David Vizard - Which to prioritize - PORT FLOW or PORT VELOCITY?
Here's a list of velocities don't know how accurate the description are, DVs in the video seem to run higher.
318 @ 5500 rpm head cfm need works out to be 214 cfm. Csa = cfm x 2.4 / fps
1.47" cas = 214 cfms x 2.4 / 350 fps too much velocity
1.65" cas = 214 cfms x 2.4 / 211 fps highest usable
1.80" cas = 214 cfms x 2.4 / 285 fps suppose to be ideal
2.28" cas = 214 cfms x 2.4 / 225 fps lowest usable
2.44" cas = 214 cfms x 2.4 / 210 fps too little
1.65" to 2.28" is a pretty big swing for a 214 cfm head.
