clock (someone or something) at speeds of (some amount)
To record someone or something traveling at a particular speed, as by using a radar gun. The officer said he clocked you at speeds of 70 miles an hour in an area where the posted speed limit is 35. They've clocked his slap shot at speeds of 80 miles per hour before, so I'd get out of the way if I were you!
