- **Density Altitude & Car Performance | FastTrack** ([https://fasttrackapp.biz/guides/density-altitude-and-car-performance](https://fasttrackapp.biz/guides/density-altitude-and-car-performance)) — Density altitude combines air temperature, humidity, and barometric pressure into a single number that predicts how much power your engine will make on a given day. A naturally-aspirated car can lose 3-5% horsepower per 1,000 feet of density altitude — the same 0-60 run can be half a second slower on a hot, humid afternoon than a cool morning. *Last reviewed: 2026-08-07.*
- **FastTrack Timing Accuracy vs Dragy & RaceBox | FastTrack** ([https://fasttrackapp.biz/guides/fasttrack-timing-accuracy](https://fasttrackapp.biz/guides/fasttrack-timing-accuracy)) — FastTrack times 0-60, 0-100, and quarter-mile runs to within ±0.02 seconds on iPhone — inside the accuracy window of a $179 Dragy and within 0.01s of a $499 RaceBox Micro. Launch detection averages about 30 ms, roughly three times faster than a GPS-only device. *Last reviewed: 2026-05-12.*
- **Free Dragy Alternative for iPhone — FastTrack** ([https://fasttrackapp.biz/compare/dragy-alternative](https://fasttrackapp.biz/compare/dragy-alternative)) — FastTrack is the free iPhone alternative to a $179 Dragy GPS Performance Box. It measures 0-60, quarter-mile, rolling-start, and custom speed ranges with ±0.02 second accuracy and adds garage, leaderboards, marketplace, and social features Dragy doesn't offer.
- **Free GPS 0-60 Timer for iPhone — FastTrack** ([https://fasttrackapp.biz/timing](https://fasttrackapp.biz/timing)) — FastTrack times 0-60, 0-100, quarter-mile, and half-mile runs from a stock iPhone with no extra hardware. Accuracy is within ±0.02 seconds of dedicated devices like Dragy and RaceBox, and launches are auto-detected so you can keep both hands on the wheel.
- **Free RaceBox Alternative for iPhone — FastTrack** ([https://fasttrackapp.biz/compare/racebox-alternative](https://fasttrackapp.biz/compare/racebox-alternative)) — FastTrack is the free iPhone alternative to a $279+ RaceBox Mini. Timing accuracy is within ±0.02 seconds — comparable to RaceBox for 0-60 mph and within 0.04s on quarter-mile ET — and you get garage, leaderboards, marketplace, and social features RaceBox doesn't bundle.
- **How Accurate Are Phone GPS Timer Apps? | FastTrack** ([https://fasttrackapp.biz/guides/gps-timing-accuracy-explained](https://fasttrackapp.biz/guides/gps-timing-accuracy-explained)) — Phone GPS timer apps are accurate enough for serious enthusiasts when they fuse GPS with the internal accelerometer. FastTrack on iPhone hits ±0.02 seconds on 0-60 runs — matching dedicated $179-$499 GPS devices for most use cases, and only behind external-antenna hardware on the absolute tightest measurements. *Last reviewed: 2026-05-12.*
- **How to Improve Your 0-60 Time | FastTrack** ([https://fasttrackapp.biz/guides/how-to-improve-your-0-60-time](https://fasttrackapp.biz/guides/how-to-improve-your-0-60-time)) — The fastest ways to drop your 0-60 time are launch technique, weight reduction, and traction upgrades before bolt-on power mods. Most stock cars find 0.3-0.6s by nailing the launch alone. *Last reviewed: 2026-08-07.*
- **How to Make Your Car Faster - Complete Mod Guide | FastTrack** ([https://fasttrackapp.biz/guides/how-to-make-your-car-faster](https://fasttrackapp.biz/guides/how-to-make-your-car-faster)) — The fastest way to make your car faster is to start with the free stuff — weight reduction, tire pressures, alignment, and launch technique — then move to bolt-ons (intake, exhaust, tune) and finally power adders. A structured, measured approach finds 0.5-1.5 seconds of 0-60 improvement on most cars before you spend on forced induction. *Last reviewed: 2026-08-07.*
- **How to Measure Your Car's 0-60 Time Accurately | FastTrack** ([https://fasttrackapp.biz/guides/how-to-measure-0-60-time](https://fasttrackapp.biz/guides/how-to-measure-0-60-time)) — Accurate 0-60 timing on a smartphone needs GPS-plus-accelerometer sensor fusion, a flat run surface, and a launch-detect trigger that ignores brake-creep. FastTrack measures to within ±0.02 seconds on iPhone with no extra hardware. *Last reviewed: 2026-05-12.*
- **How to Sell Car Parts Online | FastTrack** ([https://fasttrackapp.biz/guides/sell-car-parts-online](https://fasttrackapp.biz/guides/sell-car-parts-online)) — The best place to sell car parts in 2026 depends on what you're selling: enthusiast-specific apps like FastTrack reach buyers who already own your car, eBay reaches the widest audience with seller protections, and Facebook Marketplace works for local heavy items. Good photos, fair pricing, and clear fitment notes matter more than the platform. *Last reviewed: 2026-05-12.*
- **iPhone GPS Timer Accuracy vs Dragy & RaceBox — FastTrack** ([https://fasttrackapp.biz/accuracy](https://fasttrackapp.biz/accuracy)) — FastTrack achieves 0-60 mph accuracy within ±0.02 seconds of a $179 Dragy and within 0.01s of a $499 RaceBox Micro by fusing the iPhone's GPS and motion sensors. Launch detection averages about 30 milliseconds — roughly three times faster than a GPS-only device.
- **Quarter Mile Calculator: Estimate Your ET | FastTrack** ([https://fasttrackapp.biz/guides/quarter-mile-calculator-et-estimator](https://fasttrackapp.biz/guides/quarter-mile-calculator-et-estimator)) — Quarter-mile ET can be estimated from horsepower and weight using the Geoffrey Fox formula: ET = 6.290 × (weight ÷ hp)^(1/3). The Huntington formula refines this for modern cars. Both get within 0.2 seconds of measured times on well-prepped traction, but real GPS data beats any formula. *Last reviewed: 2026-05-12.*
- **Quarter Mile Calculator: ET & Trap Speed | FastTrack** ([https://fasttrackapp.biz/tools/quarter-mile-calculator](https://fasttrackapp.biz/tools/quarter-mile-calculator)) — FastTrack's quarter mile calculator estimates your car's ET and trap speed from horsepower and weight using the proven Roger Huntington formula. Apply correction factors for real-world variance — track surface, weather, tire grip — to get a credible target before you stage at the line. *Last reviewed: 2026-05-13.*
- **Rolling Start Testing: 40-100, 60-130 & More | FastTrack** ([https://fasttrackapp.biz/guides/rolling-start-testing-guide](https://fasttrackapp.biz/guides/rolling-start-testing-guide)) — Rolling start tests (40-100, 60-130) measure pure powertrain output without launch traction variables. They're the standard for enthusiast comparisons because they're repeatable on public roads in seconds, and GPS-based timers like FastTrack can record them to ±0.02 seconds. *Last reviewed: 2026-05-12.*
- **Stage 1 vs Stage 2 Mods Explained | FastTrack** ([https://fasttrackapp.biz/guides/stage-1-stage-2-mods-explained](https://fasttrackapp.biz/guides/stage-1-stage-2-mods-explained)) — Stage 1 mods are bolt-on upgrades on a stock engine — tune, intake, exhaust — typically netting 10-30% more horsepower on turbo cars. Stage 2 adds supporting hardware (intercooler, downpipe, fueling) for 30-60% gains. Stage 3+ requires built internals and is no longer a bolt-on category. *Last reviewed: 2026-08-07.*
- **Track Day Timer Guide: Time Runs at the Strip | FastTrack** ([https://fasttrackapp.biz/guides/track-day-timer-guide](https://fasttrackapp.biz/guides/track-day-timer-guide)) — A GPS timer like FastTrack records every lap, sector, and roll-on without needing transponders or track-installed timing loops. Set it up before your first session, measure your baseline lap, and compare runs to spot where you're actually losing time — usually braking points and corner-exit throttle, not straight-line speed. *Last reviewed: 2026-05-12.*
- **What's a Good Quarter Mile Time? (Bracket Chart) | FastTrack** ([https://fasttrackapp.biz/guides/quarter-mile-time-explained](https://fasttrackapp.biz/guides/quarter-mile-time-explained)) — A good quarter-mile time depends on the car class: sub-10 seconds is supercar territory, 11-12s is modified-street, 13s is fast-stock, 14-15s is daily-driver V6, and 16s+ is economy. Use a GPS timer to measure yours accurately without a dragstrip. *Last reviewed: 2026-08-07.*
- **Why Grip Matters More Than Horsepower | FastTrack** ([https://fasttrackapp.biz/guides/traction-and-grip-guide](https://fasttrackapp.biz/guides/traction-and-grip-guide)) — Grip almost always matters more than horsepower for street acceleration: a 300 hp car on sticky tires will out-launch a 400 hp car spinning all four. Tire compound, weight transfer, and drivetrain layout (AWD launches fastest, FWD is traction-limited, RWD needs technique) determine how much power actually reaches the ground. *Last reviewed: 2026-08-07.*
