Thanks Bill, don't think I've got a book in me, might have a chapter or two but not sure it would make an interesting read
Was sent this today, thought you'd like to see it.
3 prong forks at the top are sensors (temp. and pressure) they set the baseline pressure/temp values and all the other sensors which are located at every at each intersection point of the two lower lattice structure measure the same thing in each location. Big tear drop shroud houses all the sensors and data recording.
Looks like Ferrari are measuring the diffuser exit air, tyre wake inboard and outboard of the tyre.
Big unshrouded tyres create huge drag, anything to help manage the flow around them adds performance.
just lifting off the gas in an F1 car causes more braking g force at speed than if you stood on your road car brakes as hard as you could.
