The whole idea of Forced Induction is to cram more air into the cylinders than our natural 7 PSI atmosphere can push into the chamber in the time given. Superchargers and turbos do this by using power from the engine, may it be mechanically from a belt or using the exhaust... either way its directly related to engine speed... I'm just rambling, this isn't even part of my thought.
What if someone were to rig up a compressor into some cavity... which would pressurize a tank to something like 200 PSI, and were able to release it into the intake for a 'shot' of forced induction? not 200 PSI into the cyls, you would regulate it down to 3-40 PSI, whatever you can run... but kinda like Nitrous, but just air?
The problems I see:
-Your intake would need to be air tight (no problem, usually) and have a one way valve to stop your 'shot' from just firing backwards away from the engine back to the atmosphere.
-The ECU would have no idea how to handle a huge change like that in air. The MAF/VAF would max right out, and you would never get enough fuel... could this be corrected with Megasquirt?
-You would only want to do this a WOT, otherwise you might blow up your idle control...
The benefits:
-You could have a very small compressor that would fill the tank very slowly over time, may it be electric or belt driven, and when the tank is pressurized, you could have it on a shutoff. It wouldn't really sap power at all, never more than an AC or something.
-You could operate it only when you felt like it, like nitrous.
-No fuel to buy, aka NOS.
-Its unique

-You could probably rig up a pressure regulator in the cabin so you could choose your boost ammount.
-It could be any sized tank... you can cram a lot of air into small spaces.
