Are there any advantages or disadvantages to using short intake manifolds for dual webers?

Short manifolds are a Very Very Good Thing for the VW 411/412 and anyone putting a Type IV into a Type III body. Because even "baby Webers" don't hardly fit with regular manifolds.
In general, short and fat pipes have a greater flow capacity than skinny narrow pipes. But at lower flow rates, the short and fat pipes have worse velocity. So the shorter manifolds could help top-end power at the expense of mid-range torque and mixture quality. Depending on lots of other factors, of course. --DD |
