A good 1D simulation like EngMod4T will show you that plus so much more. Buying Ricardo WAVE or GT-POWER might be slightly more accurate(you can plug in different burn models more easily) but unless an engine OEM are simply too expensive.

A curious person can learn more about ICEs in a few months with 1D software than a lifetime of learning via other means. It just requires careful measurements that most enthusiasts don't seem willing to collect.
