Turbine 1.9 jtd 140/150 hp 16v hybridized on the 1.9 jtdm 8v 120 hp

quite well, and so much lag,then solved by the map of course!

could you give me the data of the turbine that you have mounted? i.e. serial and how to keep the pressure?

I'm looking for..give me a p? of time! ;D

[nasone147]

so, my original was a 777251-1 while the one I have now,hybridized,should be a 716665-1!
I have just loaded a new map,if I can tomorrow I do a log and I'll tell you ok?

the overflowing and diametrically opposite to the choke Sandro....
in the phenomenon of the choke, and as if the compressor goes in "apnea"or more precisely undue oxygen ante and true that you parladi "choked flow" ...
the overflowing and a sovraflusso of gas that the turbine is no longer able to dispose of properly and losing most of its efficiency....the term overflowing ? one thing "coined" from me to try to understand a p? better the phenomenon, but the exact term ? always talking about the turbine referring to this situation: unchoked the cio? "the air flow is not throttled" precisely
I am attaching a map of a turbine gt55 as you can see the variation of the ratio A/r varies the amount? of gas, that the same turbine can? "treat" remaining in the field, 80% efficiency...

I looked at the data of the turbines, the current 150 1.9, the latest facts say they are all with the relationship trim 50.1, like my old turbo, but with 6+6 blades on the impeller, I wonder why they have adopted this structure, require perhaps the most pressure? I was not able to find the diagram of the compression of a gt1749qualsiasi with trim 50 to see the substantial differences, although I think that even this although with trim less of my current exceeds 1.6 bar of boost.

I also do not understand the difference between adopting an impeller intake to 5 or 6 blades.

uluima my question, the current impellers exhaust for 150hp are the same as the code to those of the 120, while the 140 I I ? slightly smaller, but of very little, who knows why this choice

maybe thanks!! so let's see if the data mass air flow sensor return, for the record, we pave same turbine impellers and we are passatientrambi turbine trim, trim more, at least we can deal

damn you Patrick...you want to own all the secrets, eh?
and as a matter of efficiencies...
however, for the blades of the compressor, I can make an example simple enough if you have a fan with 4 blades and one with 5 second you equal speed? and sizes which of the two moves more air??
of course, the second then the more blades there are the more air, the Tc can't move...then a Tc with 5 blades give you a p? less torque than one with 6 blades in the same circles and with the same pressure preche the one with 6 blades fluira a bit of air in the most...
the reverse of the medal for? and an impeller 6 blades and more heavy a 5, then the Tc will have an inertia greater and one spool a p? the worst...

eeehhh munro I love to learn!! I am studying and studying dozens of pages, I have to go take it from a dear friend, a degree in fluid mechanics, a book on turbomachinery, to better understand, at the bottom are a electronics technician, my knowledge of physics, unfortunately, have a limit, and permit this doesn't ? lavboro, but passion, a great passion for the engines that I had since I was little, even if I had a bugatti veyron I modifcherei however, for the pleasure of it, you know?? I in the blood, and I love to learn, and of course, teach what I know to others, without secrets, like you do with me and I promise that when I'll have the chance? in every area I will be happy to return this huge favor!

bravo..bravo...we are on the "wave"

tonight I fixed the map by placing the map of the duty cycle of the geometry, now it stops at 1.4 with peaks of 1.5, I am injecting 105 mm3 of diesel oil and a bit of smoke; hence, obviously, c'?, pero I have to say that it's a much better and stronger now than before with a peak of 1.6 bar, tomorrow I do another log with the new map and I see as I'm in the diagram of compression and if ? increased air flow in the room,even if I think that the filter ramair that I direct towards the mass air flow sensor/turbine face distort a little reading mass air flow sensor, I have the sleeve siliconoco of 24 cm, then the mass air flow sensor and immediately after filter ramair with a curve towards the side next/above
