AI CREW CHIEF · 725 TRACKS · 6 COUNTRIES · WORKS OFFLINE
Great setup knowledge used to live in the heads of a few expensive engineers, buried in old notebooks, or scattered across unreliable forum threads. If you didn't know the right person, you were guessing.
Racer.wiki changes that. We encoded decades of real dirt track engineering into an AI that knows your class, your chassis geometry, your track's exact banking angle — and outputs a setup card you can actually use at tech.
Every major dirt oval across the US, Canada, Australia, UK, New Zealand, and South Africa. GPS auto-detects your track on arrival. Banking, surface, size — preloaded. Show up and race.
GPS DETECT · 6 COUNTRIESWalk the turns with your phone and our banking walk tool measures actual banking angles to the tenth of a degree using your accelerometer. Community-validated and always improving.
ACCELEROMETER MEASUREMENTAsk Hunter anything — handling problems, jetting, setup direction between heats. He knows your chassis, your class rules, tonight's conditions, and your track's banking. Diagnostic trees work offline with no signal. Your crew chief is always in your pocket.
AI-POWERED · WORKS OFFLINESprint Cars to Late Models, Modifieds to Micro Sprints, Karts to Street Stocks — plus international classes from Australia, UK, New Zealand, and flat track moto. Class-legal stagger, weight %, tire pressures — all baked into the recommendation engine.
9 DIVISIONS · 50 ENGINESLive weather feeds a real-time DA calculator, evaporation model, and jetting recommendation. No signal? Type in the readings from the tower weather station — the DA calculator runs offline, no internet needed. Hunter reads the sky so you can focus on the car.
WEATHER · DA · OFFLINE CALCULATORSetup cards saved to your phone. Race night format builder tracks your car through hot laps, heats, and the feature. Post-race remeasure shows what changed. Your setup history travels with you — even offline.
OFFLINE STORAGE · RACE FORMAT BUILDERStallard, XXX, Hyper, Eagle, Rocket, Longhorn, GRT, Spike, and 175 more. Real suspension geometry, wheelbase, roll center tendency, and setup modifiers that adjust AI output for your specific car — not a generic template.
CHASSIS-SPECIFIC AIPhoto your turns, document how the track evolves across the night. AI analysis tells you what the surface is doing and how it should affect tire pressure calls between heats.
AI SURFACE ANALYSISPenetrometer readings, moisture %, IR surface temp, ribbon tests — log pre-race dirt data and Hunter factors track conditions directly into your setup card before you turn a wheel.
PRE-RACE PREPARATIONHunter is the AI crew chief built into Racer.wiki. He's not a chatbot that reads Wikipedia. He knows your chassis geometry, your class rules, your track's banking, and tonight's density altitude.
Ask why your car is tight off the corner. Ask if you should go up or down on the J-bar for the feature. Ask what jetting the track conditions call for. He answers like an engineer, not a search engine.
Banking angle is the single most important variable in a dirt oval setup calculation. Until now, getting an accurate number meant hiring a survey crew or knowing someone who already had it.
Racer.wiki's Banking Walk uses your phone's accelerometer to measure banking as you walk each turn. Multiple readings are averaged, cross-validated, and assigned a confidence score — then fed directly into your setup engine.
Temp from Weather.com. DA from AirDensityOnline. Uncorrected barometric pressure from an airport ASOS. Wind forecast from Windy. All before they can even start thinking about the setup. Racer.wiki is one screen.
No more tab-switching between sites. No more forgetting to check the ASOS before you jet. No more wondering if your density altitude is calculated from the wrong barometric pressure.
Calculated from uncorrected station pressure — not the sea-level-corrected number Weather.com shows, which is useless for jetting. Same math your Kestrel uses.
The full AirDensityOnline suite — grains of water per lb of air, relative air density %, vapor pressure — all calculated from live data and displayed in one shot.
Direction relative to your track's orientation. Which corners get tailwind. Estimated downforce loss in pounds on winged cars. A flag when the gust spread is so wide that setup can't compensate.
Real evaporation rate math using temp, humidity, dew point spread, and wind — projected by race stage so you're setting up for lap 20, not hot laps.
Main jet size, needle clip position, pop-off PSI — calculated from tonight's actual DA for your specific engine. No chart. No math. Just the numbers.
The full Crew Chief experience — setup cards, Hunter, banking walk, session logging, jetting charts — available now with a 14-day free trial. Plans start at $8/mo.

An AI crew chief is an artificial intelligence system that provides real-time racing setup advice, handling diagnosis, and strategy recommendations — the same role a human crew chief fills on race night. Racer.wiki's AI crew chief, Hunter, is trained specifically on dirt oval racing physics, chassis geometry, and weather science to give you actionable setup changes, not generic advice.
Real racing only. Racer.wiki is built from the ground up for real-world dirt oval racing — sprint cars, late models, modifieds, street stocks, micro sprints, midgets, and more. We use real weather data, real track banking angles measured by phone accelerometer, and real chassis geometry from 165 chassis profiles. This is not a sim racing tool.
Select your track, class, and chassis. The AI crew chief pulls live weather data (temperature, humidity, density altitude, barometric pressure, wind), your track's banking angles, and your chassis's specific geometry profile. It then generates a complete setup card — tire pressures, stagger, weight percentages, spring rates, panhard bar height, J-bar angle, and more — tuned to tonight's exact conditions.
165 classes across 9 divisions — Sprint Cars, Late Models, Modifieds, Micro Sprints, Karts, Midgets, Street Stocks, Sport Mods, Micro Sprints, Midgets, Mini Sprints, Factory Stocks, Hobby Stocks, LO206 Karts, Quarter Midgets, Jr. Sprints, and many more. Each class has its own rule set, legal ranges, and setup parameters built into the AI engine.
Yes — during our launch period, every feature is completely free with no credit card required. This includes the AI crew chief, setup card generator, banking walk tool, live weather engine, handling diagnosis, dirt test mode, and session logging. We want racers using it and giving feedback before we turn on paid tiers.
Yes. Hunter, the AI crew chief, is available via SMS. Text your handling problems between heats, ask about jetting changes, or get a quick setup adjustment — right from your phone in the pits. No app required for SMS access. Hunter knows your car, your track, and tonight's conditions.
Drag Garage is the bracket racing tool at racer.wiki — log dial-in, reaction time, 60-foot, staging depth, and tire pressures per pass. Build your dial from a rolling average instead of guessing from memory. Free to use. Pair it with Hunter's bracket column at /column.
Not yet — we are building Road Racing Garage now (corner weight, brake bias, stint tire deg, quali vs race line). Leave your email on the homepage garages section and we will notify you when it opens. Dirt Garage and Drag Garage are live today.
Density altitude is the altitude your engine thinks it's running at based on current temperature, humidity, and barometric pressure. Higher DA means thinner air and less engine power — which affects jetting, tire pressure, and setup. Most weather apps show sea-level-corrected barometric pressure, which gives you the wrong DA. Racer.wiki uses uncorrected station pressure from the nearest ASOS station for an accurate calculation — the same math your Kestrel weather meter uses.
