Kent, if I tell you I have to kill you!
However, I do have a concept for a 100+ mph human powered vehicle but can't get anyone interested in building it. Would be a great university project!
This shape was optimized analytically for the velocity/pressure distributions at the chosen speed range of 80~85 mph. [Laminar flow thingy!] Add 100, 200 or 300 mph and it all changes. The previous record holder was an "organic" design by a sculptor.

Now where did I put that weed-whacker engine and the model airplane fuel?
There was a CFD study done that "proved" that if the second place guy would have cut his ponytail he would have beat the "enhanced" Lance! About 9 grams of drag is considered the theoretical difference between first and second place - all other enhancements being equal!
