You're absolutely correct... I guess I got sidetracked at work and didn't watch the whole thing

I have it paused right now and what I *clearly* see is:

Speedo has an exterior ring of numbers in MPH and an interior ring in KPH.
I've paused it where it's very clear and it shows ~142 MPH (~225 KPH) -- this is not the top speed attained, but just where it's really clear.

The big numbers on the outside are definately in MPH.

 

that thing must have a ton of $ into it to be able to have a possible (off the speedo) top speed of over 200mph... look @ time 1:55ish (pause) to 1:57ish (pause again) doesn't take too much to see it should run 200mph near or @ redline... look out v10 por-ch-a, here comes da stang... this is assuming that the speedo isn't wacked... one word... daaaaaaaaaaam...
