Jumpy, blurry, dull in contrast and images Jalopies Race Hot rods get really hot on a dirt track and some of the ensuing crashes are really spectacular. The lowly hot-rod comes into its own. The much-misunderstood jalopy proves its worth during speed trials. Watching these cars racing around the track I would venture to guess on MPH to be maybe 75 - 90 (if that) As you watch these cars go around the track, you can see how unstable they are because of being top heavy. One car as its in a turn looses it and goes over landing on its side. The track is not even banked good. This is so prehistoric for car racing it must of been fun to drive those cars at the speeds they were averaging.
