Thanks, PNATERA1580! If DOES200 has a belly pan, now we know why and what it's for and how it does what it's supposed to do.The most cost efficient, scientific/engineering way to measure what kind of results a ground effects underbody tray does is with one of these meters:

http://www.racepak.com/ about $800
Jim, you must have an interest in this ground effects stuff, 25 years on the track and all. If you go ahead and start experimenting and measuring results, will you please post too? Thanks.
You can skip reading this Off Topic Note if you've finished your taxes already. [[Side note to explain the reason I keep jumping on the web: Guys, I'd rather do anything than compile my taxes. I've got a stack of receipts in a folder 3" high that have to go into a Schedule SE. It's like writing a term paper every year for me, and I cloister myself inside like a monk until I get it done, then I can officially begin Springtime! I'm going to take a nap instead and see if I can force myself to do that task later. Anything but that.... So much energy I channel into avoiding that every year.... Yuk! There's got to be something else I can do to "productively" avoid doing my task-at-hand, Yuk! Please ask some question or post a new topic or something.... But I can save enough by doing it myself to offset the cost of going to the 2005 PCNC Vegas Track Event, so I'll Nike, and 'just do it'. I always feel much better when I get that gorilla off my back every year. Their paid, but the forms, man that's a cumbersome task, I hate it. I'd rather gripe about doing it than do it. OK, adios then.]]
