Some say that dual ZS are sufficient until I run over 5000 rpm for over
one minute, because that is where I will run into fuel starvation with
dual ZS. Some say triple ZS will add to performance at any RPM.
What is it about PI that provides a performance increase over
carburetion?
Is it a case where a theoretically very small carburetor could never
provide enough fuel air mixture to a theoretically very large engine
without running too rich -- I assume running too rich means that the
fuel is not being atomized or vaporized correctly? On the other hand, a
theoretically very large carburetor could not provide correctly mixed
fuel/air to a theoretically very small engine because the theoretically
very small engine can not produce enough air flow to make the
theoretically very large carburetor work correctly?
Hmmm.... Is that it? There has to be a balance between the "size" of the
carburetor and the "size" of the engine for things to work correctly?
And even when working correctly (the best it can work), the carburetor,
by its nature, still can not generate as much correctly mixed fuel/air
as can the PI?
If this is the case, then were does triple ZS fall in the scheme of
things -- on a scale of 1-10, where 1 is dual ZS and 10 is PI? Maybe
the answer is at low RPM triple ZS is at a 2 and at high RPM triple ZS
is at 7?
Thanks,
