I'm not worried cause a block that resistant could only be used in something like a semi-rig on up--overly expensive and heavy. Somewhere on u-tube I thought I saw ballistics tests where they were shooting into simulated engine blocks made of jelloI would advise you to save your time, money and energy because I am in the process of developing a new generation of engine blocks that can defeat even 40mm anti-aircraft rounds.
Maybe these experts never served to defend this nation
All this talk about engine blocks brought to mind the fact that engine blocks are, or at least were, made from cast iron. Having said that, way back in the 70s my friends and I were out shooting in the Everglades and stumbled upon an abandoned (probably stolen) 1961 Ford with a V-8 engine still in it.
One shot from my friend's Mauser pistol put a hole in the side of the engine block. Obviously, this was below the cylinder heads, and I doubt it did any damage at all to the internals, but it was surprising to us all. It was then that I realized that cast iron engines weren't that strong , at least at the lower end.
Based on that experience, I don't see where it's that big of a deal to put a hole in an engine, unless they're made a lot tougher now.
Cracking a cast iron exterior of an engine block and putting a hole in that exterior is alot different than penetrating the engine block and punching completely through the other side.
very good points--I guess what this reinforces is that placement of the shot is more important than anything when it comes to stopping an engine. It also points out the importance of realistic training in order to be prepared for the day when you really need it. I wonder how many shooters really spend enough time in the junkyards these days.Shooting through an engine block is a pretty wide open statement anymore. Is it a front wheel drive 4 cylinder or V6 or a V6, V8 rear wheel drive. To many variables to predict, con rods and crankshafts would be pretty tough. A side shot on an aluminum 4 cyl not so much.
Stagpanther, a hole with some metal debris through an intercooler could have a pretty detrimental effect on a supercharged or turbocharged engine. It would more than likely cause the rotors in the supercharger to seize and stop airflow to the engine completely.
A lucky shot in the ECU would probably be the most effective location to stop the vehicle.
I wouldn't bet against a 308 not doing some pretty significant damage though.
