which to choose for 400hp charger?
hi boys, excuse the language but I are using google traslated, even if I have a different automobile, in fact I have a bmw330d 3000cc 6 cylinders 204cv but this and' the only forum where really they are elaborated motor 3000cc diesel in exaggerated way, I would want to climb on a greater charger of the my original gt2260v, I have thought about gtx3071r,,.. would not I want to have too lag, would I want to reach 400hp and sure son that my motor and' able these powers, you thing recommended me?
I now have above double ilo I upset 335d, small cioeuno that pushes in low and one great that pushes aloft, but since we have not succeeded in managing well the electronics on this I upset, I want to abandon project and to aim to an I upset single, the auto is now working only with I upset great, and' a hybrid k26 with cold in general gt2871, the wheel side warm measure 64mm while side cold measure entered 53mm diameter 71mm, have gone now in boost since 3500 to limiter but the maximum one it from on the 4000. now in base to these measures I would want to apply an I upset that me best a po the lag, would be also happy about 500 turns, that is' that it went to boost around 3000 turns, I am thinking about a gtx3071r because' it has wheel unloaded smaller, and' from 60mm and could I put an ar48, then everything on double pads I should have less lag, thing done recommend me you?

maybe there is some knowledge there.
what is the year of the bmw motor you are having?
is it very new? send us some pictures and more info
Nice body, tons of ridiculous mechanical issues - 300d turbo 82' /motor 85'
here is a 3.0L with the hx35.

ok, the motor of the my car and' a 6 cylinders 3000cc 24 valves, have now above the 335d turbochargetr but it don't work well, and therefore I want to replace him/it with a single turbocharger, however I don't want to have too lag, I am undecided among a turbocharger among a holset hx35 or a gtx3071r, the last one being on double pads I think that I would have less lag, here are the photos with the turbocharger of the bmw 335d

it does not work well with the 335 turbos because you don't control them properly....?
For sure you will not find anything better than this twin turbo on top as it is already installed.
Try to improve the control and keep the twin...
just my opinion.

do I have a bmw 330d e46s 204cv with 335d turbine, have we tried in so many ways, and' very difficult to manage the two turbochargers, therefore' I want to put a single turbocharger, you that you would recommend me? I have thought about a gtx3071r, I am now turning only with the great turbocharger the measures I am, unloaded ryuota from 64mm diameter. exducers 56mm, aspiration diamwetro rotates 71mm inducers 53mm, with this I upset I have too aloft boost, with gtx I should recover something in low?
The fast response you get of the R2S system you can totally forget about the Holset or the Garrett GTX
400hk seams not that trivial to get, the best I have see on BMW is 535D is 380 but the BMW has a little higher compression ratio so it could be possible but it is on the border,
How did you change the off set measurement between the Mercedes and the BMW cylinders since they are not the same?
and you do you guide the by pass valve for HP turbo and by pass valve for the HP turbo on the air side? I have a document you can see how it is handle on the BMW if it is of interest
Like tom said if this KP39 1873 and the K26 2871 is handle in the right way it works fine, I am planing and preparing for use it on my 270cdi but I am looking for c30amg nozzle but having some problem to find them.

, My bmw and 'of the CV 204 that I have an e46 three series, his/her centralina he/she doesn't succeed in managing 335d turbocharger, therefore, and' in use (the unicip) together with the memory you Know unicip?, but it is everything one failure.' I now want a single turbocompressore, gtx3071rs I am sure that it will give impulse to 3000 turns,
since most of the people here do Mercedes and I of some reason did not get out of my head that you did BMW, even if I saw on you picture it was BMW and read it with I can not explain further. I already got 5 new 535D turbo to play with so I do not need another one, thanks anyway. Good luck in your projects
do excuse me but don't I succeed in understanding what you have written, do I use google traslated, at the end us someone who can help to understand me that turborcarger I must use?, yet on used mercedes many turbochargers without varying geometry,to work with I upset of series and' a thing, the memory succeeds in managing all, but to put turbocarger 335d on a motor e46 204cv and to manage him/it and' difficult
Regarding turbo machinery many turbos will work, but if you want drive ability I recommend you to look at a VNT, if you want broader operation range and faster response go R2S like you have, but controlling is just not plug and play, it need some basic understand in turbo machinery and making your system controlling it in the right way do not come by it self. If you want a even wider operation range go compound with VNT. But you need to have a target how you want performance, even tri turbo like the bmw 550d is one way to go, I am working on a similar system for my OM606.962
try two GTB2056vl it would give your 400 that for sure and here in sweden you can find them sometime for 400Euro, but is not plug an play...a GTB3576KLNR would work but bottom end would not be that great and they are not that easy to find if you do not buy it new, but then it gets ridiculous expensive..
But just any VNT is not good, if it is garrett GTB it properly has potential, GTC better, it gets less exhaust back pressure etc but individuality when you choose can give a lot of performance
try to read a lot on both www.superturbodiesel.com and tdi club there are a lot of information available
Google translator to communicate sucks, I used it in the past from Swedish to German language, the man said he was so bad in English so I used google translator, after that his English was understandable...

do I hope to make me understand, is it now my auto working with great turbocharger only and does not to complain about me aloft of his/her disbursement, want only to earn a po in low at least 1000 turns, replacing him/it with a gtx3071r they succeed in earning 1000 turns in low?, do you know unloaded ar of kkk26-gt2871? I have only measure wheel unloaded of 12 shovels 64 mm diameter, 71 mm diameter rotates - 53 mm inducers aspiration
I can say it is not that easy to understand exactly what you mean, sorry
The GTX3071R will not be even close what the low end of the R2S system if it is correct operated, I have sent a mail where you can see how the R2s system is operated on the originally engine to give you some input how to operate it.
I can say it is not that easy to understand exactly what you mean, sorry
doesn't ok, interest the operation I already know, and' the memory motor edc16 that doesn't communicate with control turbine 335d, do I now try to make me understand better, an example, does a gtx3071r, have less lag than a gt3271?,I am also thinking about something of the kind http://www.youtube.com/watch?v=REJzNx-Qt...re=related
VNT turbo keep up the C1u tangent velocity to the turbine, this make poor turbine efficiency since the delta pressure over the turbine is quite high in the beginning but it would get boost earlier, and the flow in the turbine do not that well follow the form of the turbine tips, a vortex formation gets a way since the reynolds number is quite low at the main flow and the re linking of the flow is high and dp/dx>0 at that stage in the turbine so to speak. This is some of the reason why a R2s system will out perform a single VNT at the same level of technology and the purpose it was created to specially lower exhaust emissions and at the same time keep down cost, of course a new step is to use a one VNT or full two VNT. But VNT can have a problem when sot clogging in the mechanism
on your originally engine do you have a vacuum operated VNT turbo, yes?
on the R2S system you have
1 vacuum operated bypass for exhaust gas for HP turbo
2 vacuum operated bypass for HP on compressor side
3 vacuum operated valve for waste gate
By proper controlling this you first use HP turbo but LP turbo start to force feed the HP turbo to a level that instead of gaining more from the HP turbo you bypass to boost the LP turbo and eventually bypassing HP turbo complete and at that time bypass of HP turbo on compressor side, at this stage this need to be must be completed. and at even higher load start to open waste gate on LP turbo.
If you run the HP to long you will over speed it and it would not can except building up exhaust pressure

Yes you can do like that, but it would just show lack of understanding of turbo machinery in my personal opinion
sound performance has another one...
GTX3271R would be less lag the GT3271 since the first one is ball bearing and has upgraded aerodynamics for the compressor part. But understand that turbine need special speed on the exhaust gas before start to build up boost,

excuse me but I have understood few things perhaps the only road and' to use a double turbocharger vgt, the gtb2056vl, and' a po difficult to find, gtb1756v I could find to good price...am I sure that gtx3071r will give' good results with boost around 3000 turns, however' I am insecure which to use unloaded ar, or 48ar or 63ar?,I could use on ar48 external westegate from 38mm to help against pressure unloaded, to end I would want to also climb on water methanol,
See what happens if we run both turbos to a PR of 2. Big turbo brings boost up to 14.5psi (which corresponds to a PR of 2 at sea level), it's size must be chosen so that it makes 57lb min @ 14.5psi, haven't checked exactly, but it will be a GTX3582 or something like that, then pushes that air to the intake of the small turbo.
Now heres the compound trick: the little turbo is also set to 2 PR.
But it's already got 29 psi (absolute) pushing into it. So it puts out 58psi absolute, minus sea level pressure, so actual boost is 44psi, but doesn't spin any faster than if it was used on a conventional engine boosting 14.5psi. A flow correction check must be done to verify that the small turbo is now putting out the 57lb min, given that it's intake pressure isn't atmospheric but 14.5psi. A GT2554 perhaps?
In a nutshell: big turbo, aka the low pressure turbo, takes boost to 14.5psi, small turbo, aka the high pressure turbo, takes boost from 14.5psi to 44psi.
But both turbos run a comfortable, easy 2PR.
Result, same response at lower rpm as the small turbo would give, but with the topend airflow of the big turbo. And the biggest advantage: very low charge air temps. Because neither of these turbos is overstressed or even near its edge of the compressor map.

doing put a greater (gtx3071r) turbochager I would also be able riprofilare cams to improve to low turns that I/you/he/she think of it? this and that that a friend proposes me, very easier to manage some system bmw335d, me however to the place of the gt2560, I would put a beautiful gt2260v for the lower part, here is thing says the message of the friend.......( Ok quick example: let's go for 44psi, about 450hp on a 3 liter. 57lb min of airflow required.

boys from my parts and difficult to find eaton m90, have I found alone m62, to combine to a gt35 or a holset hx35, do I think enough chesiano to do on the 400hp, did I want to know if the m62 supercharger and' some small, has found two types, that with electromagnet and without, does the first one have a pulley a greater po and and' difficult to find a smaller of it with electromagnet, thing recommended me, can m62 go?
