did it happen to someone..

(sorry my bad technical english,.. I hope taht you will understand)

the turbine on the "hot side" of the turbo core.. has simply disapear.. or melt...

pratical result... broken turbo on the turbine hot side.

what could make such damage result?

diesel injection exceed? with not enough boost...

could it create such heat.. that "simply" desapear the turbine?

the ECU map.. is not the original.

thnx[:)]

Hi,

sorry boring you all again.

did someone broke a Turbo with exceed diesel and less boost?

could that generate such heat in the hot turbo core that the compressor wheel simply "desapear"... by the exhaust tip. [8)]

thanks again.

fLAVIO

ps: does someone know where Allard make their turbo?

Sorry I can't help you about the problem you have but would have thought it must be linked to high exhaust gas temperatures?

I think that Allard source their hybrid turbos from Grundler Motorsport www.all4tdi.de

Never mind English - to understand their site you need to understand ze Deutsch[:O].

How did it happen? Were you finding out your top speed or something similar? With the power figures you seem to have, its possible that you indeed melted it away. The EGTs can get too high on these engines when remapped to "maximum". Are there visible damages to the outside core of the turbo?

When my PD 130 was remapped again a couple of months back, my tuner advised not to try to find out the new top speed. Its now fuelling so much that EGT becomes a problem. Not a problem for me, as I usually try to do only short controlled burts [:D]

no TOP SPEED finding at all...

just vanish!!!![}:)]

that?s why it?s strange...

the turbo maker... told me that the problem.. was too much diesel on it...

my pressures was 1.6/7 bar maximum.

the turbo spec.. was 2.5bar NO PROBLEM!!!!

the car was a little bit smokey in high revs and when I was in 100% charge on the "pedal".

he says that the problem is of the tuner.

I will post the tuner answer... in a couple of days.

I am in the middle of a war here...

too many people in the make of the car....

Tuner, MasterMechanician ,Turbo maker.

...and I... always spending money...[}:)][}:)]

cheers fLAVIO

First of all, sorry to hear about that flA.. [:(]

I think it's extremely important with your current level of power to have an EGT probe and gauge in order to keep up in real time with exhaust gasses temp and be aware of reaching dangerous temps.

Here's a nice EGT gauge DIY guide: http://www.dsmtuners.com/forums/showthread.php?s=&threadid=88370

Of course now it's a bit too late anyway, but it's very hard to say exactly what might have happened.

Best of luck (boa sorte!)

it?s not Allard Turbo, and not "miguel" tuned...

The Turbo comes from "Miguel".. or "miguel" specs [:p]

suddendly.. when the problem comes.. it?s nobody?s problem...

and all the "garrantee"... and "if you have a problem"... "we solve"...

yes.. of course.. "I solve"... paying for a new solution.[}:)]

Rui..

I know "all" about that of EGT,... but I know me... it?s not about that.

does someone from here.. use TDynamics Hibrid turbo GT1749b?

or Allard?

comments?

cheers, fLAVIO

Rui-> It?s not public yet, I will ask you to be discrete (for the moment)

It will be Public... [:D]

HI...

I think this obeservation is not very fair... many people read this forum and some of them are angry with these statements...

I will explain the situation because I Know the turbo very well... There are some turbos like this in Portugal... Not even one has broke or give any troubles... Suddenly appears with a serious problem...

Should the seller of the turbo give a new turbo to you fla?

Of course not... The turbo is damaged because the heat was too much in the hot chamber... Not because of the pression and not because of some flaw of the turbo... The reason is to much diesel and few preassure to deal with it...

I don't think is fair to say that "and all the "garrantee"... and "if you have a problem"... "we solve"...

yes.. of course.. "I solve"... paying for a new solution.[}:)]

"...

But it's in your right...

Hello HappyMike and 1st of all ...welcome to the UKMkIV?s Forum.

because I didn t point directly to anyone.

It?s me who is angry and very sad with the situation.

what I said.. was in anger to my self and to all, not for a person directly.

If it was, I would say so.

its for the situation...

a bad and hazzard situation.

that in the future or near future will not happen again... righ? HappyMike

HappyMike is one who is helping me solving this issue. [:)]

thanks for passing by.

cheers, fLAVIO

it's referred-to as "over-boost" - i think.

If your map spikes fuelling at too low RPM (below 1500), and the turbo has not spooled-up properly, this can cause disintegration of the turbo blades by allowing the turbo to over-rev under low-load.

If thats the case then perhaps having chosen the larger VNT20 hybrid has left Flavio more exposed to this risk - having a smaller VNT17 hybrid will spool up faster.

The big problem with Fla's car wasn't the choice of turbo... I have a vnt20 in my pd150 with more than 35000 kms and 0 problems... But I have a good electronic that balances well the fuel/pressure... That didn't happened with Fla...

He didn't have overboost... The car was always doing the same turbo pressure... That is not normal... The only thing that changed with the rpms was the fuel injection... But it didn't have enough boost pressure for the fuel injected...
