well guys, my sig has a run down of what the car has. I ran it in january at San Antonio Raceway and only made two passes. it broke the rearend on the second. it went 12.0@110mph (60ft: 1.60; 1/8: 7.4X) letting off and getting back on it a couple of times as it bounced off the 2-3 rev limiter. I missplaced the timeslip though. That was with the stock 10 bolt on 3.73s. I'm currently waiting on my MWC 9" w/ 3.89s. I recently got it weighed at a local scale here and it weighed exactly 3155lbs w/o driver. I will be taking the a/c compressor, condenser, and accumulator, lightweight carpet and removing stuff like the rear speakers and amp, etc off. I want to get the car under 3300 w/ driver. I'm at 215 lbs. Any guesses on what the car will run? I'd like to run a 11.49 by doing those changes. I know its a bit difficult because of the weather down here in Texas, but it's definitely doable from what I've seen.

If it's the last one in your sig, you should be able to break into the 11's at that weight. But I don't think you'll be able to dial it in to 11.49. Most guys need at least a cam swap to get there, if not heads/cam. Average rule is usually .1s for every 100 lbs. Not sure if 3300 is going to be enough to touch 11.49.

11.7x @ 114-115 would be my guess.

It's gonna be tough in the summertime. It looks like you have a great setup, just the summer heat is gonna make for some brutal DA's. I wish I would have had the chance to take the AC and more stuff out of my car before I sold it.
Also, how tall are you? Maybe you could drop some weight off your body and make it 3250!

i appreciate the replies guys! The DA in south texas is crappy that's for sure. I know it'll be tough. I definitely need to get on a diet myself lol i'm 5'10 and am at 215, i was at 185 a couple of years ago so I need to get back into shape!

Yeah man, get in shape! I'm 5'10" and around 165-170. That's a 'free' 50 lbs off the raceweight.

I say in the hot air you run a 12.2.
