lets say you are at 10,000', how much boost pressure would it take to compensate to have the same horsepower as if you were at sea level?
14.7psia is the Standard Atmosphere at sea level. Its 10.1psia at 10,000'. I kinda think it would be 4.6lbs boost to make up for it, but then I lean more toward any positive boost pressure and you are at or above sea level hp. Because NA engines work off vacuum right? So the minute you change from Vacuum to a positive pressure wouldn't you have made the necessary amount of boost to compensate?
I know its a silly question, but I got in an argument with a guy that said its 7lbs for every 5000 feet, and not I cannot stop wondering. Im kinda obsessive about understanding things. So if you could help me out.... Thanks
