Bill, great car and great effort.
I'm not bold enough to say that I know how to cool a 1,000hp drag car. However I have spent a lot of research, time and fabrication on how to cool a turbo charged roadracing car. One of the items that I believe you may want to investigate is how to direct and pressurize the air going through your various coolers. You've spent time addressing how the air comes out of the radiator, but there doesn't appear to be the effort (that I firmly believe is necessary) to duct, seal and condition the air in front of the coolers and radiator.
There are a number of NACA research papers that are relevant. And applying the information has been very productive for my application.
Additionally, you need to address how the air that has flowed through your coolers can exit the engine compartment. I work on the basis that I need to have as many inches of evacuation available as there are inches of radiator. Whether that means properly venting the hood (no, that does not mean an opening at the base of the windshield which is a high pressure region), or vents through the fenders or rear of the wheel wells.
If my thoughts are of interest, I can post some pictures of our ducting, and I can dig up the NACA information. Suffice it to say that our methods caused the dyno operator that certed our hp/tq to comment that our car was unusual for the series that we compete in as it did not overheat. Our problem was trying to keep the car up to operating temp as it overcooled. And this is with a big ass intercooler in front of and sealed to the radiator front surface.
I am concerned that some of the thoughts about separating cooling components are in fact detrimental. Think about what you want the air to do, and how to keep it from swirling, escaping and bleeding off pressure.
Clearly you have to work within the packaging constraints that you have. But you'd be amazed at the impact if your thought process encompasses the air travel from the moment it enters your system to the moment it exits. That is...from in front of the grill (or it could be a bottom feeder) to the moment it re-enters the atmospheric air stream.
I look forward to following your progress.
