@Intruder, technically it's still an "thrust limit exceedance", not an overboost. Tdracer's argument that it "might" exceed limit in the compressor is something that we can't know. Probably it is wrong too, I read somewhere that the CFM56 was run at 140+% during testing. Probably there is a much wider margin for the compressor than what we are able to exceed with the engine on the wing.
