How fast have you had your 5.0 up too?

June 2010 Car and Driver says the 11 GT is (gov ltd) at 146mph


MPH
(3.73 gears) 1st 40
2nd 60
3rd 86
4th 110
5th 146
6th 146

Had mine up to 135 and still going strong. Had to let off, traffic coming up fast...

can someone do the math what the top speed would be with the 3.73's ungoverned.
