I've seen pictures of S2000s with Oddysey foglights. They cover up the fake air vents on the AP1s. How does this effect aerodynamics? Negatively because air isn't able to get through the bumper, or positive because the front end is smoother?

 

so which would work better to put out this forest fire? should I pee on it, or just dump my water bottle over it.

 

Not enough to have a significant effect at highway speeds. Aerodynamics really don't come into play until 70+ mph.

Even if you filled in the fake air vents to make them flush with the bumper, there would be little to no change in the front end aerodynamics. Because air cannot travel through the vent area (it's closed), it acts like the vent is not even there. Before and after results of closing in the space will look almost identical.

If someone really wants to improve the S2000 aerodynamics, they should make a full length flat underbody tray. Could probably save 3-5 mpg on the highway. Integrate that with a well designed front and rear diffuser...might actually get some downforce out of the package.

 

Ehhh, use the whole bottle.

Air isn't flowing through that part of the bumper anyway, hence why it is called the fake air vent. But to answer your question I would guess it has almost zero affect.


^Man, I need to learn to type faster. Beat to it again.

 

I realize that the effect would be almost 0, but from a theoretical standpoint, would that minimal effect be positive or negative?

 

Well I guess theorectically speaking it would have to have a positive one. I can't see how making something smoother would have a negative affect. Although I don't think filling in the vents would look good if you were thinking about having them filled.

 

Yeah, what everyone else said.

Theoretically, any performance benefits to be had as a result of your newly discovered aerodynamics will be negated by the additional weight of your foglamps.

 

 

I would use the water bottle. Less chance of burning your.......self.

 

An exagerated example...

Smooth ball versus a heavily notched ball. Note how the velocity magnitude fields are very similar. The separation zone behind the ball is almost identical. The additional pressure build-up due to the notch limits the development of the velocity profile slightly. Essentially, it is an additional separation region, which will cause slightly higher pressure.

The notched ball is experiencing about 7.3% more drag in this example.
