The Wallace 1/4 Mile Calculator is a crucial tool for motorsport enthusiasts, allowing them to estimate a vehicle's performance in a quarter-mile drag race. This tool calculates the elapsed time and the speed a vehicle might achieve during this specific race format.
Formula of Wallace 1/4 Mile Calculator
ET (Elapsed Time) Formula:
ET = (Weight / HP) ^ 0.3333 * 5.825
Where:
- Weight: The weight of the vehicle in pounds.
- HP: The horsepower of the vehicle.
MPH (Miles Per Hour) Formula:
MPH = 234 / (ET ^ 0.5)
Where:
- ET: The elapsed time in seconds.

Example of Wallace 1/4 Mile Calculator
Let's consider a vehicle weighing 3000 pounds with an estimated horsepower of 350. Plugging these values into the formula, we can calculate its expected elapsed time and speed in a quarter-mile drag race.
Elapsed Time (ET) = (3000 / 350) ^ 0.3333 * 5.825 ≈ 11.63 seconds
Miles Per Hour (MPH) = 234 / (11.63 ^ 0.5) ≈ 119.94 MPH
