1st time track First time at the track tonight (houston raceway park), first run i had a passenger in my car and I didnt realize how sticky the track was so with a pretty weak launch i ran a 13.710 at 102.68 mph. Second run, I did by myself with a slightly higher power-brake launch (17-1800 rpm's or so) but the improvement was minimal, I ran a 13.541 at 103.17 mph. The only mods on my car is the SLP cold air intake, SLP lid, K&N filter, smooth bellows, and a 3" cutout. Is this time normal for an A4 car or is it just too damn slow like I think it is? I just bought this car a little over a year ago, and as far as I could tell the engine has never been tuned up, and i've never done a full car service/maintainance.

Perfectly normal trap speed for an A4 that is close to stock from what i've seen. A few eek into 105mph at my track, but i've seen some duds trap as low as 101mph. Feel for those guys, cause they barely break into the 13's. Besides you are running mid 13's. Don't look at the mph, look at the E.T.

Also when I was burning out in the burnout box to clean my tires, the first time with my friend in the passenger seat, instead of squealing the tires the whole car was like vibrating and making really quick thumping noises from the rear while the car kinda slipped towards the left. The second time, I was able to spin up the tires but the car was rocking back and forth like the front brakes were loosening up and then tightening up again and again. What's causing this? I let the wheels stop before moving to the staging area instead of letting it launch, is that hard on the brakes?

Times are not too shabby IMHO. One thing, if you are running a stock stall converter, I'd not launch it at 1700-1800 rpm. The converter has minimal, if any room to flash there, and you'll just push from the staging beams. I launch mine about 900-1000 rpm, and this allows the suspension to work a little more and get 2.0 60 foots in the summertime.
If the car hasn't been attended too in a while, I'd change fuel filter and plugs at least (I'm assuming engine oil, trans fluid and rear end oil are in good shape).
Good luck getting faster!

Otherwise it might be a motor mount. Those are just guesses though.

The car wasnt vibrating when the wheels were spinning the second time, so I doubt it's the motor mount. I'm not sure about the wheel hop though. I have had several incidences where I would hit the gas pretty hard and the wheels, instead of burning out, does a series of thumps like the wheel's suddenly catching traction in pulses. I still couldn't figure out why the car was rocking back and forth in the second burnout, my foot was pretty hard on the brakes so I wasnt letting loose and pushing down.

That's an average time i'd say. About the same as me, but I trapped only 103, and that was after the longtubes and exhaust (but untuned).

BTW, I was looking at my RPMs in the 2nd to 3rd shift and it seemed to shift at 6500 rpm's. I've never banged the rev limiter on my car and I dunno if the previous owner ever tuned it so I dont know where it's set at, but is a 6500 rpm shift right for a stock 4L60E?

I must say my auto was soooo much easier to launch.

If you're running street tires, you want to roll into the gas as quickly as the tires stay hooked up. I've gone 2.00 on stock 16" goodyears on a cold night with good track prep, but it takes time to learn. You can always snag some drag radials and then launch WOT without fear of spinning, but that's up to you.
Good luck!
