'88 911 targa redline in 5th which is around 150-152 somewhere on I10 in LA with an S2000 behind me but easily keeping up. When I hit redline, I pulled over and let off. It had a front spoiler, but no rear spoiler. It probably also had 90k miles on the struts, although they seemed OK. I definitely noticed the rear end feeling light, but the front felt OK.

'08 Boxster S, indicated 152. (obviously not air-cooled) The GPS in my phone usually puts the speedo 1-2mph optimistic at regular speeds, so maybe 2-3mph at that speed.

Grady was a heck of a guy. RIP.

160 and change in a modified 930.

275 Km/h in our 930 on german highway. Stopwatch verified.

115 mph on both the front and back straights at VIR in my SC. Car would start to get "light" and I would lift.

South Eastern Freeway just near Callington. 1.00am. A few hi-po cars ahead to check for police.

My SC never had the front spoiler. I went 114 into a head wind once. Super sketchy. The airflow felt wrong.

Funny? I was on a fishing trip to Montana with my son in my 100 series Land Cruiser. I looked down at the speedo and saw 95!

I'm guessing a little north of 140, traveling northbound on 580, next to Washoe Lake...between Carson City and Reno.

I've also seen 110 in my Cooper S, on 285, outside of Atlanta.

try 160 with the sunroof open . LOUD.

i wanted to do the road course at charlotte in my late model race car.

Hum...

rather not say Audi R8 Plus

^^^ Heck, in the interest in keeping my car insurance, I'd rather not say.

In my 88' it hit 149 a few times.

19.8 seconds for a measured mile. Middle on nowhere FM north Texas. Roads there are like the ET highway,

I hit ~140-145 with the targa top off once. It was scary loud. I was half expecting the rear window to blow out.

That's pretty impressive. I'd have thought 1 they didn't have the power to go that fast and 2 they weren't geared to get to that speed.

with the stock 3 liter it would not go beyond 140. I have a slightly massaged 3.2 on it!

That speed reading was courtesy of a friendly patrolman

Ah, yes, that would do it. And independently verified! Congrats!

he he he. He was very friendly.

Weren't you driving the white GT3R at Sebring earlier today? Ahem, yes?????

I guess this one is not as fast.... I'll give you a ticket for seatbelt since I would have to throw you in jail overnight otherwise......

He was cool. Even said be careful, lots of patrols on 27 including a plane

Very nice!

Oddly, I felt the exact opposite. I took several trips in my M5 while living in Germany. One, sans family, down towards Swiss border on the A7 near Ulm (down where Abt is headquartered). I recall around 125 mph or a bit north of that. Felt totally comfortable since it was very light traffic and that section of Autobahn was unrestricted.

On the flip side, when driving on the 'Ring I was wetting myself. It is scary as all get out and the motorcycles close you down pretty fast. I also didn't want to crack up my car.

In my 911E I don't think I ever made it over 80 or 85. Just not as comfortable in that as in other cars.
