What is the absolute lowest seat pressure you'd need to seal a valve while the engine is running without having to follow the cam profile, so I'm talking absolute minimum. Valve float is not an issue to be discussed, period. But, still assuming the engine is running normally in it's normal operating RPM ranges. This goes for any race engine, from Clones to UAS.
Does RPM effect the pressure needed? Remember, not following cam profile, so valve float doesn't matter.
Does compression help seal the valves, or will it counteract and potentially lift the valves open due to harmonics if the valve doesn't have enough seat pressure?
Does Valve diameter change the pressure needed? More, or less depending on the size?
I'm sure I'll add more questions before I'm done, discuss!
