The weather seemed good so I went to the track last night. Went to VA Motorsports Park since Richmond Dragway still isn't finished with resurfacing. Place was packed. Lots of break downs and track clean-up. Only got 2 runs. Both were new best times for me though!
2015 Z06 A8. Still all stock on drag tires. DA was around -500
I was just on the dragtime site for DA and I noticed that the two DAs they have listed, one before you ran and one after is -575 or -677.

Very possible. We were using a fellow racers info who had a gauge at the track. Dragtimes wasn't working on any of our phones that night. It was the best air the Z has been in since last spring for sure!

Made it to Beech Bend Raceway Park yesterday Nov 7th and got to make 5 passes in my 2015 ZF1 A8 cp. All the runs were in the 11.80's with the best being 11.82... The weather was cloudy and the temp was stead at 60. I tried both power braking slightly, and mashing the gas from idle both results were pretty close with leaving from idle was the quickest. The slowest pass was 11.88. I did a pretty good burnout to heat the tires on all passes. the best 60ft time was 1.79..... At least that moves me up the list a few spots......

Awesome pass Dave01GT, pretty sure you just claimed my #3 spot on the list. Did you end up sending your stall out to Circle D? If yes how much stall increase did you see?
Congrats!!! on #3

Thanks! Yes the converter was sent to Circle D. I honestly haven't paid much attention to what it flashed to. I've found my best 60' by just launching off idle. They told me it would probably only be a few hundred rpms higher. I went from constant 1.63-1.65 with the stock converter to 1.53-1.55 after Circld D modified it. I am still on the factory shift points, so I always try to concentrate more on clicking the paddle and redline. That was my only clean pass I made. Most spun a bunch, or I wouldn't click in time and hit the limiter. I had a best of 6.42 1/8 but messed up a shift. Think it could've gotten a 9.89.

Other notes: I have a pulley that was making a hair over 10 psi on the dyno, but at the track it was slipping - the belt is a hair too long, so it was only seeing 8.5 psi before slipping and dropping down to 6.5 psi. Not sure if you want to list it at 10 psi, or 8.5 psi. Dynoed at 700 rwhp on 10 psi without the belt slipping.
Its too bad because it would have made it close to a 9 second pass with a little more mph. Next up raising the boost further and we'll see if we can power into the 9s.
There are a couple videos of the run that I'll try to link when I get them.
