Would be nice to get a thread going here on intake pluses harmonics, runner length tuning for RPM usage. IE: pipes software colorful waves showing harmonics going on in the intake manifolds. This got touched some at YB but it got lost. It works in conjuction with camshaft overlap timing and intake closing and exh opening. Dual purpose thread. And how covers up what so no one can see ????? you guessed it.

Also port and manifold runner correct air speeds. Port floor speeds.
Short turn shapes. Port bias. Manifold inboard and outer runner sizes.

Please do very interesting in port air speed like to know more about floor air speed how far away from floor to check 1/16@ are1/8" and speed around ssr
