In theory a turbocharged engine as used in Formula 1 should be immune to the performance loss suffered by a naturally aspirated engine at high altitudes because the turbo can simply turn faster to make the same boost as would be created by lower turbine speeds at sea level. A turbo engine’s combustion chambers should therefore not experience any difference in the oxygen content between low altitude or high.
