150mph is the "gentleman's agreement" speed. If a car can do 150 chances are it can do 200.

I don't think this is true: drag increases with the square of velocity, so that's close to double the drag from 150 to 200, and I believe somewhere above 60/70 mph, aerodynamic drag starts to overtake road resistance as the main friction source, i.e. it takes significantly more horsepower to be able to do 200 than 150.
