I have had my 2003 M45 up past 120mph and there was plenty of oomph left to go higher. On my 1991 Q45, I have had it up close to 145 to 150mph indicated - see thread on Infiniti Speeding stories! But, now that I have a young son (and it ain't worth getting killed), I am unlikely to go much past 120mph anymore - not at least till he goes off to college on his own.
As a friendly reminder:
1. Never, ever drive a car past 100 to 120mph on any tire that is not in optimal condition.
2. Always set the tire to 5 to 7 extra psi (above normal)- use about 42 to 44psi.
3. Never speed above 100mph on a tire that has had a puncture and now has an internal patch. This automatically derates the speed rating of the tire!
