Well the boy racer in me says, hey that engine looks UBER-kewl.... but the engineer in me says: Er, that manifold seems to have three holes going IN, and only one hole coming OUT, so... er... apart from replacing one large carburettor with three small (and expensive) ones, what does it actually DO ?? (apart from looking cool, of course)
Would the same effect not be achieved simply by using a larger jet in a single carburettor?
Whilst it's true that you'll get greater volumetric flow (more air in = greater fuel loading = greater power) from three small tubes instead of one large one of equal total cross-sectional area, the fact that for the two outer carbs you take the air flow through two 90 degree bends within a few millimetres of each other, and then try to ram the whole lot back into a single tube (the inlet port) says to me that the benefits of multiple carbs will be completely balanced by the loss caused by the convoluted air flows and the massive restriction of the single final inlet port.
In other words, a huge amount of money and engineering work to achieve the square root of bu$$er all...
Or am I mising something?
