Looking at specifics for 7000 feet, normal temperature and humidity, Actually
the loss with a naturally aspirated engine will be about 58 hp or 15.4 percent power loss. Forced induction engines will lose approximately 8 percent (27.2 HP) to 10 percent (34 hP) at the same altitude in the same conditions. The issue with forced induction is that the air at higher altitudes is thinner and the same problems that beset the naturally aspirated engines start to befall the FI engines as altitudes rise. Reduce the humidity, increase the temperature and the problem continues to increase. One solution is increasing boost which LR does not give one the option to do out of the gate. If you could increase injector output and sequentially increase boost to compensate for altitude, you theoretically could output close to the same HP as at sea level. (If the engine would stand the strain)
Turbo charging leaves the same issues but to a slightly smaller scale since they are already dealing with intense heat that must be cooled. Both supercharging and turbocharging inter coolers remain somewhat inefficient as elevations rise. Nothing performs like at sea level!
