small port is good for NA because of higher port velocity, big port is better for high boost, because it has imilar port velocity with that extra boost, but will not be great off boost...

for a given port cross section, there should be NO difference in intake velocity between boosted and NA applications. the same VOLUME of air goes through the port in the same given amount of time (ie velocity of the intake charges is the SAME), its just that the air in a boosted application is denser. there may be some effect of compression/decompression with chnges in velocity of the intake around corners though etc...

cheers
