Real numbers for real cars
InRace turns GPS telemetry into verified performance data: horsepower measurement, lap-time boards on real tracks and public car profiles.
How it works
Record
Do a full-throttle run on a track with any GPS logger — RaceBox, Dragy or RaceChrono.
Upload
Drop the log file into GPSDyno and enter your car's weight. No sensors, no dyno booking.
Get the numbers
SAE-normalized engine power, a composite power curve, acceleration intervals and lap analysis.
Fresh from the track
GPSDyno
Physics-based horsepower measurement from GPS telemetry, calibrated per track surface. Repeatable, comparable, shareable with one link.
Measure power →Track leaderboards
Lap-time boards for real tracks and their configurations. Every run you upload lands on the board of its track — personal records, classes by weight-to-power ratio, seasons.
Browse tracks →Garage & blogs
A public profile for your car with verified dyno history, photos and onboard videos. Document the build in your blog.
