The 57 Packard supercharger manual states the pressure of a maximum of approximately 5 lbs at discharge throat with a drop of 1 to 1 1/2 lbs will occur at the carburetor therefore the pressure reading taken at manifold will be within the range of 3 to 4 lbs.
My personal experience is that you can feel the difference in the seat of pants when driving a supercharged versus a non supercharged engine. with everything else remaining the same in the car.

In theory, there is no difference between theory and practice. In practice, there always is.

FWIW, the new Edelbrock catalog just arrived yesterday. They have a 350" SBC crate engine which makes 435hp. Same engine with a 5# boost supercharger makes 507hp. This is a 16.5%hp increase, not 33.3%.
