Title: MAFless A6(C5) 3.0 biturbo GT2860RS
Post by: SeRiLLo on October 30, 2012, 09:09:21 AM
From the beginning, the project was built as a show car. It's not sport, rally or drag car. It`s urban fast show car )) And all technical solutions applied in this project was aimed at achieving these goals. I did the whole car with my own hands. Starting from the motor assembly, welding, finishing with electronics and ECU tuning and programming. MAFless, noN249, noN335, noSAI, noRearO2

А зачем улитки так размещены? Вроде как и гораздо более большие влезали в нормальных позициях?
Такой разрез в капоте наверное только в России прокатит, в любой цивилизованной стране гарантировано что дальше первых ментов не уедешь )))
А так видно что ты очень старался и всё делал, за это зачёт, продолжай в том же духе.

Правда мощность немного маловата. С этими улитками должно быть возможно снять заметно больше, чем 600 сил.
Во что на данный момент упираешся? УОЗ маленький, ЕГТ лезут? Какой наддув?
Я думаю что если устранить затык, то должно получится за 700 моторных.

English:
I questioned the placement of the turbos and said that in a civilized country you probably would not get very far with your car's hood looking like this.
Also noticed that it seems a bit down on power for the high flowing turbos and asked more about the aspect of the tune and the bottleneck, as it should be possible to reach 100hp more and certainly all the other components in the car seem up to the task, as everything has been carefully built with a great power reserve in mind.

28rs are not high flowing turbos ))) As i said, this is a show project for the first of all. It`s not all day car. 630hp is enough for this project. And max power is not the primary goal. I can show about 700hp but it would be possible limit for 28rs turbos(350 hp for one on 1500cc). I tuned on the subaru dino and it has bad for FMIC high level air cooling. For this reason IAT 50*C. If you're interested: 1.9 boost at 6000rpm, 1.75 at 7000+ rpm, IAT growing to 50*C at 7000rpm, ignition 11-12* from 5500->7500, ign. retard -3*, AFR 10.5-11, EGT 900-930, 98 octane.  If you say that I can make 750hp on 28rs, then let`s talk about it...


Собственно ты понял, что без отжатия турбин и углов на максимум ничего не получится - они тупо затычные. 700 - вообще предел при условии злых углов и низкого IAT

You need Aquamist HFS-3 with dual 1.0mm jets :)
I have this on my RS4 and I could instantly run 5-6 deg more timing across the range.
1.6 and 1.45 bar to redline on little K04's.
Also no more problems with EGT, and hp went from about 450 on pump to 500 on pump+meth.

The meth kit will give even higher gains to you. I think you can have reliable 700hp then.
The biggest gain with it is the fact that the car is always fast. Does not matter if it is summer or winter.

Without meth injection my IAT were 30 and 60 degrees at redline.
Turn it on, and the same pull was 30 IAT in a straight line.

i agree about meth, and i use it for the another cars. But this project does not accept any doping, at least for now. And I said it here http://www.drive2.ru/cars/audi/a6/a6_c5/elysey/journal/149425/#post
But I can easily install GT3071R with no alterations

If we talk about the power of stage1 RS4, some people make 530hp at 1.5 boost with no meth ))) we all need to learn from them )) lol

we do few 2.7 with 28rs and 2871 , from 28rs i hit 650hp on crank, 2871 682hp on crank , 28rs no problem to locate in orginal turbo place.

i now, with good air cooling i can make 680 this project no problem. The main purpose of a such turbo location is to do something that no one has done and easy upgrade to bigturbos for future

Try that with west coast california 91 octane.

Try that with west coast california 91 octane.
It is also completely unrealistic in europe, he was referring tongue-in-cheek to a certain forum thread on a certain forum and certain claims, ignore that :)
Most RS4's here with a tune, exhaust, injectors make 470-480 crank.
I have a decat and meth, and I rate mine at about 500.

The injectors really run out at around 450 crank. You just go to 100% IDC and fuel goes lean.

Yup. Even on 5 bar :/

Need 11.5 on 91oct :(

I don't know about 5 bar, I run mine with stock fuel pressure.
With 5 bar there could be more to be had from them properly, but then that's putting more strain on the pump.

I run 1100cc meth though, and it seems fine atm ;)
Anyway let's not over pollute SeriLLo's thread here with our off topic...

California gas sucks. I feel your pain as I have remotely dyno tuned a few cars.
However 11.5 is pretty rich.

this is interesting...  A6 2.7 ECU works with 551K File?? RS4 551F does not work with K File...

which A6 ECU number is it?

What about N/A 7.1 ecu's? I ask because you said any 7.1 with a 29f800bb, although I have been informed that this isn't necessarily correct? Not trying to hijack, just trying to get my facts straight.

I don't think so. 551K works on 551F, I don't see why it would not work the other way around.
The boot roms are identical. The ECU hardware is the same.

The only thing there is, is that you can't flash it in OBD, but with boot mode it should work just fine.

but not vice versa.

Pretty sure that is not correct. I have an emulator plugged into my RS4 atm, I will check this tomorrow or something.

Why would that help? 551F sucks, no misfire monitoring.
Just run 551K.

I made it 4 years ago. Many solutions are no longer relevant today, since there are i-pads and android pads ))) But if you interested I can tell about it. It is 10.4" LCD display with LVDS interface and resistive usb touch screen. And connected through LVDS-VGA controller. The PC made from micro-ATX motherboard with AMD 2core processor with integrated graphic chip. Power supply is custom made for automatic switch and off with timer then ignition up/down. Power consumption from 40 to 90 watts, depending on the CPU load

If you want, I can give you some software so you can make a realtime dash from ME7Logger input on your carputer.
Do you want it ?
In Winlog the gauges are fully customizable to whatever you want them to look like.

I am using this to tune my RS4 :)
