Actually gotta disagree strongly w/ you about bring fresh air in vs. letting heat out. A number of us down in FL have done this mod, and it makes a tremendous difference. My coolant temps dropped around 40F. I'm running a pretty serious turbo setup, so that helps a bunch.
Also as to people worrying about the engine bay getting wet; it's really a non-issue. Now, I don't like to drive in the rain b/c a) i have no traction and b) i don't like having to repolish my engine bay; but i've been in some very serious downpoars w/ both sides vented and had zero issues.

I would imagine bringing more fresh and colder air into the engine bay would do a better trick of cooling the coolant temperature and everything else than letting the heat out.
It's like letting a hot towel sit to be cool vs blowing cold air in it to cool.
by the way, JCA, how are you liking that inline pro kit?
have you got your 1/4 time yet? how does it handle? I'm looking into it, since any bolt on i get wont even equal to 80whp without spending a small fortune on engine mods.

Trust me, it's not cool air coming in At idle you can hold your hand over the rearmost vents and the air will almost burn it. Ask around in the FL forums as a bunch of us have done this mod. Everyone will confirm that it's letting a ton of heat out.
As far as the inline kit, overall i'm pretty happy w/ it. You'll not make nearly the hp/psi as w/ say the lovefab kit, but you won't be cracking your manifold either. I have had problems w/ studs backing out of the downpipe and turbo mounts, but inline has solved that issue so all is good.

For hot air to be coming out cool air has got to be coming in from somewhere
Hot air rise under atmospheric conditions so stood still the hot air will pile out the top.
On the move I guess air pressure over the bonnet could force cool air in the vent, it just means the hot air will escape elsewhere.

If the car is moving, there will be low pressure on top of the hood and high pressure in the grille, so air will naturally circulate that way.
It probably has the effect of increasing aero drag, but it's not like the S2000 is aerodynamically clean anyway.
