The Dirt Track at LVMS

Tonight's setup at The Dirt Track at LVMS

The Dirt Track at LVMS is a clay oval in Las Vegas, NV. On dirt, three numbers decide your night: density altitude (how much power the air gives you — shown live above), stagger and cross weight (how hard the car turns left), and where the track surface sits in its dry-down. Nail those for tonight's conditions and you are racing, not guessing.

Density altitude at The Dirt Track at LVMS

As temperature, humidity and barometric pressure shift across a race night near Las Vegas, the density altitude above moves with them — and your jetting and tire pressure should follow. Most weather apps show sea-level-corrected pressure, which gives the wrong DA; racer.wiki uses uncorrected station pressure for the real number. Read the full density altitude guide →
