Not a bad first cut. That is indeed the essence of the physics. The main missing factor in your calculation is the losses due to the tires. This would be in the neighborhood of 35-40 hp near top speed. Through simulation software I calculate the 6MT will peak out around 188. Don't forget the small effects of exact tire size (see Michelin website) and tire expansion.
