Intake Air Question

[rreinicherr]

Is it better to have more air or faster air flow into the intake? I have always wondered what the rule of thumb is????

THANKS!

Superchargers and Turbos work by compressing the air (PSI). When air is compressed, more of it fits in a given space.

The speed of the air flow is important only in that it keeps up with the demand. Speed also helps to influence the compression.

I think....

In the early 70s when auto manufacturers didn't know how to produce power AND meet emissions, the aftermarket stepped in with some small port (high velocity) intake manifolds. Edelbrock had one called an SP2P. They operated well up to a certain r.p.m. and then became a restriction for w.o.t. use. They were supposed to be more for low(er) end torque instead of high r.p.m. horsepower (popular in the truck market). Offenhauser had their Dual-Port "360" manifold which had small "primary" passages and bigger "secondary" passages cast into the same manifold, which tried to have the best of both worlds.
Larger ports, slower movement, small, faster..you get the picture...

Sorry, no easy answer here; I guess it depends on what someone is after.
