Formula:

The 1/4 Mile ET (Elapsed Time) and Trap Speed are estimated using simplified formulas that consider your vehicle's Horsepower (HP) and Weight. While various factors influence actual track times, these formulas provide a good approximation:

ET ≈ C1 * (Weight / HP)1/3

Trap Speed ≈ C2 * (HP / Weight)1/3

  • ET: Estimated Elapsed Time in seconds
  • Trap Speed: Estimated speed at the 1/4 mile mark in MPH
  • Weight: Vehicle's curb weight in pounds (lbs)
  • HP: Engine's horsepower (brake horsepower)
  • C1: A constant (approximately 5.825) for ET calculation.
  • C2: A constant (approximately 234) for Trap Speed calculation.

Note: These formulas provide an estimation. Actual track results may vary significantly.
