Phil, on the other question that you asked "how long have you got" (if the fueling is lean on boost).......Ahmed told me that the first 8 - 12 seconds the engine cylinder/piston gets very hot - but can survive with just mild det marks if you realise and lift at this stage..........HOWEVER if you dont realise or lift then the next 8 -12 seconds will hole a piston - i.e. the temp in the cylinder will rise sharply enough to melt the piston

Been there BTW
