What is the actual performance on the V10 S6 / S8

A6 All/ S6 All

Actual real-world performance results.

Before we get too far into the performance side of what all the mods now available for the V10 can do, it’s best we cover what the actual stock abilities of the V10 S6 and S8 are.

When you look at the S6 and the S8 on paper the S8 make lots more power and should be faster. That only seems to be slightly accurate. For the differences between the S6 and S8 check here.

As for the actual performance on a stock V10 S6 or S8. The range seems to be between 14.4-13.9 if you have a carbon clean a non-broken intake manifold great running car you’re looking at being able to run in the range of 13.9-13.7 in the MPH range of 103.

Some tracks and some conditions might help get a car to just dip a little lower or slightly higher in the ET but the MPH seems to all be in the 102 103 range.

When you read publications they say the S6 and S8 are much quicker. So far we have not had anything to back that up. Real world results show most cars are in the 14-second range. Several AR members have track tested their S6 and S8 cars and all came in the 14-second range.

A test done by Edmonds resulted in a 14-second run as well.

As mentioned later in this thread. My JHM tuned S8 crushes all these times by a large amount. So, there’s hope yet for the 5.2 V10

Below is open discussion on what we would all consider the actual stock performance range to be

#2

I see a 13.7 for an s8 and a 13.8 for an s6 on dragtimes.

Honestly, right after carbon clean, proper exhaust, new IM, and msds filters I felt confident my car was a very high 12 very low 13 second car in colder weather. Which would make sense if the stock mag claims of 13.1 and 13.3 are true.

#3

Your car aside. I dont think any S6 V10 has come anywhere near 13.6 or better. So far no proof shows thats even possible. No car and driver or car mag that actually tested the car got any results better then 13.7. I have a print car mag where they road side tested the 1/4 mile on a 08 S6 and didnt get better then 13.7. The reports of testing on the S6 or S8 for 1/4 are just re talked about talking points. None of the real world data stacks up to show this. They keep saying estimated times when you really dig for it. So far thats what keeps poping up is just some car articles talking about the estimated times.

When you see actual performance testing and videos they all show high 13s at best

Here are some other things to really consider. So far we have seen well maintained s6 cars after carbon intake and other mods get into the low 14s.

#4

After looking for a few talking points. Here are a few more things to think about.

The RS4 weighs close to 800lbs less but makes 420hp and 320tq. Its a manual with a better gear raito then the S6 or S8. Average test times for those cars are only 13.2

So when you look at the 800lb lighter almost the same hp 6 speed manual car with a better gear ratio do 13.2 its not conceveable to believe the S6 or S8 are going to be as fast. So far nothing proof wise has shown any V10 getting better then a 13.7. I tend to think thats about as good as it gets.

Now Im not saying there isnt real performance to be pulled. The 4.2 S4 runs 13.8 stock but with some JHM goodies and the JHM tune your in the high 12s.

Just something to think about

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/

13.1 s8 http://www.roadandtrack.com/new-cars/car-comparison-tests/reviews/a12058/audi-s8-and-lamborghini-gallardo-spyder/

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.

#6

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 :slight_smile:

#8

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.

#10

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

#11

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 :slight_smile:

#12

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

#13

Which has me excited about this car now that it’s reached the price point for people who tend to modify them.

#14

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

#15

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

#16

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 :wink: maybe a stronger one?

#17

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.

#18

Just as eager to see one Sak :wink: 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 :slight_smile:

#19

Buelller ::slight_smile:

#20

Bueller what. We are waiting for the timeslips.
