many years ago, this company ...
http://www.ipdusa.com/

had a 'vortex generator' that attached to the roof with adhesives, and
was based on some NACA ducting (in reverse). it caused the airflow to
lift from the car body, effectively making the car longer
aerodynamically. or something. anyway, the claims were that it kept
the rear of the car cleaner and you got better mpg.

anybody in portland, OR, that could check and see if these folks still
had any of those 'vortex generators' left laying around?  i don't see
it listed on their web page.

this is what it looked like, except molded into all one continuous
piece ... the one in this picture appear to be a group of individual
generators.

or buy them in the u.s. and australia ....
http://www.airtab.com/en/
http://www.buyairtab.com/
scroll down some ... they are $2.75 each in singles.
unfortunately, a buy of one trailer kit (80 generators) for $220 works
out to the same price. :(

hmmm. the australian url gets an error ... but it is this main page
http://www.trucknbus.com.au/
and the Parts click also gets the same error. :(
