When fogging, do I need to take this air box off completely or can I just undo the small hose shown in the middle of the picture that connects to the very large hose and spray it into the large hose from that opening ? Trying to bypass having to take this airbox off ...

I fog directly in cylinders by pulling the plugs.
 
My motors are naturally aspirated, so I’m not sure how much the supercharger restricts fluid flow. The key step is to remove the spark plugs at the end and spray directly into the cylinders. The idea is to coat the cylinder walls, since that’s the area most prone to corrosion, and protect them from rust caused by moisture. I do wish the water box/muffler had a drain—when the leftover water evaporates, some of that moisture could easily work its way back into the cylinders.


a few weeks exposed to open atmosphere / rian the oxidation build up is amazing

So if your car or truck is going to sit for 6 months would you fog it down? Completely unnecessary unless it was going to sit idle for years.
Your cylinders are not exposed to the atmosphere. What happened to that block is not going to happen to an engine in your boat or car.
I have disassembled engines in my loft that have been open for years with no rust on the cylinders
