Before this gets out of Hand, maybe you should look at Cam's idea as a part of DOE, in which you can be more flexible in reacting on the results you get on the track and eliminating the risk of parts not working as the windtunnel or simulations suggested. They wouldn't be designing parts on the fly, but show up to the track with CAD files with different designs, all previously simulated, and do the correlation after one or two runs. If successful, they could print out the next, more agressive design and test it as well.
As for designing on the fly, a very gifted engineer (Adrian N. some say
) would be capable of actually making changes to an existing design in an emergency Situation (i.e. nothing works right), but even he would want to simulate first.
The tech is far from being usable, since the majority of the cars are made of CF, which needs a conclave - not very portable the last time I looked. But a new material could change that too.
