13.5 s6 http://www.roadandtrack.com/new-cars/road-tests/reviews/a13037/2007-audi-s6-1/
13.4 S8 http://www.motortrend.com/news/2007-audi-s8-2/
Again, I would love to see some results. I could be absolutely wrong. Just from feel my car felt a little weaker than my e60 m5, and that is a 12.1-12.4 car all day long. Again it’s all bench racing and means nothing. But I wouldn’t be suprised to see one of these properly modified beasts well below 13.
Thats what Im talking about none of these are actually tested. They are just restated. The one test for the S6 was measured with a roll out test in a v box. This was a big issue with the S5 4.2 the same mags posted great results. A member from the fourm actually sent a email asking for the time slips. They responded with the rollout test results. Turns out its the same issue we are seeing with the S8 and S6 inflated results.
So far all we actually know for 100%
is two people on this forum went to the track and 14.5 and a well cleaned new intake car with all the maintaince went 14.0. Drag times has something simular. Again I cant speak on your car I would just say aside from your car I have seen nothing in actual testing that shows any of these cars are even close to better then 13.7. Add in the RS4 exmple and consider the facts it makes sense that we dont see faster times because the cars were never putting up faster times.
So far I think for me. It makes sense to take what we actually have from actual people taking there cars to the track.
Back to your rs4 point. Isn’t it more like 600-700 (3700 vs. 4300-4400) lbs differences and weren’t there some published times in the 12.8-12.9 range for the rs4. If you factor in the weight difference, and ratio fail, but 30 more hp in the s8 don’t you think 13.2-13.4 would actually be feasible?
. If I were to guess his before time with no maint or mods done was 13.9-14.2, and CV post mods times are 13.0-13.3. Just a wild guess though! Your right though , let’s seem some real data points and stop bench racing 
I’d say 13.0 is more accurate. At 107-108
We have 4 stock rs4s that went 12.x on our list form just dudes driving their cars. Magazine pros like at road and track also put down some 12.8-12.9 times.
If you added 600 lbs to an rs4, you’d run 13.5-13.6@101 or so on average.
If you took away the manual and threw in an auto maybe 13.7@100-101.
Thats where a really well driven stock s6 should be if it is really 600 lbs heavier. The RS4 weighs about 3850.
Those are not done at a dragstrip. So there’s potential for wonky results. The magazines generally use a vbox which assumes a full foot of rollout (rarely will you get a full foot of rollout at the strip). Vbox times also can be ways off and the altitude measurement can be off by ten feet (I posted about this on the 60-130 thread on 6 speed and everyone was shocked to learn of it). Imagine one guy running 10 feet downhill and the other guy running flat? Or imagine starting on a 10 good high gradual ramp ramp vs flat. I know who I’m betting on.
Then they correct the results for density altitude to 0 feet (no idea how they do that accurately) .
So their results are a nice guide but sometimes are unrealistic due to test environment. When we try to match them are useless.
13.1 from an S8 is ambitious as fuck. That’s erasing the weight and transmission handicap, not to mention gearing.
Don’t forget the magazine test where a stock TTRS went 12.1. Same problem. We’ve never seen a stock TTRS anywhere near that. Primetime, one of the best drivers on the forum, needed a tune to get there.
This is exactly what I was talking about. in the not real testing test. The corrected measurements that they put in and over all vauge outlines they use can be extreemly missleading. The other thing I was talking about was just restating the estimated times. Thats what it looks like was going on.
I deffinitly didnt want to be debbie downer but none of the data backs up the claims and the range for these cars seems all over the map. The facts right now support the v10 S6 and S8 cars actually running in the 14.0 to 13.8 range.
Sadly these cars are not like the RS4 and S4 that all got real track testing.
This is in the nature of what I was talking about. Benchmark wise I was using this as another supporting point to help give some reality to where the V10 cars actually sit performance acceleration wise
Yup. Splitting hairs, on dragtimes there is a 13.7 for an s8 and 13.8 for an s6. Not sure how valid they are. I would also say that 0 to 100 or the strip overall is not exactly where this car shines, but on a roll it is decent for an awd car. And obviously the throttle respons and power under the curve is nice especially on a winding road with long sweepers.
This is all rumors but back when I was debating headers 2 years ago someone said that header back exhaust plus the other goodies and no FI was putting these cars in the very high 11 low 12 range
Again, nothing confirmed just remembering back to some conversations on potential. There were Allegiately two or three running around CA that were nicely setup. CV may even be aware of them.
Cn: where are the before and after times so we have real data points to talk about
Your right. The best thing is there is a future now for the v10.
I too think headers for these cars is a game changer. You can read from Audi they mentioned the car would be making better power with headers
Which has me excited about this car now that it’s reached the price point for people who tend to modify them.
One thing I have noticed is that the platform grows when the membership works together helps identify the best direction and helps support everyone to get there.
Other platforms it turns into a mixed bag with people going in all different directions. Its good to try things and test things. But with the collective membership works together it helps advance the platform
Lots of performance talk. In the real world testing, I have yet to see an S8 do any better than ~13.9 maybe 13.8.
I saw the one on drag times, but there isn’t any real information on it. It looks like its just posted information with no time slip or 60 foot time. Drag times puts in filler times. That appears to be possibly one of them.
Here is the control car I used for testing against my car.

He wasn’t able to get into the 13s just very low 14s. I’ll post more on that when I get a chance to
You don’t think that anyone ever did better than 13.8 with these cars even brand new? Same with the s6 I assume. Might be right I figured 13.4-13.7 would have been reasonable to expect from the s8 s6 Crew. We will se I guess. I must have been a real optimist when I thought my former c6 was a high 12 car with a proper exhaust? filters and all maint done, but sure as hell felt like it coming from an e60 I was disappointed 
maybe a stronger one?
Please show a timeslip of any 5.2 S6/8 car running 12 or 13.anything . Supercharged even. I mean if it ‘must’ have happened, there’s a timeslip. So let’s see it.
Just as eager to see one Sak just telling you what it felt/drove like compared to other relatively quick cars. Means nothing, but in for the header back exhaust time slips which I think (hope) will be <13
Buelller :
Bueller what. We are waiting for the timeslips.
It might not be a bad idea to create a comment thread, to move some of the performance questions and thoughts to. I think that is an important conversation that needs to be had, and it would be good to have its own thread.
Afer all, we here, are actually the only ones doing testing and documentation.
There are wild ranges on what these cars actual stock potential was. No actual testing was done and when we’re all doing real world testing now the real world testing isn’t backing up the before talked about but never validated results in 1/4 mile and other acceleration tests
When the overall results come back and are posted it will be helpful to have some of that sorted out so we know where our cars total overall expectations stand.
What do you guys think? It looks like we have proof that these cars are all in the 14.5 - 13.7 ish range stock. The S8 and S6 seem to be about the same performance wise. I think its possible to squeeze a low low 13.7 with an extremely healthy car. The ET can range depending on conditions but we’re talking a 103 104mph car in the 1/4
Sounds very reasonable 
I know from reading that one of the possibe hang ups you had with the range we are talking about was how your car performed . Not having taken it to a drag strip you had the feeling only to go off of and I said it a few times. Your car might have been one of those cars that reallly breaks out of the mold. In the S4 platform we had one or two guy that had cars well outside of the performance range of the other cars.
I think the range of 14.0 to 13.7 is realistic but there is always going to be a few cars that just run a little better. I think one thing that might be keeping a lot of these cars in the 14 sec range is the lack of maintantence on any of these cars. Add in the broken intake issue most dont know about and then the injector and carbon it makes sense on where the performance is at now
Agreed I would say I was very aggressive with maint, maybe too much so.
Perfect maint plus nicely done exhaust and filters and brand new IM and injectors,hand carbon clean etc. and the car was much better than when I purchased. My e60 m5 which had full exhaust and tune was only faster above say above 75. Up to that point the s6 was much more enjoyable and much more tq, and I preferred the deeper exhaust sound. It was a much tighter overall package and it didn’t drink oil and u could get 23-26 mpg vs 17 on hwy and tank was 18.5 vs 22ish, you could see needle go down as you drove the m5… I still love those cars and would consider a 6 speed again but compared to the s6/s8 it was like mainting a Aston/basic Ferrari vs a Lexus.
