This is simply false. It depends a LOT on compressor efficiency and flow.
It is true that adding power, with forced induction or not, increases cylinder pressures and may damage internals. But you absolutely cannot say that that any amount of forced induction will automatically result in catastrophic failure of the engine; and you cannot say that 7psi from one compressor is equal to 7psi from another.
