Actually, a maximum of 56 1/2" of boost at full power off the carrier rings a bell, and that was on 'purple' 115-145 octane fuel. When purple fuel became scarce they were run on 'green' fuel, with a corresponding reduction in max allowable MAP.
They were never intentionally overboosted, as our lives depended on looking after our engines!
