Thanks for the info! Interesting reading. Only, how do I do it on street tires?
A sticky set of 15" drag radials (BFG, M/T, or Nitto) might get you there also the way that Bill Putnam describes it in his post that I linked.
There are other ways to do it also. The only weight reduction I have is from removing my spare and jack. My suspension also leaves much to be desired for drag racing compared to what Bill describes. I have run 12.90 and 12.97 in my car just recently with the following mods:
Comp Cams XE270AHs
Mac Long Tubes
Trubendz X-pipe
Magnaflow catback piping with Spintech mufflers
C&L Upper Plenum
Accufab Throttle body
Steeda CAI
Steeda U/D pullies
Dynotune/chip
FRPP 3.73s
BFG 275/50R15 Drag Radials
Here's my 12.97 pass:

My car still has more in it, but I need to keep working on my driving and it really needs a set of 4.10s or 4.30s to go with the powerband of the cams I have. And my rev-limiter needs to be raised so I'm not cutting the power off at 6250RPM.
Of course, you could also just get a good set of 4.10s, sticky tires, and a good nitrous setup and get twelves, but its not always at your disposal. I'd rather have the power on tap at all times. Yet another way you could do it is to go with one of T&Js Mongoose kits with either a Vortech or Paxton supercharger. There are many other kits, but theirs is complete and proven.
Good luck with whatever you go with. I've had a couple LS1s (Formula M^s) in the past and they were a blast too, but feel like you're driving a tank.
