I normally run at Maryland International Raceway, the only IHRA track in my area. As you may know the NHRA limit is 12.000. Under that and you get the boot. MIR is annual host of the IHRA nationals for this region. So their timing equipment is certified.
My 02 Z06 has a best pass bone stock(zero mod; and stock original tires) of 11.81.
Slip It has a bunch of passes in the 11.8s and 11.9s.
I had the opportunity to run my my car (bone stock EXCEPT drag radials and a cold air intake; 363 rwhp and 350 rwtq) at one of Jason Heffner's private track rentals (Maryland International Raceway; November 15, 2002) for some of his Viper customers and others.
So we had a bunch of Gen 1 and 2 Vipers at the same track, same day, plus my Z06. Great time. Great bunch of car enthusiasts.
Density Altitude throughout the day was 400 to 500'. Air temp was high 50s-low 60s. Humidity was 50-60%.
So what did my Z06 run that day? Here are 15 runs in sequence with the 60' times included:
11.568 @ 117.94 on a 1.684 60'
11.651 @ 118.44 on a 1.728 60'
11.755 @ 117.80 on a 1.805 60'
11.707 @ 119.46 on a 1.704 60'
11.640 @ 118.16 on a 1.693 60'
11.715 @ 117.73 on a 1.752 60'
11.700 @ 118.04 on a 1.743 60'
11.778 @ 119.46 on a 1.797 60'
11.748 @ 119.38 on a 1.777 60'
11.726 @ 117.53 on a 1.774 60'
11.719 @ 117.49 on a 1.722 60'
11.742 @ 116.97 on a 1.756 60'
11.763 @ 116.87 on a 1.735 60'
11.766 @ 117.05 on a 1.776 60'
11.786 @ 116.99 on a 1.756 60'
My car was getting pretty heat-soaked as the day wore on and the launch surface got progressively "run-off." Jason can vouch this. Also Jamie Furman, who owns a blue GTS.
BTW, with the DRs and CAI the car has 75 passes in the 11.7s or better with a best of 11.55
Slip. (Jamie Furman witnessed this pass). My best trap is 120.54...at DA of 62 feet.

I admire your Vipers very much, and they are very fast, especially in the hands of the right driver. Conversely, a Z06 can be very fast too with the right driver doing the launch and shifts.
Safe racing to all of you.
