Racing the air at Summit Motorsports Park
The physical elevation here is 853 feet, but your engine doesn't read a survey marker — it reads density. On a hot, humid afternoon the density altitude at this track can run thousands of feet above the physical elevation, and your car slows exactly as if you'd towed it up a mountain. On a cool, dry morning it can run below it.
Three moves once you know today's number: check what the air does to your ET with the weather-corrected ET calculator, size your jet change with the jetting calculator, and if you bracket race, expect your dial to move with the density trend through the day — the pattern is in the bracket racing math guide.
