    I thought you guys had drivetrain issues? Or was that before dynamic events started?

    Either way unlucky. BOL next year

    Both engines had connecting rod bearing failures.
    The first engine started to make a ticking sound a day before comp. It became so loud that we failed the noise test thursday night, so we swapped engines friday. The new one worked until our second skid pad run when we started hearing loud ticking again, then the engine just wouldn't turn over.
    Our engine guy is doing a full autopsy on the engines this week. We're not sure if this was just bad bearings, or a problem caused by something we did to the car.

    For sure man, that is true. At least RR got to race in all events. That sucked for your engine, especially when I came over and saw all those chunks of metal =(. I hope you can figure out what caused it and fix it for next year!

    Con rod failure and loud ticking eh? At the risk of causing this thread to stray, I would recommend checking your ignition timing. It may not be common to get engine knock on this size of engine but with the right (read:wrong) amount of spark advance you can certainly achieve early detonation.
