[QUOTE="Shaun@AED, post: 13802544, member: 32381"] Boost is simply back pressure. Mass of airflow thru the engine is what produces power and therefore increases cylinder pressure. The valve event vs boost reference was simply an example. You can log lb/min of airflow and adjust cam timing for more/less airflow at a given RPM. Keep in mind the other effects cam timing will produce, like reversion, EGR, etc. This can lead to higher cylinder temps if exhaust gasses are re-entering the combustion chamber due to reversion along with other effects that are not desirable.
