You mean theories like using the airflow you get to make power?
How did these guys manage that I wonder:

Imagine making 2.2 HP for every CFM the head flows...........430 HP from 316 cubes. Some one should have told these idiots they needed to make the heads bigger not smaller.
All that power from a 145 cc port...........Don't these guys know the experts here know more because they've broken more parts.......Que the but but butters.
Imagine a shitty tiny port making power.........Nah that can't be done. Rumble was right very early in the thread 220 cfm x 2 = 440 HP.
