I've done the same; there are not too many truly new ideas . It might be made to work in drag racing, used like N2O, but dive cylinder type pressures are still required to get a reasonable mass of air.

Using the stored air for supercharging has been tried. There are a couple of SAE papers on it (written in the '50's?).

The initial variant used an air ejector above the carburettor to provide the compressed air. (You've probably seen an air ejector if you've watched an F1 race; they're the short tubes connected to airlines they use to cool the drivers.)

The later version used additional poppet valves in the cylinder head to inject the high pressure air directly into the cylinder, after the normal inlet valve had closed.

The idea was to use a downsized engine and save some fuel when the extra power wasn't being used.

An auxiliary compressor was attached to the engine and a (large) high pressure storage tank installed in the trunk.
