Highest recorded top speed of 3/S? Has anyone ever broke 200mph...

If you create a differential it will try and equalize itself.

True. But predicting where the lows and highs are, and how the flow gets from one to the other, turns out to be completely non-intuative and often works completely backwards from what is expected. More than one engineer has discovered his outflow vent working as an intake.

Not to mention the fun that comes from turbulant flow and vortex generators. Something that looks trivial - like maybe a windshield washer nozzle - might be in fact generating a vortex or upsetting flow farther down the car.

You can make general predictions with a reasonable degree of accuracy, but specific predictions about a specific part on a specific car require testing for validation.

Do I need to say that anyone attempting to drive 200 MPH on a public road is an idiot? Can we take that as a given?
