!? How so? WRT carb(s), CFM requirements can be handled by a large 1bbl, or
a smaller 1bbl / cylinder (this can be an oversimplification depending on
application, but valid for this comparison). It's the manifold that
primarily determines the power / torque curve and drivability
characteristics WRT a particular motor's design. A dual plane plenum
manifold has the best efficiency for street / amateur racing. Each cylinder
draws what it needs based on it's volumetric efficiency.
The other extreme is a single isolated carb / runner per cylinder that has
to be a tuned length for a fairly narrow rev band. Below or above the power
band, torque, efficiency falls off rapidly. So for street use, it has to be
tuned for the lower portion of the power band, with long runners to lower
the torque peak. This looks cool, but is very inefficient for a number of
reasons. If the runners are short as on a Cobra / Weber system, the torque
peak is right up there with the HP peak. The lack of low end torque is a
blessing with such a light car / forward weight distribution, but
efficiency suffers mightily (mileage / emissions).
!? What's the fact that it's a Wankel got to do with it? It has intakes to
suck in a fuel / air mixture that fills a chamber doesn't it? :^))
