Steve,
The air entry to the carbs is quite critical and should ideally be smooth and
tapering
inwards from a larger diameter, which the Europa airbox more or less achieves.
Generally a 2 degree inward taper will help to preserve lamina flow in
the runner, as is often seen on the runners of injected engines.
This is further evidenced by the adverse impact on carburation that sharply
curved
SCAT tube and/or long parallel-sided runners has, such as on some Jabiru and
VW installations.
