Paul,
Could I ask you and the group a question.
Question:  If I am going to use a turbo 13B with EFI is there any
advantage to a dynamic chamber for the intake manifold since it will
be pressurized from the turbo.  If there is no advantage then I would
like to design and build a very simple manifold with direct input to
the intake manifold from the turbo via the intercooler.  Appreciate
all comments from everyone and hope to hear from Bruce and Tracy on
this.

There appears to be an advantage to things like dynamic
chambers and tuned intakes with turbos. 
Paul Yaw could answer this best.

BTW Abel Ibarra thought enough of the idea to retain
the stock intake system (extrude honed) with his first
730 HP 13B. From what little I can see he is still using
it on his 800 HP 13B. I plan to have intakes pipes at
least 18 inches long with mine.
