All of these comments about blow through would be perfectly valid if we were talking about a system that does anything to the exhaust cam.

Until the variable phasing on the exhaust side is tunable, I don't see how it's relevant.

I don't see how holding the intake closed until the exhaust has closed would net you any real benefit since you'd be waiting until the piston was already on it's way back down before you open the valve. Surely any small gain you get from preventing blowthrough would be offset simply by there being far less time for gasses to enter the cylinder?

I mean, testing and time will tell, of course. Maybe they can work some magic?
