Now I know a lot about engines, but I do not know a lot about engineering them. Sure I can fix them, figure out what part isn't doing it's job, clean them and bolt it all back together, but I haven't yet been able to build and design an engine from scratch. One day while looking at a friends Triumph Twin though, a thought occurred to me. If getting great air flow is a huge part of motor efficiency, why have the carburetors facing the opposite direction of the wind? If you were to theoretically place the carburetors where the exhaust ports are and vice versa for the exhaust, and then tune the bike for such an operation, wouldn't it vastly improve air flow? I mean, it would practically be turbocharging it? If someone could enlighten me as to why this would be tremendously stupid though, I would much appreciate it. Thanks!
