Back at Atco today with my C7.
 
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. :thumbs:
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:

Awesome! Super nice runs! :thumbs:

Very consistent performance. Well laid. Did you change your wheels?

Huh?
The car is bone stock on black Z51's with the factory Michelins it had on it when I bought it from Criswell.

Good job Snorman :thumbs:

Very nice times!
Looks like picking up 6 hundreds in your 60' time got you .18 in the 1/4 with the gains from the better air. Though your trap only picked up by a half mph our so, which is kind of surprising since the DA was 1100ft better.

I think that whatever happened on that first pass prevented it from pretty much running 120+ on that pass. I need to look at and compare the 1/8 data too.
I too am somewhat surprised it didn't run ~121, which was what I was expecting.

This car feels like it will hook on wet grass.

Wow! You got a fast one there! Hope mine is anywhere near as fast as that. Awesome job.

Awesome runs and you really know how to run the 1/4:rock:

racerns 11-04-2013 06:23 PM

How do these 60'ft and 1/4 times compare to what you have run in your GT-R. I have too think the 60' time has got to be close.

The '13 (run at Atco and Etown) is .4-.5 quicker and 4-5 mph faster and cuts mid-1.6 to low-1.7 60's.
I haven't run the '13 much, but comparing the C7 to my '12, which was raced LOTS at Orlando Speedworld and PBIR isn't really fair (and the '12 is no longer stock).

About what's thought, but it is pretty amazing that the c7 will launch close to what the GT-R will.

Thought I had seen silver wheels on it before. Must have been someone else's.

Very impressive runs Snorman.:thumbs: You could easily run the CC's 11.5 index right out of the box! By the way did you flash the trans again at the tree like last week or do anything different? Also, just one of my own observations....my C6 occasionally on a track day would give me a burp the same way. Could be the 1st run, the 3rd or whatever. No rhyme or reason. Even after a few thousand miles and I still wonder if it's a anomally in the A6's software or torque management.:rofl: Had other buddies with A6's that did the same thing.
Even so I'm really impressed with how your car runs. Since I've moved down here and can't go to Atco or E Town I'm wondering have you ever run Bradenton? A couple of guys from the CC ran there & said they prepped it well.

You and that car are really consistent. Well done. :cheers:

That's amazing, I was at the track on Sunday with similar conditions and there was a C7 M7 running low 13's with 109 mph which was the most disappointing part. I totally understand the differences between an auto and manual but the low mph was the most disappointing part.

DallasC7 11-04-2013 07:21 PM

Sweet runs!
