CFM, velocity and port size are not akways interrelated.
I’ve said the before and I’ll say it again. More than once I flowed heads on my bench, fixed them and showed LESS flow and amazingly the engine made more power on the dyno and was quicker and faster in the car.
Don’t think I didn’t have a **** of a time trying to combine the guy his heads flowed less and made more power.
Let me guess you made more power by improving the burn and used more of the air it actually ingested instead of just passing it through? Or better yet you improved cylinder fill increasing the trapped charge leading to greater BMEP?
