big engines do not care, (it starts with big air at 2 liters)...
little engines, the smoothing of channels, preventing surges (a calm cool source it can get on its own without changes) is a good way to go.
inlines have the intake danglng in the willywags, it makes it more sensitive, I learned this via my own boxer and inlines, I run both. the boxer needed a venturi, inlines don't care what the pipe is.
smooth for small is good.
