Very good!
So have you done the log what stage is you car at .

Any other takers to see what the cars are doing in comparison to each other to see if we are all making similar power in this hot weather.

6.83 at24.5c! mtm stage 3, fmic, balanced turbos, running on 97 ron(i couldn't find a shell site, they are very thin on the ground in my part of kent, they have been slowly taken over by other petrol co. over past 6 momths), hope this helps for reference purposes.
regards stevesmee

absolutely thanks .
I popped out last night and got some great results on vag com to put it all into perspective.
Great log great time. Glad your car is doing the biz.
What do you think of the test?
It is an easy way to keep track I think and not too fast. as long as it is on a private road.
520 + hp I suspect.

okay - finally got around to doing the test in my little old S4....
temp was 26degC, very uneven road, slightly uphill - not much.
cruising at 2040 revs, floored it, 9.59secs later I hit 6000rev exactly.
WOT from 2k revs, timing from 3040 to 6k revs = 6.87secs
max air flow = 267.28gps, max 462.8Nm torque

How does that compare..?

Did not fully understand your post I read it as you did it in 9.59 which is close to standard Rs4
If you did it in 6.87 then lightly to be awesome s4 and more likely to be an S4 turned into an rs4.
But great for you to put in the info.
At what revs did you measure the air flow and what calcs did you do to get the torque and how much power do you think you have?
If you did measure from a certain Rpm why that setting.

very nervously tried this on my little bendy b-road. 21.5 degrees and 7.6secs. So that's obviously slow in comparison.

I'll have another go when I know the road better. Think a motorway would be best!

flashyg - 9.59 was from 2k revs to 6k revs. ie. plodding along at 2k hitting the throttle and starting the stopwatch. The car is only stage1 revo + a few other bits but nothing serious. The only RS4 bits I have are DV's and ignition coils. air flow from memory was approx 5k revs and torque was about 3k - but all from memory. I have worked the power out to be approx 330bhp. But mind the gearing is different and whilst my car hits a brick wall at 6k revs, you guys are pulling faster and faster. I did both 2--> 6k and 3--> 6k as that was most representative.

The cars throws you back in every gear from low down revs and thats why I can't justify spending so much to change her for an RS4 just now.....the RS4 is the better car full stop, but I feel the power delivery on the S4 is much more useable. Day-to-day I rarely go above 4k revs in any gear, there is so much torque below 4k that I have no need to normally chnage from 6th and certainly no need to change below 4th for overtaking etc. Revving the pants off her does not make her go any faster.

I Loved my last s4.
With a few grand spent on your current car you could in the future get a lot more form it as I'm sure you will know.
Truth is we are all in similar boats and these are not at all easy cars, sorry ships to work on.

These cars are definitely not low maintenance. Professionals hate seeing my car coming in to the garage as they know they will have a difficult time working round the limited space. I went for the Rs hoping it would be more robust than the S4 and long term it would be a more stress free motor.

Not the case I will keep modding it I feel as it is inevitable parts will fail. I will up grade engine turbos and all the rest as other components fail and I am working in that place as a result.

I did always feel when I had the S4, If only that power could continue after 4.5k revs that is the main reason why I went for the Rs4. It is important to clarify some inconsistencies, when you compare a tuned S4 to a standard Rs4 of course the S4 will seem to have more torque low down as the tuning has a great impact on power, But when an Rs has the same tuning applied it will seem similar low down but the power will continue to come. This is extremely satisfying for a driver and I'm sure you will agree it would be great if you could get that from the S4. Any you can with mods..

Keep the logs coming I'm still not sure how your car did on the 3k to 6k mark TR was it 6.87 if so that is exceptionally fast. I don't think the gearing of 4th is much different from memory. It seems faster than mine at 7.5sec. O No! I think I need a chill pill.

Any other Rs's Or S's up for the challenge.
Steve you have proved your point 6.83sec.
It is good fun but don't forget not on the public roads.

I used VAGCOM logging group 3.
It was very difficult to get a clear run, and the road was a dual carriageway, slightly uphill and with a curve. So I need to find another road to do a proper test.

Nevertheless my timing was 12.92 seconds!!!

I'm concerned that my MAF only reached 250, whereas previously I recorded a peak of 280. Maybe something for AmD to look at when it's in for service soon.

Rob,
Are you sure you were in 4th gear?

Post by **tartan_rob** » Wed Jul 27, 2005 2:56 pm

Looking at your figures perhaps not. I'll try another run.

Post by **Dippy** » Thu Jul 28, 2005 1:27 pm

Rob,
Yes, I now realise there are 2 different threads. The RS4 test is 3K-6K in 4th. The FATS test on the S4 forum is 4200-6500 in 3rd.

Looking at the results for my FATS, my timing from 3040 to 6000 was 6.84secs, very close to yours.
This still worries me for the reasons above.

There is a problem here. The point of the discussion was to stick to a simple repeatable test. If you start to use you own version it really will not be of any use.
The test is simple 4th gear 3k to 6k
Start the rolling process from 2k and time it from 3 to 6
Best if we could have a few others try it.
No vag com required just a simple phone timer or stop watch.

Don't meant to be annoying simply light hearted, but so far the results are:

Flashyg 7.5 rs4 stage 3, 470ish timed 3k to 6k in 4th gear starting at 2k

Bakerdcb 7.52 rs4 stage 1, 420ish timed 3k to 6k in 4th gear starting at 2k

Stevesmee 6.83 rs4 stage 3, 520 ish timed 3k to 6k in 4th gear starting at 2k (+fmic and blue printed TB's)

Tartan Rob 6.87 ,s4 revo stage 1, 330ish timed 3k to 6k in 4th or 3rd gear starting at 2k
(fastest s4 this side of the silver bullet! if it was 4th gear)
awaiting absolute confirmation from TR as to which gear.

Dippy 6.84 s4 ,full miltec Stage 2, Amd chipped 350ish timed 3.04k to 6k in 3rd gear starting at 2k.

The 3 rd gear runs do provide information, but it would be best for us to do the comparisons in the same gear. 4th from 3-6k
so tonight's home work will be"Any more for any more"
And s4's can you do your home work again.
Its only a bit of fun hope you are well guys.

You mean floor it at 2k in fourth and then time from 3k-6k Gordon ??

Post by **tartan_rob** » Fri Jul 29, 2005 9:22 am

Okay - now that I've had you RS4 guys pondering....I did quick manual check last night and my run was in 3rd.

Post by **flashyg** » Fri Jul 29, 2005 10:19 am

Yes Dave,
that's the one. Be kind my friend. I don't know if it want to know if it is really fast as I'm sure it will be and Ill wish I bought a red one .Why did I start this thread! Any I got a Lambda sensor error so that can now be my new excuse.
