I can only speculate what happened here as I didnt see it but I sure as hell heard it and felt it. We heard/felt a rather large boom at work today, somebody went to investigate and this is the cause. I suspect, as the person had just apparently spent $2k on engine mods, a dodgy fuel rail leaked some petrol onto the battery which caused a spark and the following explosion and fire. From the photo you can see some sort of engine with a turbo, it was a commodore so perhaps one fitted with a rb30det. I feel sorry for the owner, but at the same time its a commodore
