150 I believe. But the speedometer is going to be off a little bit. Have to use GPS to get a truer speed. Mine read 150 and still had plenty of room.... on the track of course.
3.73's are going to have a little less top-end than someone with 3.15's, and it wasn't floating around. The car felt planted. A car with poor aero is going to "float" over every little bump.
I kind of doubt Ford's claims of 200mph with the GT500 though. 190's maybe, so they probably figured "close enough".
Realize a Veyron Super Sport with 1150bhp, shaped like a bullet, has a top end of 255mph, and that's with the rear wing down and it takes a good long while to hit that speed. With the wing up, it won't hit those speeds at all. The Veyron they ran on Top Gear had 1k BHP and hit 250mph over a 5? mile stretch of track.
Before Nascar enacted restrictor plates back in the late 80's or 90's, they would and could sometimes hit over 200mph, but they were having too many incidents, and those cars look like go-karts in person. On tv, they look a lot bigger than they actually are. I'm surprised Tony Stewart can even fit through the window. lol.
As others have said I would say top end for a mostly stock auto with 3.15's is 165-168 max.

The Shelby splitter (top and bottom) make a big difference above 150 I am told. Friends of mine that have run with and without it have said the car behaves drastically differently with/without it. I've never driven above 140 without it so I can't personally say, but mine has never felt loose or light at all at any speed.

Testing on a track in Arizona on a hot day, the '13 500 reached 196 and the driver stated it could reach 200 with better conditions. I reached 191 on an uphill straight line with a heat-soaked stock blower in mine after about three miles of acceleration on a 90+ degree day. It'll get to 200mph. At 191 with the lower splitter attached I felt every single bump on that road. No floating around at all.

Yes, I was thinking that with the 3.73's the top end would be a little less...just got to wondering as I had a small stretch of back country road before getting back into town yesterday and so i nailed it and at 100+ it felt like it was pulling just as strong as when I started....backed off as I was getting too close to town.....

At Watkins Glen on the back straight I was just about hitting the rev limiter in 5th gear at indicates 143 mph. See the video below maybe 30 seconds in or so.
I doubt 6th gear would gain much speed over that since it's an overdrive gear

weekend run with Harry's Lap timer on Autobahn?
