July 3rd was track day. I came up to Pa to see Family and my brother and I went to the track yesterday. He took his 2009 Impala SS and I took the Z06.
His Impala runs real consistant 14.4-14.5. It's bone stock and that suprised the heck out of me. I was expecting him to run a high 14 with it. He ran with a couple Mustang GT's and his car is quicker than a 99-04 GT auto and runs with the sticks he encountered. He ran a LT1 Camaro and beat it at the light. The LT1 ran 14.37 to my brothers 14.45, but my brother cut a .007 light and the Camaro cut a .35x light.
The Z06 really likes the cool dry air up here. Cool being relative. It was mid to upper 80's with low humidity. I pretty consistantly ran 11.9 to 12.1 on the street tires.
I ran a guy with an 03 Cobra 3 times. He had a pulley, an intake and a tune and we were so close it wasn't funny. I won the last race for a best of the 3 races, but the times were 12.060 for me and 12.093 for him with me cutting a .055 light and him cutting a .067 light. He was just slightly faster through the 1/8 every time.
I also saw a 2011 5.0 Mustang running high 12's. I think he had an intake and that was it. From what the guy with the Cobra said the new 5.0 doesn't have many cheap mods that can be done to it. They have headers and a CAI from the factory and they are pretty efficient.
I also ran an V-10 M5. The guy had a bit of work done to it and it was a good run. The Z06 got the win by almost 2 tenths.
Then we went to Orrville Ohio and watched a friend of his race his sprint car.
