Thanks guys. Basjoos, you're making me quite brave about a small radiator opening--I have less than half your horsepower, I doubt I'll get burned (or boiled) with half as big a radiator opening. Bicycle Bob, that's an interesting thought--I understand how ground effect cars make downforce, but don't see how (or even if) they reduce drag...I'll look into that. And Christ, that would clearly reduce drag (I think so, but I don't always think clearly...like does the rear wheel 'draft' the front wheel in the traditional layout?) but it would be a major undertaking and would reduce roll resistance. So I'm not going to do that on the first pass, but I won't throw away the parts I cut out in case I want to make front skirts later--if I get, say, 98 mpg with wheels exposed and skirting the front wheels will reduce drag by 3%, it would be worth the trouble to get the car into the three digit club.
