First trip to the track...kinda frustrated

Went to the local track Saturday night to see where the car is sitting. Weather was ok for July, 80 Degrees with 48% humidity. DA was around 3060 that night.

I was able to get three passes in before a bad wreck at the top end of the track and all were right at 12.60 @ 110. What is driving me nuts is I couldn't 60' better than a 1.9x.

Car is fairly stock A6 with 3:15 gears with an airraid CAI, muffler deletes, BMR SP009 springs, LCA's and relocation brackets and a weak 91 BAMA tune. I was on 275/50 Mickey Thompson ET S/S @ 16 psi and was still spinning through first. Tried stalling up to about 1500 and leaving off idle, no difference really. Something was keeping the car from doing a full burnout, so I wasn't able to heat up the tires very well. Traction control and advanced trac was turned off by holding down the button for 5 seconds. Maybe I'm worked up over nothing but I expected more....

The near future I'm going to get a new tune but the stall and other items will have to wait as the wife and I just bought a house.

Not sure if it helps but the best run of the night. 12.60 @110.7

It's not a terrible slip by any means. Get a better tune and try again, I bet your times improve. Or stall it, tune it, and run 11s lol.

60' should be better than that bone stock with drag radials, let alone with your mods. I went 1.92 60' 100% stock down to the awful factory Pirellis (12.76@114) in my '14 GT Track Pack. Only other thing I can think of besides your burnout issue is the track prep might have been subpar.

Et isn't much off what a street tire Mustang GT auto is gonna do but, the mph is a little low. However, the high DA and hot air with relatively high humidity could be sapping some performance.

I didn't Et much better than that Na, even with a sticky, non dot tire, because the car would not 60' with the stock converter on a prepared surface. It would bust 112 mph easily out the back door, though. So, not wanting to open it up, I threw a 100 shot of spray at it and it went 11.4 at over 120 mph, first pass.

Track prep wasn't great, it was a grudge match night and prep is not great. The one time I stalled to about 1500 RPM I spun badly through first. It was a 2.1 60'.

I kept telling myself the DA was crap to try to alleviate how irritated I was but it didn't help much. I never went to the track on my street tires, when I bought the car it came with Michelin Pilot sport all seasons and those will spin for days on the street. I was expecting at least 1.7x 60' on the drag radials.

I guess I'll get that better tune and try again. I'd like to see some lower 12's before getting deeper with performance mods and maybe a little spray.

1.6 sixtys are easy on a slick, even with an unmodified rear suspension. I did that with just poly arms, stock springs, shocks and bars on both my s197s. The suspension ain't too bad on this car, once it gets some rubber under it that'll hold up. One thing I've found with all DRs I've tried is you need to heat the living shit out of them for them to work. 10 seconds of smoke at least. On a slick I can basically get 2-3 seconds and it's good to go.

Track prep is serious. I run in Outlaw at my street legal drags because they prep the track for those guys. I get my ass handed to me regularly on my stock Mustang plus spray but, it's less frustrating.

your 60 foot is fine- it is the converter holding you back- I use to run 1.92 on the p zeros and was deeply depressed when my 60 foot went from 1.92- 1.88 on a mt 18" dr- 650$ for 4 /100ths, 3.15 gear a6 wont 60 foot better than a low 1.8 on the stock converter period unless it has excessive weight removal.

Like mentioned, the DA was hurting you a little on your runs. But with a lower DA, I bet your 60' wouldn't change, but you might have seen a lower 12 run. I ran a 2.0 60', 12.4 @ 113.8 on stock tires and suspension, had a Lund tune, jlt cai and borla ATAK axle backs. DA was around 900 and temps in the mid 80's.
Stall will help a lot. It dropped my 2.0 to a 1.7 off the bat.
Try to go back when the temps are cooler too see an improved ET and mph. And it's true that DR's need to be heated up pretty good.
Once you can get a stall...night and day difference.

As for you not being able to burnout well, I experienced the same thing last Saturday. I had to drop the clutch at 6500-7000 RPM's at 15psi in the tires to turn them over. I have 275/60/15's.

I'm going to try to make it back in the next couple weeks at one of the test & tunes. Hopefully by then I'll have a new tune. Also need to start stashing money away for a stall.

Hey man don't sweat it. You still have cats, a lot of the people you are comparing your slips with have cat deletes or a lot of weight reduction, which makes a big difference on these cars. Also, you need to take into account you are racing at 3600' DA, and a lot of people with amazing slips are at tracks that see negative DA days in the spring and fall.

Your ET is actually pretty decent for your MPH. I had the same issue with burnouts in my 2013 until I switched to an AED tune. I found that starting the burnout with barely any brake pedal, and then hitting the brakes helped. It is a computer thing seeing no movement and too much RPM.

I can flat foot my car and get 1.95-2.0 60's NA with the stock converter even with a centrifugal blower. If you are spinning now, a converter will make it spin worse. I found doing a burnout through 1st and into 2nd with select shift cured my traction issues, but don't expect to 60' much better it will just bog.

My car with similar mods and same DA did 12.8's at 109-110 mph.

Save up and get a converter, until you get your 60' down all other mods don't really matter. Also, an AED tune will probably cure the burnout issue for you and will work well with a Circle D 4c.
