My cars performance last night

B8 S4
#1

First off, was cool seeing a lot of the forum members on here last night. Wish I could’ve hung around a bit longer but my brother was not feeling well. All cool guys though with some sweet audis. Hope we can do something like that again!

My car…

Beat my previous best of 11.9 @ 114. I ran a few 11.8 @ 116’s. Happy that the car is moving faster but still not where I want it because I have the recipe for a better time. Consistently trapping 116/115 which is better than my previous 114’s, but still not where it should be. I’m looking forward to figuring this out before the season ends, I will get new logs to help with this

Unfortunately my darn ross tech will not update its firmware so I couldn’t log. Sucks because I really want to see where the car is falling of.

I do have my own idea on where the car is lacking though. 1-2 shift was money all night but every shift there after, I heard the clutch slipping on upshift. Not so pronounced as Ron’s 4-5 shift, but from in the car I can tell that was one factor slowing me down. The lower traps I can’t quite figure out though… I’m guessing sakimano might not agree here but I think the dsg tune is needed for a little more trap speed and to get seamless shifts at this power level. The car just was not shifting perfectly all night, with the exception of 1-2 surprisingly.

Also the car feels like it’s bleeding boost in 3rd gear, it felt like it was backing off in 3rd and then pulled much harder in 4th again… This is speculation and I’m going off what I felt last night after sleeping on it… I’m going to try and get back out to Lapeer tomorrow to log passes

Anyways, DA I think was around 150… ~52F, 36F/32R in tires

Made all my passes with Mike (drob23). I am the “winner” on these slips

madman4you managed to take a video last night:

The car spun through 1st and part of second on this one! Both Mike and I could not hook on this one

I can’t understand why cars that et almost half a second slower are getting the same traps or extremely close.

Does…not…compute

#3

If you’re talking about his vs my car…I really think it has something to do with the TCU “amax” mode APR is running. Likewise how I’m able to launch at 4k and waste a lot of time getting out of the box spinning, but then when I hook, the engine is far into the power band? Can’t explain it either. I do know that the timing system can show slow traps, including that 97 mph monster I put down :smiley:

#4

Matt was having the same issues, I think, with the LC. 11.71 best I think?

And he was getting tons of bypass. 10-15%. weird. After mild knock for a second on throttle tip-in, zero knock down the track on the spray /91 gas, on either 100 or 104 tune.

I’m a total believer in the spray now.

#5

I have a bunch of vids. Let me know if I’m ok to post them.

#6

Yes please do. That would be awesome

#7

I’m equally puzzled man. Hoping to make it to lapeer tomorrow to log some passes

ET is determined primarily by the front of the track.
Mph is determined primarily by the back of the track.

If your car shoots out of the hole and everything is nice, but it steps in to protect the car towards the end of the track, it can wreck your MPH but your et will be pretty close to what it would have been.

I. E. There was one car there that ran 12.3@108 a couple of times and then 12.0-12.2@113-114. It was a conservative beta tune so the protection was pretty aggressive and stepped in because it was on3 of the first cracks at tuning the 3.0t, and the car was from 250 miles away so everyone wanted to start conservative. Ironically the chipdoesn’twork guys would call the tune aggressive because it was pulling timing to protect the car lol. Anyway.

The car was protecting itself so it pulled back on the reigns (probably pulled a bunch of timing) towards the second half of the track (which is basically 4th gear.)

When I looked at his 108 slips I told him that his 1/8 mph was on pace for 114. Sure enough the car trapped 114 a couple passes later. His 330’ times were on pace for 11.9 or so and he later hit 12.0

So it looks like his car’s corrections cost him about 1 to 3 tenths, but a whole 5-6 mph.

Generally we see these cars gain mph and cut et proportionately (tenth for an mph) so you can see how getting out of it, or the car pulling back in the second half won’t mess up your et as much as your mph.

#9

I can’t keep track of who is who

I didn’t even know the wrapped car was jones on this pass lol

Those are actually great vids, good stuff. Thanks for posting.

First vid is left Jeff vs right Glenn (madman4u - he is the one who melted the boost tap line and had a massive boost leak)

Second vid is left me vs right Muneeb (mrmomo)

#11

Glen blew his hose on that run right after it shifted into 2nd

#12

Muneeb, Good stuff bud… Glad to see you beat your best… I’m guessing the car was bypasing a decent chunk of boost which is what’s holding your mph back. However, given Jeff didn’t do as good as he usually does and w/o logs it’s tough to say. Would really like to see logs from your car given what the ones from S4mattys car looked like as he is bypassing boost all the time… My car doesn’t bypass nearly as much as his except the one morning I ran it on the street and IAT’s were in the teens… Just want to see as much data from the multi pulley cars and at this point there aren’t a ton of them… lol What fuel were you running?

Saki, Thanks for sharing the vids!

Mike, I know I’m sounding like a broken record but get rid of the LC and keep AMAX shifting…

B8.5 2013 APR Stg 2/APR TCU Passes at Milan
#13

Thanks for the videos saki!

Ron, thanks! I was running ms109 that night. Last time I drove the car prior to these runs was also to Milan and I ran ms109 then as well. I’m confident that was the only fuel in the car for these runs.

I will definitely have logs for you and everyone that is interested to review next sunday when I go to Milan again… I have to call ross-tech on monday to get my vcds issues sorted out. Conditions should be even better next sunday so I’m looking forward to it

I’m on the fence about which launch method is better for the facelift cars… Given what Sean@APR has been saying on Az, the facelift cars have some really good hardware in them for launching via LC. Our 2010/11’s have, and I quote “mediocre hardware” for launching lol… That is why mash and go is the better option on early cars. On the flipside, given the better hardware in the facelifts perhaps mash and go will work even better for them? Might be worth experimenting with Mike. I know how much you love going to apr dealers ;D

#14

no problem. I hate when people make vids and don’t show the clocks or at least announce the times so I do it religiously.

Here’s the RS7 against that ‘600 whp’ built 2.7T swapped into a B6 S4. You can take the 2.7T out of a B5, but you can’t take the B5 out of the 2.7T (owner). This was the 2.7T B6 guy’s best run of the night. 14.49 @ 97. Makes ‘600 whp’…traps double digits lol.

#15

Hahaha, saki is the B6 guy. I knew you told me your name but didn’t remember you mentioning your AR name. Good stuff. Yeah, my night sucked. That cheap lines was plugged in the way home and then replaced completely the next day. I went 11.74@118.46 today. DA was around 351ft based on my Dragtime app.

Saki good to meet you buddy. Thanks for bringing back my B6 memories.

#16

The B6 guy was me actually :grinning:

Good meeting you man, and everyone else for that matter, bunch of great guys.

#17

yeah, mdubz had the B6. I have an RS4 but didn’t bring it.

I was the really tall guy with the grey tuque on

Nice to meet you too man, that was one hell of a drive you made. Fun to talk with you before everyone got there. Hopefully you get the trans sorted and get ready for that roll cage you’re gonna need :smiley:

#19

Wow looks you like you guys had a bunch of fun! To bad I am on the other side of the country =[

#20

So nobody wants to say how Mdubz did with the built motor B6?

EDIT: nvmnd, found it in the other thread
