I have begun building first version box cavity using good thick cardboard. I changed the design to a simpler box, like the one pictured in post #3. And I extended it to about 150mm instead of the 100mm size they tested. I'm skeptical this will produce results on its own that I'll be able to measure with my crude methods, but I'm willing to try it out. I'll finish it today and test it tomorrow using coasting on a hill nearby. I'll post results and photos sometime Sunday night or Monday.

[EDIT: AS OF TUESDAY (6/11) MORNING I HAVE BEEN UNABLE TO GET THE TIME DURING HOURS IN WHICH THE WEATHER CONDITIONS ON THE COURSE ARE APPROPRIATE. WEDNESDAY LOOKS GOOD. I'LL POST RESULTS AND PICS THEN.]

EDIT 2: WEATHER REPORT CHANGED (6/12) FROM LITTLE WIND TO 8-10MPH WIND ... MIGHT HAVE TO WAIT DAYS, JUDGING FROM WEATHER FORECASTING.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
