regardless of how many cyl. are being fed and when, two open (or partially
open) 1.5" throats are breathing more air than one 32 mm throat. My testing
and swapping data is cold hard numbers. Facts are facts.
True or False???
prerequisites:
The fuel air mixture throughout the throttle range on both setups
are perfect (yeah right) but theoretically...
The DGV does not produce the same HP for the same throttle opening. The DGV
literally becomes a logarithmic pedal motion vs. the linear motion of the
dual SU's.
The DGV at any instant is producing a higher velocity which also produces a
higher pulse pressure of the air/fuel mix. Resonance of this intake pulse is
what can starve or flood and engine making it bog at any sudden throttle
opening ...at ANY speed.
The SU's are a constant depression type vs. the constant velocity type of
the Weber. This pulse is balanced by the motion of throttle piston. This is
why oil, vacuum leaks, and the springs in the dashpot are so important to
stable operation and why the balance tube in the intake exits at all.
