Proper AFR's are just the baseline at that point. If the octane of the fuel isn't high enough bad things will happen fast. Engines need special build parameters to support high boost levels and high octane fuel which can burn hotter than gasoline depending on the mix. Typical OEM head studs and hardware are not used. I have seen pictures of heads welded on race engines, now THAT is hard core!
