Rusty,
Well it's like this, in a single it's much simpler to have one inlet tube than two.
In a 4 port it's much simpler to have two inlet tubes than 4.
In a 6 port it's much simpler to have two than 6,
and it's not just the runners that are simpler, it's also individual butterflies, tube bending welding and the list goes on.
 
Believe me when I say I fully understand those opinions which influence you - but please also understand, I'm not of the same opinion!
 
The PP insert is SIMPLE, the flow IS direct - my preferred choice is direct exhaust and inlet. I understand the development issues and this may not be the solution for everyone. Both PL, Richard Sohn and Jerry (who has considerable expertise support) support my own theory - however there are differences of opinion on runner diameter. Jerry's advice supports my own theory - through considerable evaluation.
 
In my opinion both theories are correct, but for different applications. Both PL and Jerry are on the cusp of evaluating their individual developments - we will see what we will see.

I'd much rather have a P-Port and the simpler porting.
I'm P-P'ing the single with RX 8 rotor - for that very reason. George ( down under)

Hey George,
 
All in clean fun, how is it that you figure it's "simpler" to make your own p-port, and plug up the factory ports, than it is to just use the factory ports that are already there?   9000 rpm not enough for you?   Is this one of those "things are different down there" situations we read about in the Australian tourism ads   :-) 
 
Cheers,
Rusty (taunting the p-port boys again)
