Actually the octane # required is determined by, at what point the mixture will ignite based on compression and spark advance. Running 100 unleaded in a stock engine will not hurt anything and once ignited the flame front moves much faster across the combustion chamber which produces a bigger bang. So you won't loose performance, but rather gain. This information comes from the lonely Unical information man in Santa Barbara.
