Atco today with my C7
Today I took the car to a rental put on by MustangJunkies.com. It's a bone stock C7, Z51, A6 with MSRC and NPP.
I was hoping for a bit better weather today, and it started off cool, but by late-morning was into the 60's. Not great weather, but certainly not bad. This was from around 1 pm and I made a few passes around then...
Based on applying the NHRA correction factors to the passes that Al/Z06 made last weekend in Illinois in his A6 car, I was hoping to see some 11.5's at ~120 mph today. Unfortunately, I was wrong.
It only went 11.67 at 119.7 mph.
And if I'm not mistaken, every single pass there is quicker than the #1 car on the C6 LS3 "Fast List". The third pass I listed is against my buddy's '13 GT500 on DR's. He was a little quicker, but I got him at the tree. The RT (and I don't typically worry about that during T&T and rentals) on the fourth pass shown is off because I was re-setting the 0-60 accelerometer to compare it to Vbox data. Incidentally, it went a 3.60 0-60 on that pass, compared to a 3.8 on the DIC display.
I made 7 passes. Note that the car ran 11.6x both at around 10:30 am and again at 1:39 pm. It had a pretty decent (~45 minute) cooldown both times. The hot-lapped passes were 11.70's.
Slowest pass of the day was when I tried launching with some rpm (~2000) off the footbrake, it didn't seem to like it and only ran an 11.807 at 118.15 on a 1.758 60'. The car simply likes the convertor to be flashed on the 2nd yellow and that's it. It ran consistently from lane to lane and I had it in "Tr" and let it shift automatically. Next time out I'll play with manual shifting, which may result in even quicker times as I think the car could stretch out the 1-2 and 2-3 shift points a bit. I ran it once in "S" mode, and it went 11.780 at 118.92 on a 1.771 60'. I'm not sure if that was an anomaly but that will be some more experimenting during future track days.
It'll go faster. I had one-notch below a 1/2 tank of fuel and I weigh ~230. Put a 160# driver in, run it around 1/8 tank, wait for some better temps and an A6 car is going to go 11.3-.4. Mark my words.
There were a few guys videoing, and my buddy with the GT500 caught some passes on his camera that he emailed to me. I'm sure the links will be out there in the next few days.

It will be interesting to see if any of the manual tranny hot shoe drivers can equal these mid 1.7s 60' times. It will be hard to do with a manual tranny but possible. Looking over at the Z06 fast list, your time would put you 23 on the stock list but your 60' time would be 3rd best, but that is the beauty of the auto at the drag strip.

The Z06 has a 325 which helps some, but when you are talking about a street tire the track prep dictates your launch more than anything with an auto. I am sure the extra low end torque over the LS3 is helping the 60'times too.

That is 60 foot time not 60 mph time, so the fact the Z06 shifts after 60 mph has no bearing on the 60 foot time. 60' time is all about the launch which is where the money is made at the drag strip.
