New times with new stall. Hey guys, I posted a few weeks ago about purchasing a 3600 vig stall, now it's in.
Car: 99 A4, lid, ls6 intake, tune, knock-off muffler, and now a 3600 vig with a trans cooler and shift kit to compliment it. I also picked up a set of m/t et streets for tires since I knew I'd be blowing them off.
I use this car as a daily driver, so I didn't want it to be a pain to drive. I think I made the right choice with the 3600 though, it seems perfect. It slips a little bit but once it goes into lockup it's like it's not even there. Plus, nailing the throttle makes me happy so it's worth it. I'm glad that I didn't go any smaller than a 3600, even though others told me to.
My best time before the stall (just 1/8th around here, sorry) was a 8.23 @ 87.5 mph. It was a pretty cool day. Sorry I don't have the d/a for you but it was about 55 degrees or so.
I ran it today and it was unseasonably warm for February. It was about 65 degrees and I knew it was somewhat humid because my hair was frizzy
With the drag radials it is consistent as hell. I had about four or five 8.05 @ 85mph runs with 1.70 60's. Within hundredths of each other - very impressive. It cooled down a touch later in the day and I did two better passes, 7.97 and 7.99 @ 85.5mph with 1.63 60's. I think it could go a little faster if the weather was more accomodating. I thought/hoped it would be in the 7.80's, but I guess I expected a little too much. I was told it takes about .5 off of a quarter mile, so losing 2.5 tenths in the 1/8th is about right I surmise...
I do have a question though. When I had these tires before I remembered having to do a pretty significant burnout with them, so that's what I did today. With a burnout like that it 60'd 1.7X every time. When I cut burnout time in half, it dropped a tenth to the 1.6X's. Is it just putting too much heat through the trans when you do long burnouts? From now on I'll continue with the shorter ones. I basically wet the tires, and burn out until I see them start to smoke, and then pull up to the line.
Launching is a piece of cake as is. With a good burnout, it doesn't make enough power to spin at the launch - so I floor it and bam, it hooks and goes.
I am definitely very pleased with this modification!!

nice times, that appears to be a strong car sans headers.
my fuddle 4k stall dropped .55 off of my 1/8 mile ET (with a 1.70 60') when the car was stock except for a lid, 373s, and shiftkit. on the stock tune it banged the limiter like 8 times on 2-3 and layed down HARD on the shifts (i went with the transgo "full-race/high stall" shift kit, it hit too hard for tqm to cooperate..
went from 8.73 @ 83 to 8.18 @ 80. after tuning and more parts, the car went high 7.6x with bolt-ons.

true duals
ls6 intake

no "free mods"..
stock (untouched) tb + maf, etc
i honestly wouldn't invest any money in a set of 373s - i did because i had a factory 273 car. get a girdle and call the rear done. there's no reason you shouldn't go 7.50s with that car after some parts. i sold mine at the end of summer and never got a chance to race in sub 85* weather (da ~2,500')...i'm convinced the car would've gone 7.50s with good weather and an on-time 2-3 shift.
you know adding headers to these engines is like spraying a 50 shot on most anything else.
