is is true about some damper in the hydraulic clutch line?

A5/S5/RS5
#1

2012 S5 4.2 6mt sport diff-
I have 15k on my car and decide to head out to sears point/infineon/sonoma raceway/whatever they wanna sell out to this week.

practice pass #1:
headwind pushed me back out of staging and red lighted me=no ET

practice pass #2. I stage quickly, set electric parking brake, disable traction control and depress the throttle, knowing that the car hold revs just under 4k. ugh, except when electric parking brake is on. so as the lights are cascading downward and lower the revs by ear…and dunno what rpm I launched at, but seeing the tach fly to the redline wasn’t expected when assuming launch rpm limiter would be on.
2.05 60’
5.81 330’
8.891 660’
11.512 1000’
13.738 et @101.36mph

practice pass#3
I forgot to turn off traction control.-yeah, I’m slow in the head!
apply electric parking brake
launch at 3k-learning the car…
it bogs, ugh!
2.315 60’
6.103 330’
9.180 660’
11.797 1000’
14.013 E.T. @101.82
mph is there, just not capturing it

practice run#4
traction control disabled
stage quickly, apply parking brake
set revs to 4k and launch- tires light up for a brief moment-
after engaging second gear, the revs slip up to 6k for a little over a second, then drop down and I realize the clutch wasn’t holding. don’t ask, I do know to remove my foot from the clutch, ok.
2.082 60’
5.864 330’
8.96 660’
11.595 1000’
13.827 @ 101.16 mph
capturing the car’s potential a little better, but know what i have to do. lower rpm on launch

round 1 of elimination
I noticed the headwind died down, so I changed my dial in from 13.7 to a 13.65
stage quickly, set parking brake, brought revs to 3500rpm and launched-no bog, tires didn’t light up, had a touch of the good wheel hop that my old buick used to have when the launch was ideal.
1.966 60’
5.643 330’
8.684 660’
11.27 1000’
13.491 et @100.15 broke out by a bunch
I dabbed the brakes because I had my guy beat, but I’m still learning my car’s laugh delay and so I was cutting horrid reaction times which you can’t do if you want to continue into the rounds of elimination. my guess is that my mph would have been a touch higher, but the smell of my roasted clucth after the last two runs will prevent me from going back out there until I figure out why my clutch is slipping from the first to second gear transition, as in it won’t hold second upon fast clutch pedal engagement. again, I know what I’m going and I’m not speed shifting!!!
I’ve rearched the forums and some people are blaming a delay valve that is conducive to super plush clutch engagement, but needs to be removed if I want to drag race.

to me, past experience has brought slipping clutch issues in final gear-as in 4th on a four speed trans, or fifth on a 5 speed. those gears have the highest resistance against the engines.

any insight, even from “pinkberry” ?

Haha

Sounds like it was fun. What’s done to your car?

Is that a permanent dragstrip or is it on the back straight or something? I didn’t know it was there

Advice would be to keep doing what you’re doing. Also eliminate a few variables like cooling the car down, going to test and tune vs bracket racing (so you can focus on et) and finally, if you can, go to sacraments raceway with the jhm guys when they test their in house s5 next. I think it’s a good track as it’s at sea level and gets cool there.

What was the da when you went? Also want me to add you to the database? If so post up slips etc

With respect to the clutch the Audi clutch slip tends to happen in low gears when the car is providing resistance (inertia, 4000 lbs and add traction). To see if it’s healthy go to sixth at 30 mph and floor it, looking for spikes in rpm.

The s5 clutch just isn’t that good. It gets heated up and unhappy very quickly it seems so you need to baby it. Launch a couple of passes , then let it cool down for a while. That’s why bracket racing may not be ideal because you make passes on someone else’s agenda.

#3

So true, when this happens i just stop pushing the clutch and let it rest. So far i have had no issues, but i the near future I will be getting JHMs stage4/5 clutch upgrade

#4

Its hard to get good dats on the s5 I was thinking about getting one a few momths back. The 13.5 seems about right. Really the s5 is s4 power with just a lighter car.

If saki says the s5 clutch is no good then that would explain it. I dont know if there woild be a damper that maes no sence as they dont have it in other cars…if it was in the new b8 s4 then i would ssy you might have one…Also deff take sakis suggestion get with thr jhm guys if your local. Even if you do nothing to your car they would be good to know. If you do mod your car rhen they are the best to know.

Nice to see some s5 track data

#5

If it is any consolation, jaybequick@JHM roasted the clutch on their S5 shop car after installing their shifter, doing a carbon clean, and installing their intake manifold spacers. It apparently was replaced recently at some point too.

http://www.audizine.com/forum/showthread.php/549681-JHM-just-acquired-a-2008-S5-V8-6-speed-MT-for-more-R-amp-D-and-track-abuse-(build-thread)?p=8977590&viewfull=1#post8977590

#6

Oh some updates. So jay is driving the s5 daily. Cool.

That’s great news for the s5.

#7

But if the S5 does indeed have a one way flow restrictor that does slows engagement of the clutch. Then every clutch upgrade is still subject to this delayed engagement. I looked at a parts list for a 2011 S5 and illustration for the hydraulics do have something between the clutch master and the fluid line heading down to the clutch slave cyl. I’ll research this guys because I don’t wish to destroy my clutch and I am willing to eliminate that delay valve.

#8

I know that BMW uses/used a valve like what you mentioned but I don’t think that Audi does.

#9

Saki, I can’t keep doing what I’m doing because it is destroying my clutch and possibly creating hard spots on the flywheel. car does not slip in sixth. so I do believe it is a flow restrictor causing the slipping. I think USPmotorsports has someone there that is aware of it and has an elimination kit for this possible restrictor.

I can race at Sacramento, but the emperical data you need isn’t to be found at that track. any MPH and elapsed time is mysteriously fast-Those that race, know about it. I wouldn’t post anytimes on your list from that track. I know you want proof so either I’ll head over there after I fix my clutch issues, and then to my local track, Sonoma Raceway/sears point. to have you get an idea. I asked a customer that travels to race super gas class all over the Western U.S… he explained it to me. I first asked him how my turbo charged could drive a personal best in 95 degree air temp. My buick drove 13.46 @ 103. Car should launch well on a hot day-traction/track temp, but a turbo charged car doesn’t like hot ambient air temp. I’ve raced, almost weekly, for three years at Sonoma raceway/sears point, and I never was quicker than a 13.7 and NEVER made 100MPH until it was below 60 degrees. track altitude of sears point is 13 feet. My customer said that my results are them same for everyone. Perhaps have the JHM peeps head down to bakersfield sometime and get a differing time

sears point is a permanent strip. evenings usually includes a headwind in the evenings and after 7:00pm, the headwind might die off and faster times begin. If you race there enough, you know to contantly stare at the flag and watch for fog forming on the hills.

what have I done to the car: AWE touring exhaust, bilstien shocks which won’t launch the car as well as softer OEM shocks, alu kruez plate and the eurocode sways and links. and three cans of seafoam in the intake about every 5k to try to prevent the carbon build up. california 91 octane pump gas

Sorry, I had my wife recycle the timelslips from my run, but I’ll email the track because I know that I raced street class and was #81. I’ll try to get them, but my quickest run had me tapping brakes to prevent what happened anyway, breakout. so I left ET and MPH on the table, but like you wrote, it’s bracket racing not a test-n-tune

Saki, Sacramento get shotter that Sears point/sonoma raceway. Sac is in the central valley, east side = most most. Sonoma/sears point is about 1/2 mile from the San Francisco bay. Temps are regulated by the bay. Sacramento has small rocks/pebbles all over the place. so when cars lauch, and the staging lanes are right behind the strip, I would stand next to my car talking and catcha glimpse of something flying by. These glimpses are stones flying by my head and car. you need a giant blanket to protect your paint job. stones aren’t that great for a RWD vehicle to gain a good 60’ time and the sound in the wheel well sounds like you just drove over a gravel road. soft rubber and stones-not good.

Saki, you want more details about SAC, PM me.

[quote=“JimmyBones,post:8,topic:4545”]
I know that BMW uses/used a valve like what you mentioned but I don’t think that Audi does.

EKTA revision 7 Audi revision 7.3 including update 895 show a part #16 that is on the clutch master end of the hydraulic hose leading to the slave. there is no part#, so I would assume it is included with the hose.

there has been some chatter on other forums about it. but no definitive info. I’ll find out.

#11

Ahahahahahahaha hhaha

Rirst rule of bullshitters is when they want to give you proof privately…sure spoke wink wink…yha I recycled my time slips too…all of what you said is just shady…you dont have a camera on your phone to take a picture before you recycled them…

Hate to kick you but jhm and several other cally guys have proven you wrong…by doing just what you said.maybe you have just accepted some odd local myth as truth…as fsft wise sac inifan sears all have produced similar times for guys in the past.

Dam just when I thought we had more good S5 owners…its crazy

For those of you excluding spoke that dont know
Certified tracks get tbe words certified because they have the system certified…for nhra rules and times…if there is any events there they need to pass spec…

Some tracks are faster people say due to it being a better track. Smoother surface better transitions better altitude etc etc.

#12

first rule of bullshitters, sheesh! here we go, on the internet: please read this article and get to the second page as if it pertained to me, at the track with an Audi S5.
http://www.pressdemocrat.com/article/20130810/lifestyle/130809501
Then let me rebutt about the Sac track. yeah it’s certified… doens’t it can’t be adjusted.
If you read the first article , then read this:
http://www.marinij.com/motorsports/ci_23750390/motor-sports-novatos-beckstrom-wins-nhra-super-gas
the fella R.B. talked about, George N., he worked for me until his stroke. Now this guy has cancer… wait troll, the Redline oil sponsored local racers for super gas/super comp are aware of it. if you want to pm me, I’ll forward emails about George’s cancer, hospice and rehab from his stroke, written by his wife. then you can call her, because it’s VERY important to you to prove that I’m a liar, then you’ll be the google merit patch for your due dilligence.

Then you can call the reporter from the pressdemocrat and ask her how my interview went. ask her about what I teased her about, writing an article in absentia because she wasn’t theee, then get the name of the photographer and contact him about how he got my work phone number for the reporter, they didn’t use my photo. ask him what type of piece of paper I wrote on. ask him to turn the piece of paper over and verify the #81 on the frickin timeslip, that had no time because I’ve never dragged draced a manual trans and forgot about getting blown out of stage.

Tell you what, I’ve emailed the track so you can verify that I raced street category under #81

Chris, I don’t doubt that many are less than honest, but no need to just slam me. I hope I do get the time slips form the track, and I will ask for a formal apology form you, and I won’t expect it either. welcome to the internet-

Chris, I’ve probably made more passes in my Buick Grand National than you have in your life. I even one a weekend norcal event with division 7 points. raced ringers and beat a sand bagger that I pushed him to break out. Here’s the best part, and I have nothing to provide you as proof, but maybe you can waste your time and call the good guys in peasonton to look my name up from waaaaay back like 1992-95.
anyway, I had a 13.91 dial in on my window, but since I didn’t want to break out, I removed the number 1, and had left a 13.9 dial in. I then got the offer to split the winnings with the guy from the hayward drag club, you wouldn’t understand since it’s a common drag race proposal, I declined so I could pay for the helmet I just purchased and had been eat ramen noodles all wee because I was poor. I beat the guy, he broke out and I ran a 13.911 on a 13.91 dial in.
I know how to race, and sleep well knowing that I don’t need to prove sh*t to you. but I will get the time slips for saki, for his data. it’s not even usefull since I tapped brakes and nosed over the front so I wouldn’t break out, and I still did miseably because I’s still learning the car. time and ET was left on the table. Saki was right about a tune day, but the track is 10 miles from my house, even closer to my business.
Saki- I’ll try to get the slip reprinted.

#13

race at Sac, then get back to me. track isn’t ideal. I thought it may have been slightly downhill, but I was informed otherwise.
Chrisk, how does an 87 Buick Grand National that runs 13.7 @99.9 mph in cold weather and 13.9@ 97. mph in hot weather-like 80 degrees or warmer at sears point, do a 13.4 @103 mph in sac on a 95 degree summer day? remember I raced for three years with the same car, I know it better than you do. I also know that I’m the idiot that staged my buick at sac and the guy running the tree just stared at me…then walked up to me car and closed my hood for me. Like amateur hour for him. I was sooo embarassed, but I remember.
factor density altitude, and the fact that turbo charged cars, even intercooled ones, don’t like hot weather as much as naturally aspirated engines. Then factor that on hot days for RWD turbo charged cars, that you can launch with a little more boost/rpm, and will have a better 60’ time, but at the trap speed, the mph would be less. so how could it happen, and I’ve raced at bakersfield too with the division 7 boys, and never broke 100 mph. Chris, it’s easier to make friends, even virtual friends on the internet, if you are nicer to people.

#14

what a fucking waste of time. Who cares about some random ass whole getting cancer and some article. You want to over case FACTS with some random babble. Becase all you do is talk. Here is something. I owned a GNX for 15 years raced it for about 10 stright in heads up 10.5 tire class. So there is one more you got wrong Then I have raced my LS1 for about 20 years here soon. So your Bullshit talk on how you race is better saved for some 15 year old not someone well past that.

sorry you don’t know how tracks work and how the time system works. Sorry you don’t know how to prep a car sorry you also have an apparent emotional issue with this. Till you diss prove the people who already proved you wrong then your just wrong. Then till you diss prove what we already know…and thats the track and its equiptment is CERTIFIED to be accurate then your just one more guy that should own a B5 making excuses…

How can a car run faster on a hotter day.
1 it hooks better
2 the Da might be better
3 The berimiteric pressure is different
4 the track is a better track with no bumps transitions.
5 the track has an incline that helps the turbo boost bettter.
6 the track has no head wind or has a good location and has a tail wind.
7 you get more passes and the car runs cooler.
8 the car has a better tune when its hotter out. On older cars you needed to do more for tuning for the elements.
9 the track is prepped better… fuck man get a clue this can go on for ever
There is about 1000 more things.

You can make for better internet friends when your not full of shit and make emotionl facts rather then rational facts.

first your dog ate your time slips you can’t disprove the Certified facts and you also can’t dissprove the fact that people other then you have raced at all three tracks in CA and have seen the same times. Your about 5 years and 10 debates late for this argument.

If you were a real racer you would already have known this. Seems you talk more then you actually know. Each track has its good points and bad. Some tracks have better burn out boxes some have better transitions. If you didn’t know some tracks actually prep the track. Since you seem to not know the basics let me help you. Some tracks put down a sticky fluid that will help your car not spin also tracks will put this down past the 60 foot mark.

dude your long ass post and weak understnading is just as bad as your recycled time slip… PM people the secrets to your conversation

#15

http://www.racesonoma.com/documents/wnd-results-aug7.pdf

scroll down to round one street where I got my ass handed to me in the first round for cutting a horrid light and breaking out huge. happy now?

I think my experiences at my local tracks and the customer that I have that races Super gas/super comp know have an intimate level of experience that you and I bot DON’T have.

I know about treating a track, altering tire pressure but do not own a a kestrel 4250, but do know hot to adjust throttle stops.

#16

Funny thread is funny.

I have seen pbox data from sacramento. It’s not short. It’s not straight downhill. It’s just a typical nhra track that happens to be in the ocean with awesome da.

Same goes for pbir . It’s another track where everyone has good results. However we have seen pbox data there as well, and all is well.

Fact is jhm has run good times at sac but many of their times and traps have been beaten Or matched by customers around the country. Like at englishtown. Or Cayuga. Or carolina. Or pbir.

#17

Good to know about JHM results duplicated at other tracks. That is solid enough credibility for me.

When I used to race against those gmc syclones, they would fly out of the hole with a super quick 1/8 mile but finish with a trap speed of 93 mph…crazy torque

and about chrisk, what’s his story? why does he have to slam me? my dog didn’t eat my timeslips, they were really recycled. I do have a cat, but we’ll avoid the cat A5/S5 thing. Cat did steal my porkchop two weeks ago and growled at me when I took it back. but those weren’t time slips. I’ve emailed the track asking for them

and if you want to see Chrisk’s stable, it’s here

http://www.flickr.com/photos/chriskober/page1/…and that’s a Grand National folks, not a GNX.
Perhaps chrisk sold the gnx and also had or purchased a grand national but…if it isn’t
Gnx had added on fender flares, which Chrisk’s car does not
Gnx has A GNX emblem on the front grill and rear deck, Chrisk’s has a GN logo on the rear deck, not the GNX . I had extras because I was gonna do that stupid gold plating…remember when that was popular? but I didn’t
GNX has a special diff cover made of aluminum and reads GNX and it was glued on with permatex anerobic sealer at ASC, which Chrisk’s GNX does not.
Gnx has a torque arm bolted to the diff, I don’t see it on Chrisk’s diff having the attatchment, but perhaps he upgrades away from the 8" ring gear 10 bolt diff?
GNX had a set of killer looking gills on the front fender behind the wheel well, Chisk’s does not.
GNX had no emblems on the fender, but you can see grand national emblems indicating this is a GN
Gnx and this GN in 87, were both intercooled. chrisk’s gnx, that looks like a GN with some 16" gnx rims, both have the 87 blacked out grill. 86 gn grill had chrome trim-horizontal piece on the top of a blacked out grill.
chrisk’s gn, gnx has an aftermarket intercooler in front of the radiator and he has eliminated the factory garret air research intercooler, or the prototype one that garret made for the 547 GNX’s that were sold.
Chrisk most likely has a 4.1 V6 block stroked and has had parts from applied technologies and Ken Dutwieller, I’m not going to google ken’s name to see if I spelled it correctly. Chrisk’ may have swapped out the TH2004R trans that could not hold up under an 11 second GN, or in this case, a GNX.
OE turbo on the GN was a T3, and the GNX was the same but with a ceramic impelar. Chrisk most likely has a larger turbo A/R to accomadate the fatser times and a high stall converter otherwise why waste your time, right? If you want some advice, unsolicted advice, and you are still running drum brakes on the rear, get the non-power brake wheel cylinders with the 7/8" bore size, it will allow for a little more boost at launch
If that car in that garage, and it looks fun and fast, it’s not a gnx, no different that purchasing a RS5 front and for my S5. I don’t do that. nor would I mod out a real GNX, it’s worth too much stock, and any smart person would do what you have done, get a GN and modify it. My GN was owner by Reggie Jackson, Mr October. looks like you have a turbo TA, 89 vintage, pace car to the indy that year and made only 1500 of them. to fit the engine under the hood, the 3.8 heads were replaced by 3.0 buick heads. roller rocker valve train, where are the syclone and the typhoon in your garage picks, two of the worst vehicles to bracket race with in the world, liquid intercoolers with fluctuating elapsed times as high as four tenths…sheesh!
if that GN is supposed to be a GNX, then that is the other “fake” thing on that photostream.

Chrisk , I’m sure you’re a great guy in public, just like I think that if you and I ever met, we’d probably like each other. and your taste in cars…I really like. I miss my gn and seeing the pics of yours reminds me of a fun car. and the speeding tickets and blazing the tires through three gears in the waldo tunnel and filling the tunnel full of smoke…

Chrisk, my auto shop in high school had an 85 regal with 87 gn/t-type/turbo regal components with it. the mass air flow sensor has hand scribed part numbers along with all of the other parts on the electronics. it had no vin on the dash. no posi either. they got it because a local vo-tech in novato had a teacher, Bob White, that used to be a engineer for GM back in the day. that high school car got me hooked on that type of car.
oh, chrisk, if you don’t have that x brace, aftermarket installed behind the rear seat, get it before you get “the crack” that most g body cars get above that little side rear pillar window on the steel. almost all get it, especially if the car goes as quickly as your does, it may have already occured with the amount of runs you have on the car. kenne belle or kirbans or eastern performance had it, I forget…

#18

Lol wrong Chris K

You’re failing

spojke say something like a I feel statment then have a sting of events that make no sence like you recyleed your time slips and can’t prove anything from sac being a fast track or that you even went to the track is just crazy.

Try readying below…

in the future try not being such a huge fail…and as saki noted try again not my car… I love how now 3 times you have just made up shit and thought thats what what…the best part is you bable on and on abott it. spookie and funny all at the same time.

so your rebuttle to my facts are a 10 paragraph post about GM products. Its good to see you have some idea on some cars. Maybe tracks are not your thing then.

#20

I’m sorry for depesperately attempting to discredit you for dismissing my visit to the tracks. I generally don’t save time slips in a binder, or spray ice water in an intake manifold betwwen runs, or ice down an intake box. I never did, even when I USED to Race 15 years ago. yeah, I’m rusty, as anyone would be.
I’m working on acquiring timeslips, I’ve emailed the Sonoma raceway.
you want FACTS:
http://www.racesonoma.com/documents/wnd-results-aug7.pdf
yeah, it’s recycled, your words, but it is FACT and independant of any timeslip which could be from ANY race car. whoever wishes to veify it can by looking at my memebr info form months ago when I joined this forum.
http://www.pressdemocrat.com/article/20130810/lifestyle/130809501
independant article written by someone who interviewed me for competing on the evening that I have been discredited from.

The submitted information on this can be matched up to the time slip data, when I had possession of my timeslips, of my elimination run

until I have timeslips, that match up to street class entrant #81, emailed to me by the track, this INDEPENDANT information stands on it’s own merit.

again, I apologize to attempting to trounce you. I’ll try, in the future, to ignore insults from trolling and not step it up in the future.
