WebFor normally aspirated piston engines, maximum continuous power output is typically 75% of the maximum rated power; most piston engines will maintain this power output until approximately 7,000 feet to 9,000 feet pressure altitude. Turbocharging can improve this altitude up into the teens, or even the lower flight levels. WebJul 29, 2024 · As altitude increases, the air density decreases, which results in a roughly proportional decrease in the horsepower your engine is able to produce. For example, a normally aspirated diesel engine might have 10% less power available at 800 m/2600 ft and 20% at 1600 m/5200 ft, when compared to operation at sea level.

It is approximately 1 inch for every 1,000 feet of altitude. And that calculates to around 3 to 4 horsepower lost for every 1,000 feet gained. Remember, power is inversely proportionate to altitude gained. Increased altitude comes with a price - loss of power. clear renewable

"WebAt 4,000 feet density altitude, 75 percent power, and a full-rich mixture, the engine burns 11.9 gallons per hour (gph). By leaning to best economy, this power setting's fuel flow drops to 9.7 gph. We get the same airspeed but burn 2.2 gph less. This not only saves money (we don't have to pay for the higher fuel burn), it is safer. " - Horsepower reduction at altitude
