Off the line, was at a light with a yellow M3, I was feelin a bit grumpy, so revved a bit. Had my windows down because it was nice and cool out (50's). So I heard his I6 wind up in response. I gave the full on V8 rev, and he perked up and revved his motor full out. (My raspy angry V8 sounded cooler to me.) I alread had traction control off, no ac on, etc, so all I did was put it back in D, hold the brake and feather the gas to load my torque coverter. Light turned green and I launched the fleetwood for everything she had, tires were scrabbling a bit, but with a pair of 255's being held in place by a big butt and posi, she dug in well. He chirped his tires, but there wasnt much power there, so I beat him off the line. Bigtime... I was across the intersection, and he had fallen back to leel with my trunk. I still had my lead at the barked 1-2 shift around 40. (Remember, I have 3.42 gear set and posi on a computer tweaked LT1.) He was still only in my back door. He also chirped his 1-2 I think, but I don't recall where it was... By 70 he had climbed back up to my front door, and by 80 he was level bumper to bumper. We both shut it down there because we were approaching a curve, not sharp, but not an 80 mph curve either. Needless to say, I was much happier about my day then.
