Stop guessing your setup. Start dialing it. Racer.wiki is the only platform built from the ground up for real dirt oval racing — with live weather intelligence, banking measurement from your phone, and a crew chief who knows your chassis, the wind direction, and exactly where your track will be at feature time.
TIRE PRESSURE (PSI)
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 already in the system. GPS auto-detects your track on arrival. Banking, surface type, size — preloaded. No setup before setup.
GPS TRACK DETECTIONWalk 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 questions, setup direction between heats. He knows your chassis, your class rules, and tonight's conditions. Available 24/7 including via SMS.
AI-POWERED · SMS ACCESSLate Models to Street Stocks, Modifieds to Sprint Cars. Class-legal stagger ranges, weight percentages, tire pressures — all baked into the recommendation engine.
MULTI-CLASS COVERAGELive temp, humidity, dew point, baro, wind speed and direction — feeding a real-time DA calculator, corner-by-corner evaporation model, and jetting recommendation. Hunter reads the sky so you can focus on the car.
WEATHER · DA · WIND PHYSICSEvery setup card saved. Session results logged. Compare setups across events, recall what worked at this track last September, track lap time trends across a full season.
FULL SESSION LOGGINGEvery major dirt chassis with real suspension type, wheelbase, track width, 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 PREPARATIONStop typing into a chat box. The handling flowchart knows every class, every suspension type, every corner zone. Tap what the car is doing — get the one fix you need in under 30 seconds. No AI call. No wait. No vague answer.
Hunter 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.
Every tier is unlocked during our launch. Get in, use everything, and help us build the best racing platform ever made.
I've been running Late Models for 12 years. I paid a setup guy $300 a night for basically what this app does — and he wasn't always right. Hunter nailed my Eldora setup first try.
The banking walk feature alone is worth it. I walked Knoxville twice and got within 0.3° of what the track superintendent told me. Nobody else gives you that data.
My son is 19 and just started running Modifieds. This thing is like having a veteran crew chief teaching him every week. He actually understands his setup now.
The full Crew Chief experience — setup cards, Hunter, banking walk, session logging, jetting charts — completely free during our launch window. No card. No catch.
