? for people who are not running the hood vent louver
Honestly guys, we could debate this all day. We need to see wind tunnel data to get a real answer. the data is out there for the vortex generator ... maybe it's there for the hood vent as well?
the bump creates a low pressure, sucking the air from the fins from the vent.do you not understand the basics of how an aeroplane wing works?
the bump in front of hole creates a pressure field that pulls air out of the engine bay.
the ideas of air escaping and entering that some of you people are coming up with is hysterical.
Kaiten2 has said that the vent is to stop air going down into the hood and what is worse is that you agreed with him.
has anybody here taken basic physics?

reasons:
doesn't make extra drag for the car. Turbolence etc./imagine ,you blowing the air in the box/
Doesn't create lift./the air flow is not going under the car/
But most importantly: Because its not going in the engine bay, speeds up the out going air flow from the engine bay. How?
The engine bay is a high pressure area. Caused by the relative wind, wich is coming from the openings from the front of the car. Higher speed mean higher pressure in the engine bay. And the better is the airflow over the hood, makes less pressure there . So the difference between over the hood vs engine bay is higher= more airflow towards the low pressure area. If you remove the vent ,it will be turbulance there and worst, some air will even enter the engine bay ,making higher pressure ./mora drag./ The vent is there to regulate the airflow over the hood and the out going airflow from the engine bay. its not a rocket science, its common sense.

I didn't know something like this would get so technical, I took mine off just because I wanted to. I also thought it would help get a lot more heat out, but I live on an island so things are a little different here. Where I am going won't take longer than an hour so for me I guess it wouldn't matter so much. By the time the motor even got hot enough I am already in a parking lot watching the heat waves as I get out of the car. But that is just me on an island.

I'm lost as to why people keep debating this, as no one is going to be able to effectively explain the physics behind the functional design of the louvers (louvres) in this forum. It would take a "white paper", and most people here don't have the attention span to work through and comprehend the contents of the average white paper.
Removing the louvers will, at best, provide some additional heat dissipation while the vehicle is not in motion. The amount of heat dissipation will be negligible, as dangerous levels of heat are only going to occur while the engine RPMs are well above idle. If your car has heat issues at idle on even the hottest of days, then you have some serious problems and the presence / absence of the louvers should be the least of your concern. In general, if your car is sitting idle, it's already cooling off to a safe temperature.
The laws of physics are rarely measured or described visually, so those of you who claim to see more heat coming out of the engine bay have proved absolutely nothing with your optical analysis. (Hopefully) you are doing this while the vehicle is not in motion. Seeing more heat waves falls into the same category of visual cool factor as the absence of louvers (hey! I can see the motor!) and pretty much falls into the rice category. As stated above, your hood vent is most important when the vehicle is in motion, so focus on your driving, not how "balla" you look while you're chillin' next to your ride.
Laws of physics are best described in general terms on a car forum. In general, air flow is going to be more important than air volume when it comes to engine cooling. I say leave the details of the hood vent to the folks with the wind tunnel (Mitsu) and stick with the details that you can measure.
