My car is a 99 Z28 M6 set up for SCCA ESP autocross (Watts link, heavy sway bars, stiff springs, etc). My street tires are uninspiring 315 Sumitomos. I've not been able to hit a drag strip yet, but I'm curious about what the car is capable of. A recent trip to a (pretty friendly) Dynojet said I have 343 rwhp and 354 rwlb-ft. Engine mods are basic: longtubes, LS6 intake, ported TB, UD pulley, and a tune. The car's weight is 3365.
For reference, I have run my 05 CTS-V and it went 13.63@108.5, but those cars can't launch to save their lives (2.2-sec 60 foot time). I had that car on the same dyno and from 2500-5000 the Camaro makes a steady 10-15 hp more than the Caddy. From 5200-6500 the V has more power, though. See the attached graph: blue is the Camaro, green is the Caddy. Ignore the red lines (my Thunderbird SC).
I realize the only way to check for sure is to hit the strip, but until I can do that, is anyone willing to wager a guessas to my potential times? When I run it will be on street tires, I don't drag race enough to justify special tires.
