Audi S6 C7 Stage 2+/ 3 Result Opinion

[Vanko0o1]

Hey all,
I want to start that I am extremely happy with the results myself.

The dyno the car was measured on is a Mustang Dyno.
Also the room temperature was 40 degrees.
The modifications are:

ECU + TCU custom remap
RS7 turbos + airbox + RS7 inlets
Custom Downpipe
The run is on 100 octane in Europe which would e 95 RON .

The future modifications would include a K&N filter and a JHM or MercRacing heat exchanger(still debating on that)

I really wanna hear what other people think of the Dyno graph.

Seems a little bit low, but that could just be the mustang dyno

A dyno plot is pointless as a method to verify performance and completely pointless without an accompanying datalog. Especially on a 4.0T which heatsoaks and on many dynos which have calibrations the operator can change and poor cooling.

agreed.

is the weather correction factor(?) +5% or minus 5%? I dunno here...


Lots of area under the curve for certain and the delta looks very noticable.

Isn't that kind of harsh? You create software intended to be the best on Earth and Barsoom, so need very accurate quantitative data. Maybe OP is only interested in a qualitative comparison before and after some hardware and software modifications on the same dyno with the same settings, for example to feel confident that everything was installed properly. Is that fair?

[John@DEADBEEF_DynoSp]

We developed 4.0T tuning using the best cooled dyno we could find on the West coast. It was still a heatsoaked nightmare and we got far better info with proper data logging on tarmac in a cool climate. So no, not harsh at all. Using it as even a before after without boost, knock, charge temperature logs is entirely pointless.

I found pointless to upgrade to RS turbos without upgrading transmission first. I was told by tune garage that even stock turbos are not a bit issue and they can handle 550+ BHP but the transmission will go first. The torque is too much I would say.

That's where a good tuner comes into play.

Of course someone who will actually spend time with the tune and do proper calibration will make the transmission last longer compared to someone who will just flash APR software and say you are good to go.
Still, if you run crazy launches everyday you will kill the transmission quickly regardless of good tuner or not. In the end it is also about the person behind the steering wheel.
I run custom Unitronic ECU+TCU tune on my 2018 S6 and I find it just about enough and save for daily use. I am about 550 HP and 720 NM and I have no issue to overpass anyone.
To my opinion if you want 600 HP and 900 NM just get an RS6/7 with better cooling and transmission and suspension and brakes. (Steel brakes on S6 are just shit.)
OP just asked for an opinion so I shared mine, you may or may not agree with me.

Thanks, that's interesting. Your logical responses are always appreciated and good education for me and others.

[Vanko0o1]

Thank you all for your replies.
I was just curious how do you find the results , since I have little to no experience with 4.0TT platform.

Your ECU tuner may be able to help you with data logging specifically for your car. When you get results, post them here for the experts to review.

This is just a completely unfactual statement. This is a 2013 mindset from when the 4.0t/DL501 combo came out. It’s a good litmus test to see if someone is actually paying attention to anything going on with these cars…

This is a 1000% accurate statement

Ok, I will forward this information to one of the largest tuners in Europe. Their RS3 runs below 9 sec on unprepared surface with street tires for countless times and they actually drive this car to events. They are not some shitty American garage tuner.
Sorry but I rather believe to them with experience in thousands of cars (Porsche, Lamborghini, Audi, VW) than to some random person online. They told me that many DL501 break down after 1,5 year and I do not see any point why would they lied to me, do you?
As I said previously, you may or mot not take my opinion but do not try to convict me in your "truth". Thanks.

Cool story bro, a 9 second RS3... Have you Seen what Iroz Motorsports is doing with those? Probably not, Im sure your tuner shop hasn't told you about them and thats the only way you can learn anything apparently.

And regardless what their RS3 is running, we are not talking about an RS3

If DL501 breaks down after 1.5 years then maybe you can explain to me how my car is 10 years old with factory clutches is running fine with 0 slip when I am running bigger than Rs7 Turbos and before that the car had Rs7 turbos before I even got it. So going on over 4 years with upgraded turbos. I thought they break down over 1.5 years? Then how is it possible that me and COUNTLESS of us are running BIGGER than rs7 turbos on factory clutches? I drag race my car and launch it all the time and my clutch is not slipping at all. Some of us actually own these cars, study these cars, build these cars and we don't rely on some shop to tell us about a car, we all have a brain we could use so why would I need someone else to do the thinking and the learning for me? We may have some untrustworthy shops in the US too, but even I havent heard any of them say anything as ridiculous as that

Audi rated the DL501 for 737 ft lb of tq or 1000NM so please tell me is this shop smarter than Audi?

There are also many people running over 1000 NM on a completely factory DL501. So where have you and all of the guys at that shop been while all of this has been taking place over the last 10 years? Its time to come out from under the rock. Theres Rs3 going way faster than 9 seconds, IDK if you guys have gotten word yet, you missed out on a lot

Now let me address the other piece of bad advice they gave you.

-Overspinning factory CAST turbos that will shatter and send pieces of metal into your intercooler/engine is NOT better than running upgraded BILLET turbos that are designed to handle high boost levels.
I shouldn't even have to explain why this is a bad idea...

You are free to accept bad advice i could careless if you listen to me or not. But dont spread the bad advice especially when you and your shop have nothing to support those ridiculous claims

Go ahead and keep trying to squeeze power out of your stock turbos long term. let us know how that works for you.


Edit: I just read that you have a Unitronic tune. I'm sure your shop telling you to stay away from stage 3 has nothing at all to do with the fact that unitronic does not sell one

Idk what boost PSI unitronic stage 2 runs but it might be a safe boost level for those turbos. or at least I hope it is
