Yep, boost is the amount of extra pressure so any forced induction engine has it. My car runs 4.5psi right now with the Kleemann S/C, but I have a pulley to bump that up. One interesting thing about a S/C is that as you make the engine more efficient (cams, headers, etc) your boost actually goes down. A turbo will stay at the same boost level unless it is at it's limit.
