Re: [T3] Dual port manifolds and the balance pipe


On the same note , ignoring the  "Darkness" of such a question :
would a single carb be better ? what are the ups and downs of this setup
,besides no balancing problems ?
Just a thought

If you look at these patterns and consider how they repeat, you will
see that they look like V V _ _ V V _ _ V V _ _V V and the simplest
repeating unit is V V _ _ , which represents 4 strokes or 2
revolutions of the engine. But if I could get all 4 cylinders to suck
from the same manifold the pattern would be V V V V V ... for which
the simplest repeating unit is just V, which takes 1/4th as long.

Something that takes 1/4th as long has a frequency that is 4 times
higher and would be represented by shock pulses in the intake
manifold/carb that are 4 times closer together. This is just another
way of saying that the wavelength is 1/4th as long.
