No chance at all of overspeecing a Vortech without aloso overspeeding the
engine--making the Vortech the least of your worries after the fact. It
will in fact make the Vortech(ed) engine run at a far better BSFC at part
throttle, due to far less parasitic drag. Also keeps you much further away
from the surge line for the compressor.
