Oops! Must've Oh well, it amounts to probably another 67 horsepower (45 percent of 150). Not likely without a turbo or nitrous.

square root of ((170x170)x 1.77)= 226
I looked at the video-- he appeared to be in sixth gear at about 11,100 rpm. I think we could figure out his real speed based on gear ratios, provided of course his sprockets and gearing are stock.
You would also have to account for the increasing tire size due to the additional speed.
