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.

My guess is about 12.6-12.9 depending on your elevation and 60ft times. If you in the 2.0-2.1 60 ft range my guess is a 12.8 or so and if its any less than I bet you could get 12.6ish

343rwhp and 354 rwtq you should be in the 12s if you hook..

-big front bar
-stiff rear springs
-probably lowered with no relocation brackets (not ESP legal)
-sumitomos

good luck hooking my friend hahah. you'll probably hit 12's but that launch will be tricky.
