rather an unusual statement..
if that is the case ............'more efficient than anything you might
ad'...
then I would say ..
since a conventional radiator cap ...like the one the diesel vanagon uses ..
where the entire rubber sealing 'plate' lifts up to relieve pressure ..
surely that style would allow more volume to pass than a waterboxer pressure
cap releasing through that small hose nipple connection.
and ....needing a lot of volume to be released quickly..
not an issue at all really in automotive cooling systems.
I'd even say the reverse,
since you don't want it releasing pressure really ( other than to keep
pressure reduced on hoses and head gaskets ) .....you really only want it to
be 'adequate.'
I like the idea of the on-board pressure gauge..
then you REALLY know if pressure is right, and not excessive etc.
and it would definitely give early warning ..
or could give early warning of impending 'bad stuff.'
You can have for example........ok coolant temp under huge load ..
and pressure is getting very high ( say pressure cap stuck closed ) and you
would not know it from just looking at the coolant temp gauge, but combined
with a Cooling System pressure gauge ..
then you'd have very useful information,
and could take some action before it's too late.
as stated elsewhere ..I believe in Water Wetter now ..
quite a bit. It's on the diesel list that I posted..
I just had a 1,340 mile trip in my 85 Adventuewagon with 2.1 waterboxer
engine.
the temp needle acted like it was glued in place, it was so consistent.
and it was in hot temps too, Baby. I believe in that stuff.
