What's The Fastest You've Ever Travelled Not In An Aircraft?

Back around 97 my girlfriend was in the high school homecoming parade and the local Pontiac dealership let us (her Mom actually, we were both too young to sign off on the paperwork) borrow a '97 Trans Am convertible. They let us keep it for the weekend so she and I dropped the top that night and pushed it as far as it would go on the freeway. I believe it was governed at 158 mph and we either hit that or were really close. The cool thing was there was a lot of wind buffeting from about 70 to 120ish until we hit about 130 mph and the wind was just blowing over and beside us, it was real smooth. I finally backed off, it was a little scary, especially since it wasn't our car.

I have a Dodge Challenger now with the V8 but I've only pushed it to about 100mph. My driving way fast days are way behind me.
