    sure they have but in a typical v outboard the chest is where I guess its lost as thats not the optimal design when you look at other multi cyl 2 strokes
    The Late Dr Blair did lots of study trying to measure the pressure waves in an engine Do you have his books?
    One shows a photo of about 50 pressure sensors in a row along the exhaust.
    Add that to a high speed datalogger and more pressure sensors in the engine and you get some info on what is happening

    I can't think of anyone with more to gain or money to spend than Mother Mercury herself . The 280 tuner is at the top of the heap and if you follow Dr. Blair's numbers , you will see that from the center cylinders exhaust port sleeve to the transition (adapter plate ) from rectangle to oval is the correct length for a header pipe . And the cone follows taper and length for a proper sized diffuser .
    Like I said , Fonzi era mentality , where you are forced to pick the center two holes as a bull's-eye and let the top and bottom be your "fliers" .
    I have always been more of a Jennings fan than Blair , only for the simple reason that Jennings is more practical , while Blair is more computational ...

    I wonder what is lost doing the transitions from the chest to rectangular then back to oval like the port?

    Actually that fits right in to the subject .... since ya hafta break some egg's to make an omelet ...

    AZ sez :
    Theory to Practice...both have their place.
    Theory is good to keep from repeating the same mistakes over and over again . It can also be a guide down a bumpy road . However way to many get stuck in this phase (tech-lock) and never accomplish anything of their own .

    The difference between theory and reality ....

    A young boy asks his father what the difference is between the two .
    The father says I'm glad you asked , follow me and listen .

    The man ask's his wife , honey , would you sleep with Brad Pitt for 10 million dollars ?
    The wife responds , well honey , we could use the money ... so , yes I would .

    Next he asks his daughter the same thing , she quickly answers , Ohh yes , in a heartbeat .

    Then he asks his eldest son the same question .. the older boy says , that's a lot of money , yes I would .

    The father turn , looks at his youngest and says ... you see son ......
    In theory , we are multi millionaires .
    In reality , we live with two hoe's a *** ... see the difference ..
