There's a guy who autocrosses in the Los Angeles region, he's got a very fast Mitsubishi Evo. From what I hear, he lost an engine due to a pump problem which somehow hydrolocked the engine. I'll try to get more info from him next time I see him, I'm not sure if he still uses W.I. anymore or not.
He's got a very trick anti-lag misfiring system now...
