I talk about compression ratio. What is is, and what it means. I also talk about how you figure out the compression ratio of an engine.
I also go over what expansion ratio is, and what it means for power production.
I also talk about how your camshaft affects compression ratio, that’s right what camshaft you are running will make a difference in the actual compression your engine has.
Here is the link I mentioned in my podcast about the relationship of your cam and the compression ratio of your engine.
