You have to be very careful how you modify everything in regards to air flow. You are going to modify the entire front end which changes all the air flow patterns in which Ford intended, which means all the pressure points they considered in the design are gone, and opening the hood up top could end up with no pressure differential across your IC and rad therefore no cooling. Contrary to popular belief, the Ford engineers knew what they where doing, and they created a car with a very low drag coefficient, that your going to lose out on flattening up the nose section like you are suggesting.
You have to maintain a high pressure zone in front of the rad support, and a low pressure zone behind the rad so air flows.
Frankly, your going to way too much work, and creating a safety issue for youself to boot (I shudder to think what'll happen to you and the person you hit in a front end collision). I've installed a delta fin IC that has a 12x24x3 core that flows across the way so I bring the heated air to the pax side, flow it into the IC and and the cooled air from the drivers side goes back up. I am running the MPX blower which has 350F+ outlet temps and I'm only seeing about 40F increase above start temps when I run the car hard continuously (way more than 1/4 mile sprints).
Datalogs and calculations are showing the IC to be about 83% efficient and I'm only seeing a 0.3psi drop between the supercharger and the intake plenum caused by the plumbing and the IC and that is with running 2.5" tubing. This is in a car capable of mid 12sec 1/4's.
I've still got my front bumper etc, and my IC is mounted off of that instead of against the rad. I have no coolant temperature issues and I still have a/c in the car. Having the bumper there is actually beneficial because it will create turbulence right in front of the IC which slows the incoming air down which increases pressure in front of it. I would dare to say, that I would not see much more cooling effect having that IC totally open to the front of the car. At this point more than 85% of the IC is directly open to incoming air, and the rest of it is being fed through pressure differential. I'm also running the MP chin spoiler in its original location which deflects air up into the rad etc behind the IC, and because it is high velocity air, its at a low pressure state which helps the lower IC by drawing more air through it. I'm also running alcohol injection so that will take care of any residual temps the IC doesn't get, and I get a big boost in octane while I'm at it.... I run the car on 91 octane all the time, and I'm running 26deg of timing to boot.
You have to remember with an air-to-air IC the closer the incoming temperature is to ambient, the harder it is for the IC to remove heat, and that rises exponentially the closer it gets to ambient. In other words, the hotter the air over ambient is coming into the IC, the more efficient the IC becomes. The best you can ever hope for with the ultimate and perfect setup (not possible in our cars) due to in-effencies is within about 20-25 degrees of ambient. Want better than that you need to run water-to-air IC.
I can build and install my IC setup in a day, and my car is still stock looking
