Intake plenum and 911 throttle body

[jb92563]

In thinking about/visualizing the airflow, I had a thought and some more questions and ideas.

What is the orientation of the TB? does the throttle plate pivot about the vertical axis (like a door) or Horizontal like oven.

I'm 99% sure the plate must be oriented so that it pivots about the horizontal axis since the other option would be a serious problem for even distribution of airflow to the left and right intakes.

With the scenario of a partially closed throttle plate I am thinking that the airflow would benefit from an small induced spin to reduce the impact of stagnant air pockets that are not moving and would disrupt the smooth flow of air and cause turbulence. That means that the flow divider should also have a complementary twist to neatly divide the flow without blocking the imparted spin.

You could design some small short fins that stick out behind the TB to impart a gentle mild spin.

Of course that sort of minute detail might be hard to test because many iterations will be needed to determine the optimum fin angle/length and resulting improvements in performance.

But sometimes those kinds of innovations cause break-through's that along with a patent is what makes inventors stupidly rich.

We need a flow modeling App to try this out and speed the development.
