HP loss?

Using the formula given with my f150 5.0 as the guinea pig at 10000 ft I will loose 108 HP. The formula is directly proportional so at 5000 ft I would loose 54 HP. Now 360 HP is the peak HP for the 5.0. If you look at it as a percentage 108 HP represents a 30% loss in hp, wow that seems like a lot.

Can anyone out there validate this formula???

Also, I would really like to hear About real life towing experiences in the mountains, particularly the going down hill part. How hard do you let your engine work at slowing you down? How careful do you have to be with your brakes so you don't overheat them?

Altitude affects performance, that is why the drag cars are always posting faster times at tracks near sea level. At sea level the air is denser and can burn the fuel more efficiently.
