Anyone have any ideas on this?
I have seen several explosions that would disagree with your idea. Normally the point of ignition suffers much less damage compared to what the wave front hits at max speed. I remember reading somewhere that detonation normally has an ignition point that is somewhere in the volume of the cylinder (ie away from the walls or the piston of the spark plug). This would explain why holes are punched into the piston and somtimes break the valves as these are the weakest points. I don't know if there is an example of detonation damaged engine the suffered both a hole in the piston and damaged valves?
Power, whether measured as HP, PS, or KW is what accelerates cars and gets it up to top speed. Power also determines how far you take a wall when you hit it
Engine torque is an illusion.
