Hey, Peter, I was with you until that last paragraph. All I can say to that one is - what??? Can you please re-explain that as if talking to a distracted-drowsy-ADD two year old. If you can swing that, I might catch some of what you're talking about. What is a Carnot Cycle engine?

Re: 12 cyl. Jag. Tuned and running it is one of the finest experiences you may ever have. Tremendous responsiveness and a vibration that feels like it is in tune with the cosmos. That peak is hard to acheive and much, much harder to maintain. Many have burned. I think that possibly some people have torched their V-12's when they discovered what a huge and terrible task lay ahead when all they had to do was remove the valve cover.
