Here's a picture of the chart that records the cryo progress. I started it at 9:40 am as referenced from the 12:00 position of the chart[not 12:00 on the chart itself]. It started going down in temp 1° per minute over a 6 hour period[as referenced by the nice, gradual arc from 9:40 am - 3:40 pm] until it reaches -320°F. You can see that at about 4:20 pm the sensor probe plug lost connection and the recorder ran up off the chart. At 5:35 pm I noticed it and re-established connection, where it went back down to -320 where it should be. It's not the temp that went up and down. It stayed at -320°F for roughly 25.5 hours, then, at 5:30 pm, I drained the liquid nitrogen out and started bringing the temp back up at a rate of 1° per minute. At 11:30 pm, it was done.

The temp pics are from the next morning when I came in and pulled the stuff out. The crank was still 48.4°, and the oil pump was 54.9°. Don't know why I documented this, just did for sh*ts and grins I guess.
