At some point Charlie, the compression ratio limits your boost level that you can run with available fuel. You seem to be on a Max Boost quest.
The fact that you were running 35 psi with a 4 cylinder engine and had good durability and now assuming the same guidelines (except for fuel economy) what would be the benefit of going 3 full points higher in compression ratio with the same fuel, a V-8 engine, and twin turbos? And thinking that it would not have combustion stability issues with the higher static compression ratio. Corvettes tried that deal in production with direct injection and would up running very moderate boost because it was a street car.
