Interesting, operating principal. Seems like there would be a centrifugal stress issue with these.
For the sake of staying on track, I haven't picked though this entire thread but, we do know that open loop engages at X throttle position on MOST management systems, regardless of manifold pressure. With that, it is possible to achieve a higher MAP at <X throttle position. Due to the choked gas flow (among other working factors); the mass air flow of the intake manifold is higher with the slightly pressurized environment pre-throttle plate at <X tps in turn producing more hp in closed loop than the manufacturer intended for it to.
Obviously, this would eventually get dangerous or inefficient if the engine were to see these higher pre throttle plate pressures as it would be too lean to produce power efficiently and safely.
