Rusty,
Well it's like this, in a single it's = much simpler=20 to have one inlet tube than two.
In a 4 port it's much simpler to have = two inlet=20 tubes than 4.
In a 6 port it's much simpler to have = two than=20 6,
and it's not just the runners that are = simpler,=20 it's also individual butterflies, tube bending welding and the list goes = on.
 
Believe me when I say I fully = understand those=20 opinions which influence you - but please also understand, I'm not of = the same=20 opinion!
 
The PP insert is SIMPLE, the flow IS = direct - my=20 preferred choice is direct exhaust and inlet. I understand the = development=20 issues and this may not be the solution for everyone. Both PL, Richard=20 Sohn and Jerry (who has considerable expertise support) support my = own=20 theory - however there are differences of opinion on runner diameter. = Jerry's=20 advice supports my own theory - through considerable = evaluation.
 
In my opinion both theories are = correct, but for=20 different applications. Both PL and Jerry are on the cusp of = evaluating=20 their individual developments - we will see what we will = see.

I'd much rather have a P-Port and the simpler = porting.
I'm=20 P-P'ing the single with RX 8 rotor - for that very reason. George ( = down=20 under)

Hey = George,=20
 
All in = clean fun, how=20 is it that you figure it's "simpler" to make your own p-port, and plug = up the=20 factory ports, than it is to just use the factory ports that are = already=20 there?   9000 rpm not enough for you?   Is this = one of=20 those "things are different down there" situations we read about = in the=20 Australian tourism ads   :-) 
 
Cheers,
