On the post with the diesel exploding, I saw a twin turbo Porsche self destruct like that at a stadium auto-cross back in 2001 or so. The owner's "mechanic" had forgot to hook up the sensor lines to both blow off valves (electronic boost control) and it blew two of the right hand heads clean off the engine, fractured the case so it looked like a dry river bed and blew the engine lid about 20 feet in the air after ripping the hinges off! Mark Kinnenger estimated probably about 10 bar of boost more or less! The owner/driver said it sure did accelerate well in 1st and 2nd.........
