No sir I did not.Zell, you obviously didnt read any of my posts on the cap.
I gotta be honest , Im not very good with these terms. All I know is that whenever our system reaches an internal pressure higher then 2.0 bar / 29psi (200kpa), the caps inner vale would open and the pressure would be released and maintained at 29psi (200kpa)It would have to be 15psi relative to the atmosphere wouldn't it? Meaning that the absolute pressure would be about 30?
I'm not entirely sure if the stated pressures are relative to the atmosphere or if they're absolute. Relative would make more sense to me. A cap that regulated to 1-bar absolutely would effectively be the same as not having a cap at allI gotta be honest , Im not very good with these terms.

The other (E30) cap has a rating of 1.4 bar / 20psi (140kpa) and therefore it would maintain the inner pressure of the system at that level.
You are correct. Gauge pressure, not absolute.I'm not entirely sure if the stated pressures are relative to the atmosphere or if they're absolute. Relative would make more sense to me. A cap that regulated to 1-bar absolutely would effectively be the same as not having a cap at all
In that case Zell's table is wrong - the right column should be shifted down by 1 bar. In which case even the RR cap would allow enough pressure to build to not have to worry about the coolant boiling at normal temperaturesYou are correct. Gauge pressure, not absolute.
Playing the "I'm really more stupid than you even think card" will not cut it for much. I know you know stuff. And "anyone who pursues learning lots about complex science is an idiot" indicates your respect for education. Your advice therefore is stay ignorant?Heaven forbid us dumb high school grads try something the highly paid engineers have all figured out. I haven't found much that can not be improved Stinger, are you an automotive engineer? I could care less for most of them, there's never enough R&D.
