Drag racing data tools for serious racers
Drag Racing Logbook and ET Predictor
Drag Race Logbook Pro turns paper time slips and run history into practical race-day decisions. Photograph a time slip or logbook page, review the extracted data, and keep every pass organized by car, track, weather and race distance.
How does Drag Race Logbook Pro help racers?
Drag Race Logbook Pro brings time-slip capture, digital run logging, weather context, density-altitude calculations and ET prediction into one workflow. It is designed for bracket, sportsman, class and junior dragster racers who want a consistent record without retyping every number after a pass.
- Track reaction time, 60-foot, 330-foot, 660-foot, ET, MPH, dial-in and notes.
- Organize multiple cars, tracks, race distances and maintenance records.
- Export your run history for analysis or backup whenever you need it.
How does the time-slip scanner work?
Use a phone camera to photograph a printed time slip or a page from a paper logbook. The scanner identifies common drag-racing fields, presents the extracted values for review, and keeps each field editable before it becomes part of your saved history. That review step matters because racers remain the final authority on their data.
How does the ET predictor use weather and density altitude?
The predictor compares a specific car's historical runs with the conditions recorded for each pass. Temperature, humidity, pressure, elevation and density altitude help explain why the same car can produce different elapsed times on different rounds. Use the result as a data-backed baseline, then compare it with the pass you actually made.
NOAA explains the role of atmospheric conditions in weather observations and forecasting. The NOAA reference provides external atmospheric context for this product's educational content.

What can racers track between rounds?
Cars and tracks
Keep separate history for every car and browse the public drag-strip directory for track location, elevation, length and surface details.
Weather and performance
Record atmospheric conditions alongside each run, compare passes across different air, and review trends instead of relying on memory.
Practice and race preparation
Use the Practice Tree to rehearse reaction-time routines and return to the dashboard with the information needed for the next round.
Frequently asked questions about drag racing logbooks
Can I import old paper logbooks?
Yes. Photograph logbook pages and review the extracted runs before saving them. Free accounts include a small sample of imports so racers can evaluate the workflow.
Does it support 1/8-mile and 1/4-mile racing?
Yes. Runs can include the distance-specific split and elapsed-time fields used for eighth-mile and quarter-mile racing.
Can I edit scanner results?
Yes. Every extracted field is editable before the run is saved, so the racer can correct a number or add context from the time slip.
Who builds Drag Race Logbook Pro?
Drag Race Logbook Pro is built by Philip Irby, founder and lead engineer with 15+ years in software engineering, sports-performance analytics and computer vision, and an active bracket racer. Learn more on the About page.
