One other point: Has anyone ever looked closely at the rear end of a Ferrari Testarossa? They appear solid from a distance, but up close they are almost entirely open to allow air to flow out. Here is a link to an image that shows it somewhat. . .

The lid is solid and the bumper is solid, but other than that the engine is completely open to the elements in the back. I always assumed it was to increase cooling as the air would come in the side vents, some for the intake (12 cylinder, OK a lot for the intake) and the rest would just bypass and cool off everything in the engine compartment.

on the mid-engine cars...
most of the vents from the sides that go directly into the engine bay (meaning not through a rad for oil or coolant - which many do) actually blow on the exhaust manifolds back. Since all the exhaust is in the engine bay, moving air across the exhaust and out the rear is key. Like any exoctic - if not moving the heat from the exhaust is a major issue in the engine bay.
They do not blow directly on the engine - since that would not be good in the rain or snow. However, cracking exhaust and manifold (especially on turboed cars where the exhaust gases are very hot and moving). My Lotus is a good example.
The challange with the front engined cars is that the airflow performance is reduced by a high-pressure zone that builds up in the engine bay, with the engine itself blocking the free flow through the rad.
the point being - anything you do to help airflow will improve things a bit, some more than others. Water is a major issue to manage. At the end of the day - it's more for looks than not - so that's the major part of the decision of where to place it and how.

I wanna keep my engine bay a bit cooler too, in fact Ive removed the plastic engine cover cause I guess it holds the heat a bit arround the coils, intake, injectors and what worries me the most is the plastic injectors plugs getting cracked whenever I need to unplug them, like tomorrow 
I'll replacing all 6 coils for brand new OEM's as those that came with the car are aftermarket crap, thats why they'r :q:q:q:qed already. Right now Im running 1 ford escape coil, and 1 v6 mustang coil.
Back to subject, I wanna open the hood too, I want 2 vents, EVO VI kind of but I want them to look flush.
How does EVOs deal with water issues???

I did some measuring and did some picture taking of my wiper cowl as I have it off for a possible repair of the coolant bottle or hoses.
Anyways, I took a good look and there is clearance inside the hood for good ventilation into the cowl. I have some vents I could use to make some custom little vents that fit flush. I think it is definitely possible and could be good for heat removal.
I am going to do an experiment while I have the cowl off and do a test drive and temperature taking while the cowl is removed (mimmick of having the vents); then do a drive with stock cowl in same conditions and take the temperature while driving.
I will use this data to see if it is even a difference that is worth the mod.
I ran the engine to normal operating temp while the car was sitting in the garage and with the cowl removed, I could feel the heat rising up out in front of the windshield. I think this is a good idea, but I want to see numbers before cutting into my cowl.
I will hopefully do this soon pending on how my coolant leak situation goes.
Here is a pic of where on the cowl is straight for possible ventilation. The squares would lead directly underneath the strut bar and on both sides of the engine block. I also used this time to inspect how the water is handled off the cowl and off the wiper holes. The corners of the cowl lead off into little ducts that spit the water and debris to the ground. And the wiper holes lead down little spouts that pour directly into the engine. So that right there tells you that a little water coming in from that area into the back of the engine would not be a big deal.
Also the vent design I had in mind would have a lip against the bottom side of the cowl where water pools up and runs either left or right that would prevent any water from just straight up draining into the engine bay.
The orange squares are roughly the straightest parts of the cowl surface.

thats cool man, i would like to see how it turns out, maybe in the winter it would be like a window defroster, haha but what kind of grille you gonna make to cover the holes so stuff doesnt go in and water too

I actually want to but mercedes style vents up near the top of the hood close to the cowl ....but I can't find any metal prefabs to weld in and plastic ones never look good. won't cowl vents blow too much hot air directly across the wind shield? (I am thinking of fogging issues,..)

use fog-X on the windsheild
and the heat would greatly help in winter too :-D

Yeah...? Or just cut the windshield out all together.
