great way to clean the chambers, yes.  But isn't the water volume
highest when vacuum is highest?  IE, when you need it least?  At WOT and
working hard, there is the least vacuum, right?

You can use a one way valve, but see above comment again.

With a turbo, of course, you could *pressurize* the water bottle, via an
adjustable restrictor valve, with a little "intake" air, and then the
higher the boost, the more water flows...?
