hi to all .. known presence of this sound coming from the turbine with the engine at 700 rpm, not touching the accelerator..
the car has no dpf egr , exclusion from the map correctly made . Turbine new original gtb 2056v ,2 weeks of life.
From the first day after the installation I had always heard this strange sound , the file attachment is playable with VLC media player or similar .. recorded with mobile phone . thanks
The turbine and regenerated? May be the impeller deformed
1: no , not remanufactured , and new warranty
2:you would do first if they haven't been able to hear the file before posting ..
Are with a cell phone...I will warm up
the hand on the turbo is up to scratch? I mean the pressure gauge...
He has me ? success with a new turbine that is mounted sibillava to low....removed and returned back to replace another all ok
I have to say that I have not heard the file, why? I don't yet have permission to download the file, but if you can't describe, maybe you can? understand more?
But the car goes well, I intend to performance?
the reason for that ? changed what??
S? nothing strange about that ? happened to m? to replace with new and then hear the hiss, to tell the truth on those audited for?.
yes , the prex of the turbo, and 0
ah .. I forgot .. with the dpf did not feel the sibillo glue turbine old
with the turbo that I have taken 2 weeks ago, sibillo, and is much more pronounced and noticeable, and then x all those that are not able to hear the file : the sibillo is not constant as the noise , salt and then falls to the tone of the sound , as if singing .. or even better : change the frequency .. as if it was going from the note 'do' to 'I' and then back .. may be manifold, clogged drain, or laundry? also xke' this hiss then full pull becomes a whistle powerful, especially after the 3 thousand rpm as if there is a false air or cmq problems with depression .. not sure the circuit of the strokes in the prex xke' of pressure is 1.5 bar.. if it should be broken a sleeve or creppato the intercooler does not end up on prex.. so I have to say it is a problem with the exhaust ..
It is possible that the prekat face this mess ? being broken and stuff like that..
I want to glue the map pulled 240 hp, whistles much earlier and much more to ****the volume
Not to mention the smoke that is ...
P. s egr capped and excluded from the ecu , not dpf +map is the original ( as a power) is pulled , intake manifold clean , the swirl I left intact
Could be a valve game half-broken/detached that is the whistle? also xke' the whistle you hear right next to the passenger compartment of the car .. not that you do below , but close to the wiper..
Strange, but have you seen if, by chance ? the exhaust manifold that vents?
In these cars ? metal andif the manifold ? the deformed vibration of the gasket that you put in "play"
I.. by removing the dpf... I started to hear a slight whistle in the starting.. (not the minimum), we say from 1000 to 1500 rpm..
then when I put the flange to the egr noise and increased...
from the way you describe the noise (near the cockpit) would seem to be the egr or intake manifold spouting... (I've heard the audio.. but you don't know where it comes from)
I have already read in the internet.. people with prisoners of egr sfilettati... and vents in that area... even a friend of mine.. and found the inlet manifold "melted" i.e. it was cracked... it's talking about the plastic version but'..
