I don't have any cool pics but I can make a list of stuff we've killed.
We seized our motor in practice two weeks before the second race due to incorrect bearing installation. Working on the car late at night may lead to some boo boos. We replaced the 1 sieved rod bearing, replaced the crank with one from a free motor I got and swapped the rod and piston. We saved the motor for like $50-60.
Our most common issue we have had has been clutches! Our first clutch died as the lining material left the disc in chunks. It was off our parts car and came as no surprise when it died. The second clutch on the other hand was unexpected and looked like cat hair in the pressure plate. It died after the transmission got screwed.
We bent the roll pins on our 4 speed causing us to lose 4th gear in race #2. In race #3 something happened to the 5 speed and it vibrates the car, don't know what happened yet just that the vibration is from the transmission.
Our battery hold down somehow grounded the battery. This smoked the positive battery cable and caused the battery to melt around the hold down. Miraculously, the battery and alternator lived through the whole thing.
We've had miscellaneous issues but nothing as cool as adding air cooling to a water cooled VW motor.
