Default Intake Airflow Question

Lets look at 3 scenarios:

1) Large throttle body "funneling" down into a smaller sized intake port (kind of creating a nozzle effect)

2) Throttle body and head well matched with little change in cross sectional area

3) Small throttle body with a larger head port

Which one would you pick and why?

First 2 are fine, 3rd is useless and typically a waste of money.

1 will give the most HP and second broader torque assuming of course the parts used are optimized correctly for flow.

1 or 2,3 is basicly a trick question.#1 is fine as long as the t body isn't too big and the port too small and the port is matched to the runner (will still work,the port will just be a choke point) #2is pretty much what your looking for as long as everything is set to the rest of the build
