How about
: We are really strapped to a dyno and wouldn't dream of doing something so stupid on a highway.
The rpm vs speedo would suggest that you'd have to be in 6th gear. Which is too tall to go that fast. Have to use 5th for a top speed run. I am going to assume you switched the speedo to Kph and you are in 4th gear.
Save that stuff for the track. If you say, we can't go that fast on the track just step it up a notch or two exiting T9 and don't brake so early for T1
