyone with one to tell me if its any good)
-
For the money spent getting the K04 to full potential i dont think you will be happy, I'd say K03s IMO.

Didn't think so since it's been over a week :undecided:,i have his mobile so i'll ring him in the morning

adjust the little screw on the n75 a tad i turned mine clockwise and it feels like it pulls more and smoother power and it blows off more pressure (as i have a splitter) dont have a boost gauge as yet to tell you any mis behaviour.

i wasn't sure that was possible :huh: tho i did wonder why that screw was there
-
you can tell how old the N75 you have is, there are 4 numbers stamped on it, first two are build week and the second two are the year
-
show me this screw
Tim it's irrelevant, all the C's are old anyways lol

why patch what wrong with your fuelling?

show me this screw
Got an N75 sat in front of me and no sign of any screw :lipsrsealed:
-
that was my thought... never seen one myself either and I have 3 in the car (not including the one being used at the mo lol)

Perhaps what some people thought was the N75 is in fact something else :laugh:
-
there is a screw its on the top where the metal hardware is, there is a little hole and through there u will see a slotted screw head.

So there is :embarassed:
What exactly does turning this do?

I'm tempted to play with it and find out lol

Found two articles, that explain tweaking n75 on throttle cable cars is not reecommended, where as on the DBW it alot safer, plus alot of talk about MBC (manual boost controls):

nice find mate cheers, I'll have a gander at that when I'm not on my phone. I wonder if the one I've just taken off has been played with at some point and isn't actually faulty...
