No it is not a quote! It took me from about 6:30 am tilll about 8:00 am to get it the way I wanted and then I had an edit after that

Its hard to make it brief and keep on the plot. When there are so many variables, its ard to keep it from being a piece of techno_ speak that is not easily understandable. Its a great subject and I am always looking for ways to improve efficiency and performance.

I was going to put some info on ceramic coating of chambers and pistons in there as well as this has an effect on the compression ratio you can run. Ceramic coating reduces heat soak into the chamber and piston. This reduces potential for detonation at high engine speeds. Maybe that will come into another thread.

At least on this site, people are more interested in technical stuff and how to do things. Not the grand standing (mines better or bigger than yours) you get on other sites

Any one doing engineering, if you get to do thermodynamics: do it! This is one of the most useful "real world" sciences there is in my opinion.
