I did 160+ mph in a 991 C4S cabriolet on the Autobahn with the top down earlier this year. In retrospect, I should have left the top up.

Highway 50!! Been there done that when I drove a X5 4.6is I had just purchased from CO to CA. I had some nice 120-125 stretches in there!

Fastest I have been is 165 but that was in a closed highway open road race event in a 1991 corvette with a few aero mods. It was completely stable at those speeds. Still quite a rush even tho we had full safety gear on and a roll bar with harnesses.

I did 156 in my old E60 M5. It had more to give, but I got scared. Death and/or jail.

There was an article published -- it has been years now -- in one of the major USA mags about where its reviewers/testers can top speed test cars without having to rent a track. A number of locations -- private roads in some cases -- were divulged.

That's all I'm saying.

On a road trip east I entered NV on 50 and drove on east. A little ways further into the state away from any real population to where the land ahead looked to be just nothing but basin and range I came upon a road side sobriety check point manned by a large number of LEO's. I pulled up and stopped and rolled down the Turbo driver's window. The deputy leaned into the open window a ways and said something like "I hope you aren't driving this fine automobile drunk". I replied no. I had the idea of asking him if all the LEO's manning this check point meant the road ahead was uum, clear? But I thought better of it.

But as it turned out, the road ahead was, uum, clear.

I did the same with the top down, not on the Autobahn though. I've maxed out with the top closed years later.

I rode the chopper in the picture at 152mph on a road right outside Las Vegas. The chopper has a 400hp CHEVY ZZ4 in it.

The exact reason I wont/wouldn't purchase a bike, I would have done the same plus!

Wouldn't you burn your legs so close to the exhaust headers? It's amazing they crammed and auto motor on that bike.

Actually the engine puts out less heat than a full dress Harley. It runs at about 170 degrees because it thinks its on an engine stand. Its never working hard at all. Its a 10 second bike even with the street tire if you manage the throttle properly. I been riding it for 6 years and it never breaks or leaks. Its an automatic. It makes a nice companion for my Porsche when its in the garage.
