You are right on target Chrissi.  This is precisely what Mazda did in

the

normally aspirated rotary.  They call them exhaust splitters and you can

see

them in all 6 port engine exhaust ports.  They reduce exhaust impulse

energy

by 10 db.  That means it reduces the impulse energy to about 1/3 of what

it

is in the turbo engine.  Wish I had them in my engines :-(

Tracy,

Did your first engine (the one you were using when you made the manual) have
the exhaust splitters?
