I was reading about this on here a little while ago. Cheetah ran a 10.x@118mph. I think it's because the auto goes 1:1 in 3rd gear at about 75mph, and the manual goes 1:1 in 4th gear at like 105mph. The closer gears keep the car in the power band more often and let the car run higher traps. Wish I had known this before I got an auto... But I'll be in the mid 12s soon, that'll be good enough for me. Well maybe torque converer and NA diff will come next - high 11s here I come :)

"Pulled the blower fan down from behind the glovebox and there was a mouse nest inside the cage fan - mom and 6 babies. Mom was dead and the reason for the smell - petrifying fast - but the babies were hanging on. At least until I fed them to the cats." [ZXtaZTT - June 19, 2002]
