Port and Polishing for heads, intake and exhaust-new pics

Steve's got it pretty right about the dimples.

They will force the boundary layer to be turbulent. This adds engergy to the boundary layer and allows it to stay attached under heavy negative pressure gradients. This all comes at the cost of greatly increased skin friction.

While there is a lot of vorticity, swirling air that helps atomization/dispersion, in a turbulent boundary layer it is confined to a very small portion of the intake tract. It would be more benificial to introduce vorticity directly into the main airflow.

I would really like to see Endyn has done.

Like a Tornado intake?

Hehe yeah, but only in the last couple inches of the intact tract. So we would want stubby tornadoes .
