I just ran a 12.47@114 in the 03 on the stock rubber, with only a drop in K&N filter, BBK X-pipe, and Flowmaster Cat-back.
The 89 runs 11.0's on motor (357 with iron roush 200 heads, Demon carb), and should be 9's on spray, but I ran 10.27@131 and lifted a cylinder head (had water in three cylinders on the passenger side bank).
I agree that 12's and faster is pretty damn fast. 13's are real respectable.
Thanks,
Jason
