Thanks, I try to be a nice guy lol.
Tis very true about working on it…
Then when I remind you that this is bunk, you rally back with this
[quote]lol you are kidding right? I’m talking simple math here.
2.2 60’ minus 1.8 60’ is 0.4 seconds… 11.7 - 0.4 = 11.3
2.2 60’ minus 1.6 60’ is 0.6 seconds… 11.7 - 0.6 = 11.1

So if it’s simple math…were you suddenly shit at math 2 hrs ago when you said it was easy 10s? Make up your mind.
I told you up above that the whole ‘woulda coulda shoulda’ numbers you were throwing around are bullshit, and I asked who told you it. Then at the end I said the 1 = 2 thing is bullshit on an AWD Audi.
I’m not sure how long you’ve been running 1/4 mile lists for AWD Audis, but for me it has been about 4 years. In person I have maed around 200 passes in my Audis. I have also watched another 2000 passes by AWD Audis ranging from stock A4s to balls to the wall stage 3 B5 S4s and supercharged B7 RS4s. I guess you could argue with me or question me for something to do, but I’m just trying to help you get pointed in the right fucking direction and to ignore a lot of the niose that is holding you back. You instead want to be right and be defensive. Fine by me. Now we know you don’t want to be helped, you just want someone to pat you on the back and say way to go. So…way to go.

If there was such a thing as a fantasy 1/4 mile league of Audis I’d have no doubts you’d be the winner every year.
If I wanted advice on how to get my car in the 10s, I’d probably talk to someone who can tune a car and has been involved in fast builds and cars. There’s many here. Sak, I’m not trying to argue, but is your advice “dump the clutch at 6000 rpm”?
I think he should just run with a 2 step and antilag, and forget about the handbrake loading. These aren’t K04s, obviously his turbo can’t spool under 4000 (5000?) so it will always be difficult without other tools.
british, Not sure exactly where in PA you are but if you want to road trip and come to Thompson I’ll meet you out there… Supposed to race another B8 S4 on either Sat. Oct. 12th or 19th… I’ll be out every Sat. in Oct/Nov weather permitting… Looking forward to seeing you improve your times… I think the car has a lot more in it with a better launch… Thomspon hooks fairly well ;D
It’s funny, you talk shit about me giving him advice, and that he shouldn’t listen to me, he should instead listen to someone who has been involved in fast builds and cars. Then you proceed to give him loads of advice. So why should he listen to you? Because you put a tune and pulley and race gas in your b8? because you borrowed your dad’s ferrari to run low 12s? because you have a garage full of busted cars that don’t run? What qualifies you, under your system where people aren’t allowed to help BT?
I pointed him AWAY from the morons on audizine who are feeding him bad advice, and pointed him TO the video Jason from JHM put out 5 years ago to help B5 guys like BT launch their cars. Jason back then went 11.1 @ 129. He has since gone 10.8 @ 130. Does he qualify?
read the photos post I made above jspazz and you might not be so argumentative. BT didn’t launch at 4500. He simply launched in the low 3000s and bogged the fuck out of it. Everyone wants to believe there’s a conspiracy and that something is wrong with the car, but he just fucked up. Simple. Watch the video inside. Watch the video outside. He’s nowhere near boost, so he’s going to launch like a stock 2.8 A4 since that’s basically what power he has at those RPMs. If he insists on launching at super low boost, at least slip the clutch and slide out rather than dropping the clutch and bogging like mad. So far I’m the only one to tell him the hard truth.
If I were him, I would do EXACTLY what I showed him in the JHM video I posted when he launches his car. That video was made by the guy who is universally regarded as the best driver in the B5 S4 world. I would also stop making silly ‘woulda coulda shoulda’ comments. it’s almost reading like ‘hey I built a great car, so since I trapped XXX I am going to put myself down for a 10’. That’s what the EPL tuned guys with giant Tials used to do.
Hey BT, what you’re using is the “standard” 2 step and antilag available, then, not the “rev limiter” solution?
IIRC it’s a ignition spark cut to hold RPM, and not a retarded ignition 100% throttle scenario…
Why practice launches without it? What sort of pressure are you seeing with it, about 15 psig?
You can say what you want but the logs clearly show rpms were RISING until the ECU cut the throttle, then the rpms dropped down to about 3000 until the throttle went back up to 100% from the ecu.
That’s the only part I disagree with you on.
I can label the ecu log if it helps.
That’s a 4 hr trip for me… I’m in Central PA, State College area.
Correct, it cuts spark and retards timing.
I’m hoping to get a good enough launch to not need the launch control as it is very hard on turbos…
OK here is my analysis from the launch data from the 11.7 run
It clearly shows the rpms were rising after movement occurred (movement did occur at the rpm saki said) bhut that the bog in rpms was caused by the throttle being cut.
Do you agree with my analysis saki?
I have a theory about what caused the throttle cut, I will test it on my way home and let you know.

Gotcha… Sorry, thought you were closer to Pitt. Either way good luck with the car!
[quote=“primetime”]
Thanks!
Lol maybe your clutch switch is sticky or misaligned and at 5000 rpm your anti lag kicked in
Well the tune actually had both the antilag style launch control, plus the “throttle cut no boost building” style in there as well…
Now the antilag system was set lower than the throttle system, so it should never have activated.
But I removed the throttle based system from the tune, I will test it that way tonight and see if I can replicate the problem.
My 3rd (and last) run of the day I did launch at 5000rpm.
The problem with it was that I spun all through 1st gear due to no traction at the track that day… then bogged going into 2nd because the speed wasn’t there.

BT, really I’d say spend the time trying to get all the tricks dialed in, there’s a lot going on and it all happens fast n furious with little or no time to react once the motor on the boil. At the very least the 2-step/antilag launch is a measure of consistency. IIRC it is ignition cut, no? Not full fuel flow, so is it really hard on the turbo (are you firing flames lol)
Looks like it spools really slow at first then between 5000 and 6000 the IM pressure basically doubles, must be fucking violent, based on the last log you sent. but still you are losing spool between shifts. Wasn’t, for some people, the antilag/flat shift also tripping the knock sensor between shifts and retarding heavily?
Can you post the log for the run, with ignition? I’m just curious.
Or just launch like that video, maybe that’s the method. Don’t forget to turn off ESP lol.
Actually I don’t have any good logs from the track as the laptop kept stopping logging at the top of 1st gear lol.
Need to check it’s anti vibration settings.
I can post some street log data though.
Please stop saying “Lol”.
Grown men don’t go around saying lol all damn day.
If your goal is to break records with your car, please do it and stop trying to get into the book of world records for saying lol in every damn post you make.
Thank you and please continue your forward advancements with your car.
LOL!
LOL WTF FAW, smh
Damn you pt beat me to it
FAW is on to something though. I’ve noticed that over the past year. Virtually every single post BT has ever made has lol in it.
