This magnification of the dyno chart shows the difference between dynoing a ZX-9 with ambient pressure (lower line) and then stuffing 30 millibars of wind into the intake system-a gain of eight horsepower (from 123 to 131 at the peak). The manometer shows that the ZX-9 reaches 30 millibars of airbox pressure at 150 mph.
