Message	It's very hard to tell what effect an aerodynamic mod will have without testing it in a windtunnel. Something that seems like it would be more aerodynamic could actually be counterproductive. 240Z's are sleek and aerodynamic looking while VW Beetles look bloated and draggy. But the windtunnel says otherwise. You can't tell just by looking at them. The original poster, who wants to construct an air diffuser, is just as likely to hurt performance as he is to help If you saw a pointy cone, which way do you think it would cut through the air better, sharp end first or flat base first?
