I was looking for the differences between the old 6.1 hemi and the new 392. I'm surprised by the potential of the new hemi. I can't wait to see how much power it would put with some aftermarket mods. Though I have noticed that the old 6.1 has a 10:3:1 compression ratio whereas the new 6.4 has a 10:9:1 compression ratio. From my basic knowledge and internet research I concluded that as a rule of thumb a lower compression ratio engines are more boost friendly than higher compression ratio motors. For example a stock 6.1 would handle more boost just because its running a lower compression.
Maybe this analysis is very basic but is it true?
