hmmm...i htink he's just looking at pressure wrong (this is just how i view it, and it makes sense to me, but maybe this is what they've been saying all along).

Pressure is techinically, in a sense the same as density, except it's not one solid material, but a gass with in a solid container. so if you have a a container that's volume is 130 cm3, (say 1g = 1 cm3) and you put 260g of gas in there, because of gas's properties, it's giong to squish up and compress, which is pressure. now that is just in basic phsyics clas (please correct if i'm wrong here)

now..when talking about super charges, i tend to look at PSI as more of an indirect measurement of flow. the s/c has a 130 cm3 volume (for exapmle of course) the faster the fan spins the more mass will be introduced into that volume there for creating more pressure. now when a gas compresses it has a tendency to want to expand, which it can't really do, so it heads as quickly as it can (or at a velocity proportional to the need to expand from the compressed air) for the area with the less resitance, which would be the exhaust port of the s/c (as in the hole that connects to the manifold). Now, this also means (in concern with the volume) the larger the volume the more mass needed to create a certain amount of pressure. now i'm sorry if this seems it's all just being slapped together, which it is, so if one of the wiser ones wishes to fix this go ahead. SO, if you want you're larger s/c to achieve, say, 5 psi it needs more mass of gas, or volume that's the word the rest of you hvae used for it so after this i'll stick with that, in order to achieve that (dur), which means it will be pushing more air at 5 PSI than the smaller volume s/c would be pushin at 5 PSI.

ADD CORRECT AND REARRANGE AS YOU WISH, but stop with the uber techincal, and mathematical parts, make it sweet and blunt, like you're explainging it to a 13 year old, less confusin that way
