I hate to ask, but
what about the Dynamic Intake effect in the PP with a traditional log-type
manifold?
If you think about the meaning and function of the
Dynamic effect, you will see that it is mutually exclusive with the
traditional log-type manifold. the 'log' is a plenum chamber which
inherently damps out the dynamic waves and reflections in a DIE intake
system.
The timing, length, etc would be different than for the
sideport DIE setup that Ed Anderson did so much work on. I won't even
pretend to have any idea what the proper parameters are for a PP DIE
setup.

Tracy,
I was leaving work and didn't understand his question. I interpreted
it as ram tuning effect which is very possible using a log plenum, it just
depends on the inlet tubes. If you wanted to work out a manifold to use the DIE
it should be possible but you're right Tracy it wouldn't be a conventional log
manifold of course. But like dead reckoning I really dislike the name!
