@siadam It's obviously going to be cooler, the issue I was more addressing was creating more drag and air resistance, and interupting the aerodynamic issue.

Also intake temps. Engine compartment temps will be cooler of course

 

Vented OEM hood is more show than function. Just an opinion.

If you are force inducted then the cutouts would be a cheap functional mod.

Probably more looks than function on a NA.

I do like the way it looks but It's not needed in my case. I like the 2 holes over the 3

 

hot air rises hence the air escapes from a vented hood making it functional.

 

Only at a stop. If the car is moving, the air goes wherever it wants.

This thread may have been linked above, but it has some good info about hood vents. Depending on aerodynamics, the placement of the vents is a huge factor in a vent's effectiveness. If the vent is in the wrong spot, it can totally screw things up, and cause air to flow the wrong way.

 

Is there a wrong way? Do I care if air flows into my engine compartment through the hood, vs. through the radiator, vs. up from the road?

For FI, my assumption is that any airflow is good. For NA, I might wonder more about impacts to aerodynamic drag and lift, but they're probably minimal on the street.

 

Yes, there are lots of wrong ways. You do NOT want air flowing IN unless it is through the radiator. Any air that flows into the engine compartment that does not flow through the radiator is reducing the flow of air through the radiator.

 

im still on the fence with this one.
