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

[tidus1985]

From the site of the garrett says that trim pi? the top parit? other parameters improves the flow d air, and then you tell me that the old turbine could get more?? We speak of the trim to the intake right? And the exhaust, what does it matter? It seems strange to me that this is the worst of the turbine of the series a 120 hp

[tidus1985]

Then this changes the size of the impeller, the minimum and not the maximum,the cio? the old turbine had the same maximum diameter and the minimum diameter smaller, it should work better with a minimum diameter greater than even if 1.8 mm

you d accordissimo ke and better, but if I fscevo the work to pull down the turbine it I that with 2 bars I was in full reliability...now in this guess as you say with a trim of 48 is able to reach almost 2 bars but I do not think is healthy turn with almost 2 bar fixed...but with an already 2056 remains in reliability? at least I think so..then everyone has his mnotivi for having taken that of the 140 maybe l had at home but he has spent money then a small upgrade without to get money there is

[tidus1985]

The fact ? I paid 150€ from a friend that the car was accident-free sketched some only cover of the actuator that I have, however, changed in toto was a bargain and especially because it was ibridabile.by simply replacing the nut

[tidus1985]

At this point I would just like to understand, hands on attachments munro, theoretically, that the benefits I have from this one to the old turbine, a greater quantity of air at equal pressure?

[angelolsp]

it is a qnt, he explained, you have more range d air and you can also have more pressure

[tidus1985]

then I found an explanation in English is satisfactory, in practice the greater ? the ratio of the square root of the inducer/exducer, the greater the flow rate of the air for a second, but the lower will be the maximum pressure, on the contrary, less ? the ratio of the square root of the inducer/exducer, the greater the maximum pressure but the less the air flow, this is theoretical when to change ? the part of the impeller exducer, while in my case the inducer ? more then I should have a better flow of air at a pressure similar to the turbine prior, since the height of the vanes of the exducer ? more than 2.5 tenths of a millimeter, then I would say that the flicker ? due to this, the question now ?, this flicker will hurt the turbine, the cio? the logorera or will only sot noise that I also like??

with regard to the 5+5 blades VS the 6+6 blades of the new turbine, which are the advantages?

[munro]

look at the maps of the turbo that I posted....
in the horizontal line of the coordinate you have the flow rate of the turbo in pounds/minute....
for all three of the maps having identical diameters of inducer (52 mm) and the ratio A/r, if, for example, go to the extent of 15 pounds/minute, you'll see that all three are identical cio? riescon to give the same air flow rate of 15 pounds just to change to? and the efficiency of the compressors identifiable through the islands in the graph that are central to maximum efficiency turbo...now the first two turbines, however, give about 22-23 lbs/min while the one with the trim higher by a little less..around 20 lbs/min.....what you need to look for? ? the vertical line of the chart turbo and ? the compression ratio of the 3 turbo said pressure ratio(Pr).
now if it has you need for your engine to es 15 pounds of air per minute at 1.5 bar pressure, which of the 3 turbines would be the choice of most logic??I ask you not to make a kind of quiz, but to make you understand better.

[tidus1985]

to the eye you would say the 3rd, the one with the trim on the bottom because it seems to work better at 1.5 bar if the efficiency part from max at the center and minimum out, even the second ? on the same one of efficiennza, and we obviously intend to 2.5 bar i.e. 1.5 bar of boost, + 1 bar of absolute pressure right?

[tidus1985]

pero let me also ui we talk about change on the exducer that ? properly the side of compression, it's obvious to most small ? the more the ratio, trim increases, but compresses less, in my case exducer ? the same inducer greater, I think, is a different condition, as you would have behaved the turbine in the graph lasicando exducer identical, but changing inducer?
