I'm no expert and please correct me if this is stated wrong.
The higher the bars (pressurized air) the more oxygen in the cylinder the greater the amount of gasoline that can be ignited. Without turbo the cylinders can have a maximum of X liters of air and x liters of gas, (lets say x = 1 unit). When you boost at 1 bar you now have 2 units of air so you have enough oxygen to combust with 2 units of gas. This all produces more HP with same size cylinder, otherwise you would need a larger cylinder to burn 2 units of gas.
So more you increase boost the more fuel you can pump into cylinder for combustion, that is until you start throwing rods and burning pistons.
