nicely put together, and spot-on in terms of everything I have heard/read from credible sources. My only question is the part of cutting the hole in in the upper radiator shroud for the intake. The air in that area is high pressure and ahead of the radiator. That makes it close to ambient temp and the high pressure will seek the low pressure of the air box. The radiator is seen as a restriction as far as air flow is concerned, so the opening for the intake is a good spot for it to go. No doubt opening it up will help that, but the air isn't stagnant or hot between the grille and radiator. After the radiator, the air is indeed hot since it just took heat away from the radiator. A number of race cars use the sealed area in front of the radiator to duct air to the intake or brakes (depending on the car), so that area is a good spot to pull air from.
I wish I had better data from wrapping the induction tubes, cold charge tube, and part of the airbox with gold foil. I started that before I got my Accessport and I also did it over time in the fall as ambient temps were dropping. The delta between charge temp and ambient did drop with everything wrapped, but I really needed a more controlled test of before and after in order to prove it worked. The cost of the gold foil wasn't bad and it just took time to get everything wrapped. It is another modification that doesn't produce power, but helps keep the charge temp lower and reduce heat soak.
Another low cost modification that I have done, but don't have any real data to back it up, was to seal off the sides of the intercooler to the bumper. Eventually I want to remove the bumper cover and seal everything between the intercooler and bumper. I took scrap strips of aluminum and double sided tape to create a barrier between the sides of the intercooler and the bumper cover. I also took heavy duty duct tape and sealed the plastic trim below the intercooler. Anything to help make sure all the available air goes thru the intercooler helps, either stock or aftermarket. I sealed up the radiator on my Mustang so well that the engine would run too cold on the street and I needed to undo a bunch of the shields.
