Judging the engine performace by the number of ports is a sillyness. A good 3 port engine can spank a 5 ports engine.
3 and 5 ports .12 engines are quite similar, probably the 5 ports are a little more efficient with the fuel and have a little better low-end, but main power can be the same or almost the same.
V12 engines should be real good, as my previous RB engines got an excess of low-end and missed some high-rpm power V12 will rock as the same model from Nova.
