Unless you are running it like a two stroke with cylinder ports and crankcase pumping, you would need a supercharger (positive displacement). this would not be difficult to do, but the problem would lie in the energy density, or rather the heat that would build up having 2 times as many firings per X rpm. Not saying impossible, that is for sure.
