A study by somebody named Hussain Ali at a conference on aero at Coventry found that a 4" (100mm) rear box cavity could yield a modest gain. But a diffuser at a slight angle (2*) was also needed. I tested a box cavity, without the diffuser, and had inconclusive results: http://ecomodder.com/forum/showthrea...tml#post376489

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. 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.
