Re: exhaust size

[ScottyCBoy@aol.com]

I read a HP book on turbo charging and it stated that the exhaust near the
turbo outlet must be as large as physically possible.  The reason being is
that as the gasses exit the turbo they are spinning and not traveling in a
linear fashion.  By having a large exit the exhaust gasses go from a spinning
mothion into a linear path rather quickly.  Exhaust gas that is spinning has
to travel a much greater distance, and thus takes more time to travvel the
same distance if it were moving in  a straight motion.  the book then states
that the exhaust pipe diameter can be reduced later in the exhaust system.

Just my .02 cents.  The explanation makes sence though..
