Rarlyl8,
You have alot of good insight on this forum. I agree with your opinions on this and alot of other postings.
The reason for twin pluggung is clear, it is a benefit, but should be looked at from a safety standpoint first. It gives the ability ot run higher boost and timing by increasing the safety margin to detonation, but here the tuner is creeping up again to the danger zone when attempting this.
Porsche like any other OEM during the 80's had lots of trouble and this explains the ridiculously long time running CIS on the turbo models long after the switch was made on the 3.2 liter cars to Motronic.
The expense is prohibitive to dual plug when you look at the machining involved in not just the heads, but the valve covers, engine tin, changing over the ignition system. You could find easier uses for this dough to gain power from the 930 by first improving the exhaust breathing and other things on the car that were compromised in the sake of emissions.
