First, pregnant women and ALL children can stay the hell away from the race
track when I am racing if they don't want to risk damage, and second, this
thread has chugged on too long while for the most part missing the point.
MGs don't run on because of a requirement for high octane gas, they run on
because they have a lousy head design, an even poorer standard of finish on
the head itself (a few minutes at the factory with a high speed grinder would
have relieved 90% of the hot spot problems). With a clean (non-carboned) head
you can run 10:1 on pump unleaded without problem. Anyone with lower
compression than this that is looking to avgas or any other high octane fuel
is just fooling themselves - the high test stuff burns slower and gives LESS
power guys.
