Faster laps. Sponsors who renew.

Two tools from Dirt Slingin Tech: an app that shows where you lost time, and an audit that shows your sponsors what they got.

Dirt Slingin Tech app + RaceBox

See exactly where you gained or lost time.

Lap-by-lap comparison for dirt track racers. Pair a RaceBox and run your laps. The app times every lap and lines any two of them up against each other.

App screen comparing lap 3 and lap 4 at I-35 Speedway: both racing lines on a satellite map, a time-lost chart showing lap 4 finishing 0.08 seconds behind, and both speed traces.

  • Find where the time went

    Put any two laps on the same distance axis. The time-lost chart shows the spot where one lap got away from the other.

  • See the lap, not just the number

    Your line on a satellite map with speed traces and lap delta. RaceBox GPS feeds it and laps are detected for you.

  • Know which run was which

    Tag the driver, heat, feature, qualifying, practice or time trial, and the finish. Runs link to the race event, and the weather is saved with each session.

  • Keep your setups and race history

    Setup sheets with photos for modified, stock car, sport compact, late model, sprint car, micro sprint, go kart and legend, plus a race log.

  • Share it

    Send a run to your crew or export it.

How the audit works

Sponsors don’t renew handshakes. They renew data.

Your car was on the broadcast. Pit Sponsor counts how long each sponsor was on screen and puts a dollar figure on it, so the renewal talk starts with numbers.

  1. Send the replay link

    Give us the URL of the race replay and a list of the sponsors on the car.

  2. The engine scans every frame

    It finds your car and logs when each sponsor logo shows up, for how long, and how big.

  3. You get a PDF report

    A valuation report you can email or print and hand straight to your sponsors.
