    my car has been to 136 in fourth gear on the front stretch of pacific raceways, and that's putting the pedal in the carpet and pulling on the steering wheel for extra leg/foot leverage, it might go faster in fourth but I haven't tried a longer pull than that stretch.

    Want to know what's more interesting is if you swap out the stock 3.70 diff for the A8's 2.62 then 6th gear tops out over 300MPH at 309.11!!!!!

    I did a top speed run on my stock M6 on the dyno and I could only get to 180 mph because it was overheating. I found a stretch of road and did a top speed run and could only get to 176. The temps were normal but the needle wasn't moving up much more and I let out for fear of getting caught at those speeds. From the reading I have done it takes a mile to get up to the 170s and several more miles to get anymore than that.

    Bad Kitty did 193.2 at the Arkansas Mile in 5th gear, with redline at 6500. Not stock, of course.
