307kph GPS confirmed in my modified Lotus in the Outback.

140-150 in the LP-560, I've hit 170+ 2 dozen times in a Z06, at least 5 times I set my mind on going for 200mph in that car, but always chickened out around 175.

My thrills are acceleration, corners, brakes, and sound, not really high speeds. Although its quite a rush hitting those mid triple digit speeds. I just start worrying about death, lol.

I was too! Anything happens...a deer jumps out, a tire blows, I'm dead!

Don't think it'll be an often thing, but doing once was amazing!

My goal was to hit >150 MPH and I did....so now I'm done with that!

There is one safe place, however I would need a spotter. The H-3 freeway has a long stretch with no entry/exits and no chance of hitting any kind of animal (almost no chance, we do have the mongoose), just need someone on a cell phone up ahead to give me the all clear. This is tempting, but for now I just have to enjoy the short bursts.

I did 165mph at Pocono - but after double checking the speedo in the G against the Z06 - it was realistically 155. The Lambo speedo reads high, and the faster you go - the higher the reading (as was stated earlier).

In either car I'm "comfortable" up to speeds of about 150 (which means 160 indicated in the Lambo) but anything faster and things happen so fast it gets scary. Like dreamcars99 said, the thrill for me is the corners and acceleration/deceleration.

I capped my speeds (in the Z06) at Road America at about 145 on the front straight. Despite being one of the longest, fastest road courses - the undulating pavement of the front straight was not confidence inspiring and tended to upset the car.

I'm not afraid to admit that my comfort zone stops around 150 mph on a race track.

Andy - I'm glad you set up a gopro to check speed. The last thing anyone should be doing is staring at their instruments. On track we only check instruments once per lap - usually on the longest straight, and it's a quick glance to be sure nothing is wrong (I focus on temps and warning lights and rarely look at tach and almost never at speedo).

Sort of a related story - here in Pittsburgh our rivers have locks - in some cases every couple of miles. A friend with a jet ski loaned it to an adult friend. The guy had never been on a jet ski but was familiar with them, and road motorcycles and was a pretty reliable/responsible guy. He set off the the jet ski, and was so intently staring at the speedo to achieve top speed - he completely missed the HUGE sign in the middle of the river warning of a dam up ahead. He ended up flying over the dam and was incredibly lucky to land (the drop was maybe 10 feet) and keep going without crashing head first into the river below. He had to go through the lock to get back up river, and got chewed out by the lock master (which was well deserved), and then had to sheepishly show back up at the dock where everyone on the boat was worried sick about the guy after seeing him disappear downriver. It could have been a disaster but he was one lucky guy. Needless to say our friend doesn't loan the jet ski to newbies anymore.

exactly, very intense indeed

I also feel quite comfortable up to about 140-150 mph, even on twistier roads and "near urban" environments where things happen around you, but faster than that it's the stopping distances that scare me.

Things are coming at you only marginally faster at 175 vs 140mph, but the difference stopping distance is HUGE, almost double I think. At 140 mph you brake with confidence, faster than that it doesn't even feel like you're slowing down for the first second and that's what's unnerving. At higher than 150mph the stopping distance is beyond what you can see or react to, so things start becoming out of your hands, and that uncertainty is what makes it scary, especially since you are still responsible even if you can't see it.

To me anyway...

Why is the speedo off in the G's? It adds more mileage to the car then actually driven. I thought my car felt like it was going slower than the speedo indicated!

That is a good point about the mileage. I wonder if speedos in kilometers are off as well?
