A bunch of us went to the drag strip today.

[PutTogether]

Several Audizine members met up for a small Audi Mission Viejo event at the Auto Club Speedway in Fontana. We had just under a dozen Audi's, with three different B8 S4s making a showing.

I'll let everyone else chime in with their numbers, I don't want to spoil the fun.

I did, in a word, horribly. I 'feel asleep at the tree' more than once, having not been drag racing at a track in about a decade. Still though, I had a lot of fun.

Two things I learned:

1) LC does indeed directly lead to better 60' times. Four runs with, all 60ft in 1.9ish. Two runs without, both 2.1.

2)At least in 100 degree heat, ECU and exhaust doesn't make a car much faster than stock in 1320 ft. Brian and I both got our cars within two weeks, both 2012 DSG DSG, both the same amount of gas in the tank (just over 1/4).

I have ZERO idea if I did this 'DA' calculation correctly. I went to a weather site and got barometric pressure, temp, humidity, and elevation for the track today. No clue if the calculation for DA is correct, but according to the site I found, DA was 5612 ft.

My best pass was 13.38 @ 103.77. Stasis ECU / Stasis exhaust, with launch control.

Real poor video of a 13.576 pass. (we'll have better video along in a moment)

What the heck...were you racing a Ford Bronco?? [:d]

[Wah]

^lol

Strange numbers ... with an ECU tune [exhaust and LC], there shouldn't be a reason why 12 s isn't attainable.

Cutlass Wagon. Wagon that ran mid to low elevens all day to be exact.

OK, now I don't feel so bad. On Friday I did a bunch of mid-13s, the best being:

stock 2010 DSG
[email protected]
DA of 2400 (Cayuga at 10pm)
2.0x sec on 60' (consistent on all passes)
ESP/ADR off

The motor, and maybe DSG was heat-soaked from running 20+ track laps just before the strip, and found that leaving the hood open and shutting the motor down as much as possible in the staging lanes made a difference (first run was a 13.9@100 ...with same 2.0 sec 60' time). The 1-2 shift was always weird/slow on the strip, like 1/2 a second for DSG to shift. Tried a couple backroad launches driving home afterwards, 1-2 shift worked fine; my gut says it was a heat issue.

So are we doing this again in Oct/Nov? =)

I certainly hope so.

Like I posted in the official 1/4 mile thread...

"For reference that track is physically 1121 feet above sealevel and your DA for that run was between 2490 and 2380 feet above sealevel. "

You can get the DA for your exact track and rough time you ran by selecting the track and date here:

I can't imagine any Cali track having DA values of 5000+ like us here in Denver, shoot the hottest point of your day that day was at ~3:00pm and DA was ~3700 feet.

A few other toronto S4 memebers will be making the trip back to TMP the end of September and/or the beginning of October. If your interested to join us you are more then welcome just PM me your info.

OP - based on your DA that time is very respectable. It does suck that based on where you live your DA's will always be pretty high but all that means is you need to plan a road trip! ;)

That makes a lot more sense. I was positive I was doing that wrong.
