Does the computer just extrapolate the curve set at
say 3k-4.5k rpm?  If the other input parameters are
unchanged (WOT switch position, plate position,
manifold pressure) and the rpms continue to climb
progressively...Doah-just realized, that works fine if
injection is controlled by a computer.  BTW, if the
plate is at full deflection at 4.5k rpm, does
increased air velocity provide the additional air
required for the climb to redline?
