...........Do I think that this concept is practically applicable? Given the right conditions, priorities and restrictions yes I do. Do I think that those will ever arise? No, I don't.
It was a good question because it forces us to think and challenge dormant assumptions that lay hidden in our minds.

One thing I learned going from scaled model experiments to full scale experiments is that the time, money and consequences also get scaled up.

Yea, I'd imagine that losing at Bonneville isn't a pleasant experience should one survive.

I don't think that has been mentioned in this thread.
Good point, not to mention the suspension is designed around certain sprung and unsprung weights that once altered could lead to mishap.

In another thread sometime ago someone mentioned the tires actually grow a bit in height as the rotational momentum stretches out the sidewalls at high revolutions. Kind of like dragster slicks that start out partially flattened and become doughnut like once the green light flashes.

Also in another recent thread someone mentioned the suspension at speed may be forced downward or upward depending on lift and or down-force, which in turn affects the CdA.

FREEBEARD, the doughnut shaped things you mention are 2 foot and not 4 foot and called tires?

You lost me buddy, please clarify for those that just woke up and the coffee hasn't kicked in yet.
