260 mph or so. the speedo does not go that high, but i am a good estimator of speed.
i kill me.
I wonder if GPS can keep up if you are going that fast. Our GPS displays speed. That would be one way to get a close guess.
A GPS can definitely keep up. Mine clocked me going around 500 mph at 15,000' on a 737. Getting it to lock onto 4 satellites through a tiny port hole is the hard part.

I thought I would respond on topic before we hear from the guy that flew his SR-71 blackbird at a ground speed of 2,000 plus mph. I saw my needle dropping from 120 after passing three gravel trucks that had been side-by-side blocking my path for an extended time. I downshifted my Shelby into 4th and made up the lost ground very quickly. I got off the throttle before encountering any other traffic going in my direction. This is the fastest I've ever driven. Since my car arrived with 5W-50, full-synthetic oil (the same weight/type used in the Ford GT) I assume there is no break-in required. Is anyone else concerned about breaking their engine in before attaining high speeds/engine revs?What's the top speed you've gotten your 2010 Mustang to??

I got my 2010 gt premium on October 10th and have 4k miles on it. So I'm def past the break in period. How many miles you have on your SHelby? That car must be very nice when you shift from 5th to 4th, the gt is very strong in 4th gear, as yours must be even stronger
I have never bought one supercharged so that would be a different story
My Shelby was delivered with an "Alternate Calibration." That's a feature that limits supercharger boost pressure and engine RPMs during initial driving. It's my belief that this was the result of a number of high performance and/or supercharged vehicles getting badly abused/damaged/totaled before delivery to the customer. As a result, my Shelby lacked performance the first few times I drove it.
Does/did anyone else require a wheel lug torque check at 500 miles?
