Another fun fact about a Crossfire at high speeds... Can you name at least 4 parts of the car that have zero forward speed, even at that elusive 200 mph?
A 30 mph tailwind would ideally give you a 30mph top speed. I say ideally because anything other than a "rule of thumb" estimate in aerodynamics is a 3D euler field problem.
But sure, it would be accurate to say you get "about 30mph" more top speed. It would be even more accurate to say "it would take you about 30mph less worth of horsepower to get to the same speed" - a statement which allows you to ignore gearing.
