This shows the various tuning RPM's Mazda achieved
with the three stage tuning on the RX8 engine. Each hump
in the torque curve represents a tuned RPM.
There appears to be at least two dynamic chambers in series.
Perhaps they are not dynamic chamber at all but merely
a series of valves that turn different runners on and off at
different RPMs. So far I have been unable to find a technical
description of the this system.
