Pit Stop Delta Calculator

Summary

Enter measured in-lap and out-lap times plus a representative green-flag lap to calculate the two-lap pit stop delta.

How it works

1. Enter your green-flag (normal race pace) lap time.
2. Enter the measured in-lap time for the lap where the driver enters the pits.
3. Enter the measured out-lap time for the lap where the driver exits the pits.
4. The calculator compares the complete two-lap pit sequence with two green-flag laps.

Use cases

• Compare pit crew performance between different stops.
• Decide whether a splash-and-dash is worth the time loss late in a race.
• Estimate the undercut or overcut gap needed to jump a rival on strategy.
• Analyze sim racing or esports pit stop data for setup improvements.
• Teach kart racing or club racing strategy basics.
• Benchmark real-world pit crew times against professional series averages.
