I have been thinking... S4 1/4 Times...
Stage 2 I was going sub 5 seconds. MTM claim 4.9. Don't think you'll see 12s at stage 2.

One word, Dissapointed!
Took my car to strip and while it was warm 27C, 81F the worst part was the rs4 gearbox which is just SLOW. I have to wait so the gear can engage when rpms drop. LWFW should help but I'm not going that way right now. My org. trans was much faster to shift, no resistance at all from 1st to 2nd.
Filled it with a mixture resulting 102 oct. boost 1.7bar to 1.5bar.
Ran three times (the line was 1hour long!) and the best (3rd) ET was only 12.57, 116.9mph or 188.1kmph, 60=2.054, 330=5.499, 660=8.286, no speed for this one, 1000=10.632
1st run et 12.68, trap 186.33
burned the fweck out of the ceramic clutch on my second run, a bit scary as it was supposed to be bullet proof. it happened when shifting from 1st to 2nd.
Launch is not my game. 2.05 best run bogged, others 2.002 bogged and 1.96 spinned.
Waiting for Kaygee to comment what means what.

Mmm, looking at my results I clearly loose too much on the launch cause I hold the revs too long. THis should not affect you though with the bigger turbos and power all the way through to redline!
27deg is high, and a 12.5 is respectable, your trap speed not bad - anyone comment on what the trap speed suggests the 1/4 should be?
Can anyone suggest a 1st 2nd & 3rd gear changes for a k03 car? I was holding towards 6k which is obv too much...

Hey Smurfbus, you need lessons in launching... 
Terminal velocity is v. good at 116, shows good bhp available. Race gas and 1.7bar we'd expect these kinds of TVs.
Expected ET is around 12 secs flat in a well launched S4 with that sort of terminal velocity. Your 2 sec 60' and 8.2s at 660 show this is where you are killing your times. However you know this already.
Only ever driven one RS4 so no real experience of their gearboxes. Doesn't sound very promising though. If it is a new boxs it may well loosen up and start to shift quicker with some miles on it.
Tell us how you launch and your shift points. We might be able to suggest some better figures. You might want to try a post in the RS4 forum as well. They might be able to help.
Which ceramic clutch you running?
In theory you should be sub 12 secs - 11.8 or so. Theory again says TV of 116 is around 470-480 Bhp depending on saloon/avant. Very nice.
Before you go beating yourself up, 12.6 ET is Dodge Viper GTS, Ferrari 575 and Audi RS6 territory so pretty damn quick.
P.S 2 sec 60' is tiptronic territory...

Trans was IIRC 28tkm driven. I bet syncros are worn ; )
I put motul gear 300 in there but it did not help.
First: ceramic clutch does not like feathering in terms of longevity, so I use sidestepping
First launch was 4000rpm sidestep, bugged
second was 4500rpm sidestep spinned and smoked front tires (strange as I have 1:4 torsen) . I also had wheelhop and clutch gave up on 1st to 2nd shift
third was 3500, bugged (I was trying to be easy on the clutch, VAST ceramic)
shiftpoint near 7000 as it really goes linear to the revlimiter. Next time I will try lower shiftpoint to see if it helps gear engagement.
Night before with this setup at 19C it ran 2.7 FATS so shifting and launch is definately killing my times.

Yep, 2.7 FATs is f. quick. Try reducing your front tyre pressures a couple of PSI or putting a couple more in the rear and trty 4250 launch. Best if you have a couple of spectators one each side watching the wheels. You don't need to do this at the track. Any peice of smooth tarmac will do. You want lowest lows revs possible without bogging the motor.
With that sort of power you might well look at 2nd gear as an alternative also. Will be harder to launch but if shifts are that slow eliminating a shift can only be a good thing.
Not running 19" wheels or anything silly? Also short shift first and second try 5K shifts as long as they drop you back into the torque curve this may well help the box shift quicker as well.

2.7 fook me! here I am running mid 5s *sigh*. I will be trying short shifts when I get a chance, I have over a second to knock off my launch!

thanks for the pointers.
I run superleggeras 18in 235-40.
That 2.7 is eq. about 3.1 S4 fats as in 58-91mph in third.
I will definately try shortshifting next time to speed up shifting.
How should the 2nd gear start be done if I ever have balls to try it. It will bog even easier and high rpms might burn the clutch? Even if it bogs it might be faster anyway? I might try it from a busstop sometime before going to stickier strip. I saw from my LM-1 that 3rd to 4th is actually very decent. I would think that 2nd to 3rd would get better with practice too.

Ola - Use vagcom(new version has 1/4 mile tests) to log some launches to see what times and the shift times you are getting with different techniques. Good trap speeds.

DOH, thanks. I already forgot that I have beta version in use so I will use that to find out the best method. I've lost my AP22 serial cable so I cant use it to download anymore.
2,66 fats a moment ago 19C , worst 2.8sec. added some timing although CFs are now max 9.5 but I had to try if timing would get better and it did but this is with 103oct

Smurf,
Thats a very quick FATS time.
2nd gear launch wont help 60' ft time, however it might well help 660' time and you don't need to do 1-2 shift. It is also less likely to spin the wheels in 2nd due to the higher ratio and it might be easier on your driveline.
It'll launch slower but hopefully because you drop a shift you'll make more time back by the time you are at the end of second. As you say only 2nd to third shift to do and then third to fourth which isn't a problem anyway. Look at your 660' times and compare to the drag strip ones.
It maybe that the quickest way is to use first just to get it rolling and then grab second before giving it too much power.
A few 1/8 mile runs with VAGcom logging will show you your best technique. 1/8-1/4 mile is already fast as shown by your terminal speeds. Once you crack 0-660' your times will drop fast.

Last night I tried a couple of launches before posting but it's freaking difficult. EDL kicks in (disconnected the abs harnes at the strip) and then one time 1st to 2nd clutch slipped again when the shift was decent at lower rpms. I bet it was pretty warmed up in the middle of my FATS testing. I think I'll have to lower my peak boost from 1.7bar to 1.6 or 1.5bar.
Its hard to find a deserted airport to practice too!
