Let’s have another discussion. This time TrickFlow heads.

Theoretical question. Bench racing, you could say.

Without dyno testing or track testing, what do you guys "think" that vain may do to the column air coming through there? Would it redirect the air from cylinder wall side of the port (left side of PRH's picture) back toward the opposite side of the valve where it's less restricted by the cylinder wall? Would it try to keep the air from the other side of the port (right side of PRH's picture) from going toward the side of the port that is close to the cylinder wall (left side of PRH's picture)?
