Ever wonder if the STOCK WRX spoiler is really functional?

ok i missed a lot of stuff that went on in here. i will keep it pretty short and stay out of the details
first off, who here has experience in computational fluid dynamics?
thats what aerodynamics comes down to (in analyzing it that is)
the comment about the bullet being the most aerodynamic thing out there is bs. the reason is is shaped as it is because it needs a flat surface on the rear so the explosion has a surface applying its force to as it propels it out of the gun.
there was another comment about how f1 cars and stuff aren't very aerodynamic and stuff. another bs comment. go do some cfd on an f1 car. you will find out that the front end is designed to make the air naturally flow right over the tires causing little drag. it is true that the tires are one of the weaker parts of the cars aerodynamically (if thats a word)
i don't really have time to go into any detail now since i am at work, but i can always bust out my old textbooks when i get home and get into all the differential equations and whatnot that govern aero.

I looked at the link that Huck posted and didn't see any mention of station wagons. Did I miss something? You are right about station wagons leaving behind a lot of turbulance but I don't think that turbulance behind a car is as important as turbulance along the top or front surface. I'll still vote for the wagon. a hydrofoil is shaped like a wing because it is a wing. It's job is to provide lift. I'm afraid all this has nothing to do with the original question so I'll shut up.

No, the link didnt say anything about stationwagons....but it demonstrated how the air flowing off of the roof of a car (any car) gets pretty turbulent.....but then IF the trunk lid is high enough and long enough the air rejoins the main airstream behind the vehicle much more smoothly, as the surface of the trunk will reduce some of that turbulence.....this is the same effect of the air coming off the roof of a stationwagon....except the air doesnt have a trunklid or anything to smooth the airflow after it comes off the roof.
wrx ish - I dont have any experience with the actual mathematical equations....but I understand how aerodynamics work, plus a little research here and there helps out too....but like the Bernoulli's (SP?) effect....thats all pretty logical, and you dont really need to know the exact mathematical theories behind it, rather how they are applied to the shapes/sizes of objects that are meant to be used for different areas of aerodynamics. Although, I wouldn't mind seeing some of your really technical stuff....that always interests me.....there's always room for new knowledge.

Damn I'm to lazy to type my other thoughts ... =)
