Question Regarding "boost"

[ak_stylez]

hey,

when people refer to how much boost they're running in a car, for example 7psi in a stock skyline.. is this a relative pressure reading? it cant be absolute right? atmospheric pressure is 101.325kN/m^2 which is just about equal to 1 bar... so if it were absolute that means the turbo would be working backwards (for cars running less than 1 bar)... right? which is nonsense obviously.

does a reading of 7psi mean 7 + atmospheric?

thanks

ah damn... i posted too soon. i just read in my notes that gauge pressure measures pressure differences from the atmosphere, so i was right.

thanks anyways everyone
