(HPc) and output for current weather conditions as well as MSA
conditions.
For this example, the track’s elevation is 3,963 feet above sea-
level. Recall that our race car weighs in at about 3,840 pounds,
including the driver, and produces about 411 HP in ideal or MSA
conditions. The current local measured weather conditions are 73°
F, absolute pressure of 25.88 in Hg, and 14% relative humidity.
