Looking at various s2000 "top speed" videos, the below looks like it may have been filmed on a dyno (check objects seen thru windshield at the end). Raises some quesions about "speedo only" videos.

Lmao definately on a dyno, you could see the hood propped open and nothings moving. Kinda dumb on his part, and it was also in kilometers per hour.

Ive also seen instances where people jack up the rear/front tires depending on what car it is and get some crazy acceleration videos that only show the tach.

FAIL.

 

no, the speed in is km/h
