Balanced clay substrate — typical Midwest dirt; groove moves out as rubber builds.
Horse Power Park is a kart track in Morganton, NC. Three things decide your night: density altitude (how much the air feeds the motor — shown live above), seat and lead placement, and tire pressure as the surface comes in.
As temperature, humidity and barometric pressure shift across a race night near Morganton, the density altitude above moves with them — and your tune 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 →
