Oh, and of course those percents are only the hp available in relation to the 100% power at those different manifold pressure/rpm settings, as opposed to a just a throttle setting, since you need to change the pitch to get the rpms to acheive that, but thanks for the chart...

Manifold pressure is an indicator of the supercharger, and when to change gears. The higher the altitude the less the pressure you will get. At a certain point you will shift blower gears.
