uh, oh - now we are gonna get into the age old supercharger v turbocharger debate! The thing with either of these methods is that you normally get a VE value greater than 1, i.e. forcing more air into the engine than it can suck in.
Remember though, that I am just using this as an approximate set of numbers to keep the carbs around their original operating range. You can flow as much air as the engine will pull, but with increased velocities and losses. To really show off I got some pretty graphs for later
