Even with nearly 3000 CFM of air being rammed in by the supercharger on
overdrive, the fuel mixture is compressed into nearly-solid form before
ignition. Cylinders run on the verge of hydraulic lock.

To make nitrogen into a solid, you need more than 50 gigapascal pressure. That would be 7.25 million psi...

near-solid form in this case means REALYL damn close to vapor lock.

Since the fuel doesn't compress, a huge portion of the chamber is filled with liquid fuel why a very small high pressure bubble of air sits on top.
