You can get....ie in your case you would need to make it, but you can get coolers that go between blower and engine. But being attached to the engine and of limited size, you're always fighting a losing battle.
Also, depending on throttle placement, adding lots of volume between throttle and intake valves can complicate matters further.
Your easiest bet probably would be water injection. In the UK Aquamist kits are probably the best and give you the option of controlling flow vs actual demand.
All of the yank kits do not offer this. The basically just control flow vs boost or some other factor, which often means you have more fluid injected than you need.
Inject the water pre-rotors would probably be the easiest option
That said, if that huge black box is all empty plenum, maybe you do have lots of room for a water/air unit. Although you will then need to route pipes, pump, front rad etc.
