I made it back to Atco for a track rental put on by the NJFBOA guys. Brian was kind enough to make a slot for me.
Car is a bone stock '14 Corvette Z51, A6 with MSRC and NPP on stock Michelins.
I only made 6 passes today. I spent the weekend hauling @ss around Sebring International Raceway and flew back up to NJ late last night, so I wanted to get in and back out of Atco quickly. The car didn't really get extended cool down times, and I was looking at coolant/engine temps on the DIC and they were in the ~130-140* range ("S" mode DIC display) before I pulled out of the pit to make any passes. I ran doubles, so three passes were fresh and three were hotlapped (the 11.51 was hotlapped). The LT1 doesn't seem to fall down very much on back to back passes.
Air was, predictably, very good. It's unseasonably cold and the DA was very nice. This was from 12:54 (close to when I ran one of passes shown on slips):
Because the air was so good, I was hoping to improve on the 11.67 from a few weeks ago, I was not disappointed (but would have like to have seen an 11.3):
(Note that Atco's dates are still wrong, just as they were a few weeks ago. They also did not adjust their clock for Daylight Savings Time.)
Interestingly, on the 11.49 pass, the car 'hiccupped' on the 3-4 shift. Basically, it touched the limiter for a split second before shifting, was very strange and I would guess that trap speed would have been over 120 mph based on the 1/8 speed. Interestingly (or not), my '12 GT-R did this a few times when it was stock.
I ran the car in automatic mode in "Tr" all day with the exception of the last pass. I decided to manually shift and bumped the limiter on the 1-2. Since the track was sort of going away (cut a 1.76 and spun slightly on that pass), I decided to call it a day. That was the slowest pass of the day at 11.754 at 119.58 mph. It also went an 11.54 and an 11.58. The car had ~1/4 of a tank of fuel when I got to the track and just over 1/8th when I left. Once again, I didn't touch the tire pressure or pull any tricks. It was parked in the pits all day with the hood open, plenty of people taking pictures. I know there were some people taking video, but not sure what passes they got. A friend of mine was going to go, but decided to just take the day off work instead.
Think this is a pretty good pic taken by a guy shooting pics at the track. He gave me a hardcopy for $20 and I scanned it:
