[T3] A bit more...balance.

[Toby B <toby@wolfenet.com>]

You've got the idea, Toby,
	The only refinement might be that, as one cylinder is generating a
high-pressure shock wave, another has just started its intake cycle, and
has a low-pressure condition in its part of the manifold.  So the high
pressure shock wave is drawn and pushed towards the cylinder that's on
its intake, giving it a bit of a boost.  In theory, at least.  It's a
bigger deal in a V8...
	Think of it as the reverse of the scavanging that's happening in your
headers...

The real Toby said, pretty darn accurately:
Now, when air is drawn into the intake system
(be it carb or FI) it has momentum because it has mass It wants to
all travel into the cylinder BUT! when the valve closes, all the air
that
was drawn into the intake system and has not reached the cylinder is
still
wanting to move  With the valve closed, the air kind of
'bounces' off the valve and a shock wave 
<snip>
What the balance pipe does is give the shock wave more area to move.

Questions?  Class dismissed!
