Single turbo S4 is out....

[elijahallen]

thought some of you would like this.

Say it on AW earlier. Pretty neat. Never really took into consideration that you can route the manifolds like the y-pipe.

Pretty fast for a base tune and 22psi. 4k full boost makes me feel pretty good. I am hoping to see full-boost by 4.5k, but with a higher redline. Nice to see someone tuning on ME7, mafless too!

[fixn2xlr8]

Interesting, Im not sure how I feel about the exhaust route. (not that there is much choice) but its interesting.

[Das General]

I don't know how I feel about manifolds going directly over the fuel lines. Heat wrap works, but I would have some concerns.

[djwimbo]

I would think that a Standalone and deleting all the B/S under that hood would help a TON. I agree about the fuel lines though, inevitably the fuel temp will go up.

However, props to those guys for what appears to be a well built setup. It looks reliable, time will tell.

[highPSI-S4]

It doesn't look pretty. But it's to the point and functions well. I want to see it run.I like the good things that are becoming of this platform as time progresses.

[Das General]

Is he running 2 turbos with a turbonater intake?

[djwimbo]

Is he running 3 turbos with a turbonater intake?

He drank 3 cans of NOS energy drink too before he put those clamps on too.

[PSI NRG]

Interesting concept. Although I think that it will produce wayyyy too much heat and being close the the fuel supply is risky. None the less if it works mad props

[Big Boost]

Looking closely at the fuel lines and how well the exhaust piping is wrapped and then covered again in key areas with a different insulated heat shield, not to mention seeing how well the fuel rails are wrapped too, heat soaking occurirng in the fuel lines might now be much of an issue. The owner could use a laser thermometer to show what the temps are after a beat run.

Pretty much on the same lines as the remote turbo system but on the top of the engine instead of underneath the car.

i was thinking a remote turbo setup would be cool!!

I almost built one 18 months ago before i did the twin, the reason I didn't was because you still had to do the same amount of work or more on the install as the regular factory location...

[Outkasted]

I thought you would be able to build a sequential system using the remote idea, but i never knew if it would actually work and don't have the funds to try and fail.

[FLACO X3]

bad ass
<---- waiting for someone to say "he should just done k04s"

[Das General]

2.8 FATS on 22 psi, on the very first tune!

MUAHHHAHA!


Needs to go to the track to see the real deal numbers though.

[BurnAll4S4]

im not hating on the single turbo thing...but they could have done something a bit different with the manifolds......seriously. looks like hog shit.

results look good so far though.

[revhards4]

I dont want them to take this the wrong way but, it's gonna catch fire soon if their not careful.

I love the performance results from the single turbo. I just wish there was a better way somehow.

There is a better way!

And Roberto: I agree, it does look chincy. But at the same time,

performance > looks.

And you would be a hypocrit with your fancy MB clk wheels!!!

[NYCVR6]

Damn those fuel lines make me nervous.. Very cool, love seeing different shit.. Decent way to run a single without having to hack the car up.

[2001S4NY]

i want to see this car after about 5 multiple runs on the highway with no cool down. Wont last long :(

The intake mani may start glowing haha.. Theres a lot more work involve then people may think that you cant see to run this setup as we both no.

[JaredVL]

some of the people in this thread are stupid, just sayin

the setup is fine

props to them from someone who knows first hand the hurdles of not just rolling with what the audi engineers laid out for you

Derek, cone filter on the turbo, and EGT delete would make my life much easier...

You need to get in contact with a few tuners and see what they can write out for me... Including all that bs Audi put in there for boost control / evap crap, as well as the MAF and EGT...

Big for single turbo S4's

[GURUMAN]

It makes the other Single turbo thread look like a fuc?ing joke...

[Militant-Grunt]

*waits for thread named single turbo s4 burns down*

I don't wish it upon the guy, but once that exhaust starts glowing and starts melting rubber fuel lines then GG.

[AudiA4_20T]

Wait.... Wait.... where are all the people that said it wouldnt work....?

[Das General]

I like the o2 in the manifold setup. Allows you to read the individual banks, which would be tough to do with one downpipe.

This setup makes me juiced.

Jake: I'll PM you about the tune. EGT's and rear o2's won't be an issue.

Anyone know if a mafless BW turbo will throw off the harmonics? Enough to mess with knock sensors?

[317ssayzarc]

Harmonics? From a MAF... Come on now...

I was told Mafless will be tough since S4's are narrowband, which is shitty... I assumed they were wideband

Looking at his timing and timing pull, things got issues... It's running low requested and still pulling 10*!!! Just noticed that for whatever reason

[Das General]

Nevertheless, I am pretty impressed with the overall setup.

Well running K04 cars and RS6 cars have been noted to run sub 3 sec' FAT's. Granted they are similar to CAPS times and don't necessarily mean a whole lot. At the same time, it still does show some relation of power.

I think the turbo choice is pretty solid with an unbuilt motor/head. I would be interested to see a race file for this setup...and whether or not it survives.

[2001S4NY]

MAF less can be done, if Derek wants to do it he should the only problem is it will take a little more time to tune. But would be a sick setup with no MAF :) Every time boost is changed the tune will have to be altered a little.

[biketsai]

I wanna see more pics of the exhaust manifold setup, it looks confusing!

[Unispeed]

I am still confused though as to the manifolds.. are they using the stock manifolds and just bolting all that exhaust piping to them.. or did they build their manifolds from scratch.

I think that will be the plan. I am only a hop and a skip away for a tune adjustment. BUT my setup will have a ton of space to include a MAF and large intake.


Like I've said before. I am very interested in the pre-turbo o2 sensor setup. I always thought it would work, but was somewhat skeptical.

[2001S4NY]

well if you have room for MAF then put it in will save a lot of time on the tune

[Das General]

It would be tough to use the stockers, as their flanges are directed towards the tranny. If you notice, each bank has their own primary going past the valve covers, which connects to a pseudo y-pipe (middle of the intake mani).

My guess is they are completely custom.

[317ssayzarc]

We don't know how much room is there Derek, or what MAF will be used...

O2's preturbo are fine, but the further downstream the better so you don't cook em... I'll put em in the 2nd part of the manifolds, the Y piece

Well, presumably, if the compressor side of the turbo is facing the passenger side of the car... there should be room to connect a MAF and intake.

For the break-in process the 85mm will have to be used. But in the event that we decide or need to use a MAF, I would opt for a 90mm, which I would imagine, would fit.


I want to hear that BW screaaamm in boost.

The o2's would have to be right before the y-pipe'ish section.

[317ssayzarc]

I would love to stay up and talk single turbo... BUT, the word on the street is that a badass A4 needs to be driven tommorrow...

[mike-2ptzero]

Wait.... Wait.... where are all the people that said it wouldnt work....?

LOL, like this is the worlds first single turbo S4.
