I was looking at the new Mercury Marine 4.5L V6 intake manifold
and wondering what inspired the design.
The engine is 4.00X3.60".
Perhaps the stroke was not increased to 3.75 to keep intake velocity manageable.
In last month's Hot Rod magazine LT4 vs Hemi on the cover, a GM tech engineer
discussed the intake manifold with the supercharged engine.
When the intake velocity is transitioning from sub-sonic to supersonic,
would a sonic boom occur inside the intake manifolds on both of the above examples?
