true, but in Honda’s application, they also alter there timing and don’t forget that both the intake and exhaust camshafts have 2 different profiles, it may not be adiabatic efficient, but your getting low amounts of boost and keeping the intake valves closed more also during low RPM and not wot thus improving fuel economy and smoothing out the transfer from in Hg to psi, because in a perfect world (or race application) you want to be in boost asap, but in a daily thats not necessary and or practical…
