Yep, that's the one I remember, in fact if you scroll down a bit in the comments on YouTube you can see where I'm mentioning that this is totally possible for a Carpenter Rocket. Way too much controversy over that video though. I like this one with the Diavel much better as it shows the POV from the Rocket including a shot at the speedo.
As for the rest of 5252rpm's videos, ya, he's beating up on a bunch of stuff but how fast is he really going and how long did it take him to get there? We can't tell. The video quality is horrible and there's no shot of the speedo. The only redeeming quality of the Hayabusa video is the speed reference from the Hayabusa speedo (which again, you know is reading high).
