Now you are entering into fluid dynamics and molecular flow. remember my first statement, I'm not going into that portion. Once you start moving gasses then yes...there are many other factors that come into play. So I can see why the top one would interrupt. Look at it this way, the top one creates backwash of molecules that other molecules have to fight against to get in. That is a very simplified explanation...but if you've ever been to the beach.....a larger than normal wave hits the beach and water runs up the sand.....as that water is running back down the sand, another wave is trying to come in....but its power is offset by gravity pulling the first large wave back down the sand....therefore that 2nd wave just peters out.... Fluid dynamics starts the debate about how long the intake runners should be....why do you think that LT? intake is so funny looking? It is the length that it is because they want the valve to close....causing a backlash of flow....that backlash runs all the way back and hits the other side...in which case it is flowing the correct direction and a "Wave" now hits the valve just as it is opening.......forcing more gas and oxygen mix to enter the piston. Other tuners use the runners and tune them for this very phenom. Fluid dynamic engineers come up with these designs. |
