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

yes! the old woman, however, was gt1749MV trim 50

[munro]

from the data in my possession, however, to have a trim of 54 must have a exducer 49 and an inducer 36...
with a trim 55,1 instead of the exducer and 48,9 and the inducer of 36.3.....
this, however, and the compressor map of a gt1749v with a exducer 49 and a trim 55....
if you need a hand to style or for the calculations, let me know....

[tidus1985]

from the data sheet exducer 49 inducer 36.3 in fact, for the precision ? trim 54.88, I saw the chart, I understand that he can get to 1.6 bar to 180000 rpm,now I say to you, to me, makes them just peak then it's up to 1.5 bar, should be fine at 1.5 bar from the chart ? on the central area, I ask you then, nn are wasnít to find a chart of gt1749mv (trim) 49.86 and esducer 49 and inducer 34.6 that would be my old turbo so in order to understand the differences and see which is which ? best

[munro]

do not look only the pr tries to calcolarti, approximately how many horses you are and how much air your engine....
es if the ori have 120 hp calculation and 120 x 22(afr)x 0.35(bsfc)/60=15,4 lbs/min..

I arrived with is mappanad inject a maximum of 105 mm3 per cycle, so I suppose dinessere over 150 cvforse between the 160/170

I have read with pleasure the whole discussion, only a cpnsiderazione add this:in terms of coarse increase trim sposter? the line of the surge to the left, looking at a compressor map, this is realized in order to give the pressure pi? high at low revs, but more? the low to the high.

Hello sandro! Was expecting you to take action, for the rpm you mean rpm or rpm turbo? Seco, do you ? a good upgrade for the money spent 150€? Has not even the small amount of play on the impellers

A very interesting debate . thanks for condivederla . I thought I was a p? less in the details of that? mounts directly to the turbine + great .. but now I know that a hybrid ? much better ..

thanks

ok by calculating your "flow" on the air for 170 hp you'll 170x22x0,35/60=21,82 lbs/min of air of the request....
if pesumiamo that your afr is a p? more fat of 22:1 and let's say it could be around 17:1...
your request for air sara 170x17x0,35/60=16,86 lbs/min
if you look at the compressor map posted you'll see that it has almost 17 pounds of air per minute with a press of 1.6 are completely out of the map and the turbo and choking and pu? stall....this in the long run leads to the rapid destruction of a TC.....
also if you look at your press 1.5 remain in the zone of maximum efficiency of the TC but are still too dangerously close to the maximum rpm that the TC pu? bear...ah...1.6 you are more than 180000 maximum speed sustainable by the TC...
if it were my TC, I'd never turn so....the botto,TC, and around the corner.....

Good or understood, I would say that then I cinvuole a gt20/22, but to say la.vecchia gt1749 the original that I had so held even less theoretically with a 50 trim?
