I am a C5. With stock internals on runflat street tires I went 12.72 (2.1 sixty) and a best mph of 111.03mph into a 14mph headwind.

With DR's shooting for 12.20-12.30@112-113mph and a 1.7X sixty on a perfect day

Halltech stinger, TPIS headers, 160 stat and Z06 catback are only mods.

OctaneZ28 was running 12.1s last year prior to his headers. He should probably be in the 11s in a couple weekends.

Good luck .The problem I had when boltons w/2.73s was the car would bog real bad off the line, its better now with more power off the line. The good thing is the car rarely spins out of the hole w/2.73s.

When I break the 3.42 rear and I have to swap back to my spare maybe I'll give it another go. Good luck.
