Casey and Chuck lose the hood on their car. In the next shot, from inside the car looking out the windshield, the hood is still visible.

When the officer gives Chuck and Casey a ticket for trespassing on the drag strip, the landscape is flat. In the next shot, mountains can be seen in the background.
About 11:30 minutes into the film Chuck (Doug McClure) calculates the quarter mile time for the jet car. He states that the car would do 8.7 seconds in the quarter mile allowing for a one second throttle lag. With the figures provided, weight, thrust, lag and distance the time should be 7.69 seconds.
The one second lag Chuck (Doug McClure) figured into the quarter mile time is not completely correct, in drag racing the timing clock does not start until the car moves, not when the light turns green.
Peter Mann's character Stan is billed as "Stanford Rogers" but the name on the top of his race car says "Stanley Rogers."
