Density altitude context at Hidden Valley Dragway
Hidden Valley Dragway sits at 39 ft. Density altitude — the altitude your engine "feels" — climbs from that baseline whenever the air gets hotter, more humid, or the barometer drops. Higher DA = thinner air = less oxygen per cubic inch = slower elapsed times.
Across the season at this strip, the difference between a cool, dry morning and a hot, sticky afternoon can be 2,000+ feet of DA — enough to swing a naturally-aspirated index car a tenth or more. A logbook tuned to live DA is the only honest way to compare passes day-to-day at Hidden Valley Dragway.
