Default 13.15@102.6

That's what I hit tonight. I was hoping for 13.1@103, but I got the important part.

Temps were in the mid 60 range so DA was probably in the 1700' range.

My previous best was a 13.46@100 but I added some LPPs and their Y pipe with no catback at all.

Full mods:

3.42s
MadZ tune
3200 performabuilt stall
LPP LT/ORY
OEM ram air intake


Is this average?

I'm hoping for 12s with some rockers and the free mods I never did. I might need some skinnies to actually do it, but who knows. Racing season is almost over here.

Oh yeah, finally got a 60' time: 1.82 stock suspension, just a set of MT ET streets.

i feel you are right on with your mods,toss some 1.6s on there you will definately hit 12s.


i have the same mods as you(close) and i run 13.30s bogged out 60' (2.0) at 105 so i would say you are in the ball park.....
how many passes did you get?

sounds about right to me, i'd do a search on the RR's though, i have rear quite a few threads on them and seems to be some mixed reviews on just doing the RR's definatly a great mod with a cam but just doing the RR's not as much of a gain as some would expect it seems

Congrats, 13.1 isnt bad at all for your mods listed.

Were do you live? I could see that car biting a bit harder and 60' 1.7ish and a 12.9 pass in your lap. Were do you leave on the converter?

I agree with MonmouthCtyLS7. The trap speed seems to be off just a little, but otherwise it seems right on track.

I was getting the exact same 60' times with a stock suspension and MT 255/50/16 DR's on the stock wheels with 3.42 gears. Changing to Weld Drag Lites with skinnies on the front, 3.73 gears, and a little weight reduction got me some low 1.7 60' foot times. I changed to 4.10 gears and it dropped to a 1.65 60'.

Seems to be pretty on but I think you could go a little faster. I was doing 13.40's at 103.5mph with only mods being LT's, ORY, Catback in my Auto with street tires cutting 2.0-2.05 60's.

i wouldnt worry about your trap speed as long as you are happy with the e.t. Mine traps low also, probably due to the stall. Do you also have a performabuilt trans also or just the stall? what was your 60ft.?

Couple things, I had a misfire right before i left with a burnt wire. I fixed it, but I still have a random misfire that I haven't been able to fix yet. I also threw a bad o2 code.
My car only dyno'd 231/270 stock, so I started off slower than most other A4s

I've gained almost 8mph from my mods (95ish-102.6) which to me is pretty decent.

Also, I'm in Arizona so getting better times probably won't happen unless the daytime temps drop below 80. (not this year!)

It was in the 80s all day and it started to cool off a bit before the runs. It was still mid 60s when I got the 13.1

I did 3 runs, the first one I was at operating temp and ran 13.22@102.09 with a 1.85 60'
Run 2 was 8 minutes later 13.28@101.5 1.86 60'
Third run I let it cool for an hour and a half, pushed it through the staging lanes and did my best time with a 1.82 60'

If I get another chance to run this year at the other track on a cold day I will, but it's unlikely.

AZ is NOT a good place to get good times and the DA wasn't great. I'm only guessing at the 1700' but it was probably worse.

I'm not too far off from what I wanted with traps... I just wanted to outtrap my old GTP that did 103mph with a 13.4 on street tires... sad that my TA can't beat it with longtubes.

The transmission is a stage 2 performa

Oh and stealth your car also has 7x less miles than mine. I could only dream of having that few miles on my motor!!

You guys saying my traps are low, what would you expect from a stalled auto with the few bolt ons I have??

I also want to make sure that you all know I am not getting defensive/angry at all, I'm just wondering.

That wasn't from my WS6 it was my old '95 Formula that had 79,000 miles at the time, unfortunately I never got any bolton times with the WS6. I think your mph makes sense because the stall eats away at that so I think your right on there. ET wise I think your a pretty damn on but I think you could cut another .10th or a tad more but where I race is different from where you race so its hard to compare. I don't know anything about AZ except its hot but I race in NJ where its sea level so its probaly a little better situation.

EDIT: I see your adjusted time above, now thats right on!

How have you liked that trans? I'm stuck between a few companies and Performabuilt is actually close by to me. I think its getting about time I need to put a new one in sadly enough with my mileage.

I thoroughly enjoy my transmission. It hits hard when I gas it and it's lighter when I don't. No problems yet. I would not hesitate to get another if needed. It still chirps the tires in shifts with the stall, which is very cool.

I don't think it's possible in this state... maybe I'll take a trip out somewhere at sea level... the other track on the opposite side of town is a little bit faster though...

Considering the temps and altitude you ran in, I revise my opinon. If you could run in some near zero DA like some of us do, I could see it picking up a couple of mph. You're on the right track!

Yeah, there's some lucky bastards out there that get to run in negative DA.
