Default RE: Formula one speeds

Simple arithmetic tells me that to achieve that speed at that rpm requires at least a 10.5" pitch prop. That is ignoring all of the inefficiencies associated with whirling propellers and the drag of the airframe. If those factors were added in at the generally accepted (Not totally accurate though) figure, the required prop pitch would be somewhere close to 12". Something does not add up here.

It is not that I am from Missouri or anything but.....................
