The Flow Illustrator website was briefly functional yesterday (it's been down with various errors as of late) and I used the opportunity to update my air flow tests for my 2003 Toyota Tacoma short bed truck to remove some noise from the slanted cap configuration and to add a new configuration: A cap that rises directly vertical 3 inches above the cab i.e. without a slant (or "wedge" in cap lingo). Best watched in 720p HD...
