Yesterday my brother and I were discussing fuel induction
systems and realized that neither of us understood the
function of the balance pipes found on so many of our
British cars. So I'm appealing to wisdom of the net,
especially those of you (Brian, Scott?) who undestand the
physics of air flow involved to help us out.
The question really is what does the balance pipe do? I know
that if it gets plugged the cars run really poorly, but
most other types of cars lack such devices. Are the balance
pipes there because of the (primarily British) use of
constant velocity carburators? I also know that when one
replaces SUs or Strombergs with Webers, the new manifolds
are of the indivual runner type without any balance pipes,
so that fits with our theory. Anyone know for sure, and
can explain what's going on to a biologist?
Thanks,
John
