Check out the HP calculator at www.superchargersonline.com


Under ideal conditions, you can expect to burn 6.802% more fuel and air per pound of boost. This is the starting point for this calculator, however, as boost rises above 5psi, other inefficiencies kick in, so gains above 5psi become progessively less effective in making more power.
