I must say, I see one very good answer regarding pressure fronts. Vacuum is cause by nature and pressure (atmospheric) whereas suction could almost be considered artificial (I don't feel like checking it out now anyway). Why else would space be called a Vacuum. This is the basis on which non pressurized motors are refered to as being Naturally Aspirated. Becuase it is the pressure (14.7lbs to be exact) of Nature that fills the chambers. Intake restriction is what limits how well the chambers are filled (called Volumentric Efficiency-VE) for you No0bs). The artificial suction produced by turbos to draw in air to bring into the cylinders is what makes engines operate over VE. This is the reason a 2L@15lbs can make the power of a 4Liter+ NA, or why at twice the atmospheric pressure our motors make almost twice the power, of course there are other variables but this is consistant with it's understanding. A variable I've become infatuated with (Yes parts of my motor I'd have wet dreams over) as of late is the Camshaft which can use dramatic overlap and duration to create blow threw to slam air into the combustion chamber when the valves close, packing in that extra bit of O2. Other things which aren't mainstream yet are sound waves used on tuned intake manifolds which can produce more power with the proper length or tuned headers helps exhaust pulses from running into eachother and exiting the engine quickly and *efficiently* (quicker velocity leads to better chamber filling hence VE)
