Hi Johnny
I have a P160 MK2 that has been working also very well in my KingCat. Temps around 650 -660 at full power. I talked with Bob a while back and in his visit to Germany, JetCat found that a 12 stick injector aids in a much more stable / even combustion pattern. This apparantly allows for cooler / more stable operating temps as well. Although my engine is working perfectly I plan on the upgrade - if nothing else the combustion chamber will appreciate the difference. IMHO the P160 is about as maxed as it can get in thrust production. Any improvements that result in ccoler temps, more stable combustion ( even minute ) make the package better.
