Higher pressure leads to higher loads throughout the engine and particularly on the rings. For a 3.6L engine to produce the same amount of power (at the same rpm) as a 6.2L engine, the average cylinder pressure needs to be doubled. I want the engine that is only working half as hard.  |
Not sure where you are getting those numbers, can you provide some more info like a citation?
