Compare tire sizes and calculate overall diameter, speedometer error, and clearance. See how plus-size or downsizing affects gearing and fitment.
Calculate engine horsepower from torque and RPM or estimate from quarter-mile time and weight. Convert between HP, kW, and brake horsepower units.
Calculate fuel injector size from target horsepower, BSFC, and duty cycle. Size injectors for naturally aspirated, turbo, and supercharged builds.
Base estimate uses wheel horsepower per pound of vehicle weight. A ratio of 0.10 WHP/lb typically yields 4–5 second 0-60 times with good traction.
Power-to-weight = WHP / Curb weight (lbs)Convert crank HP to wheel HP before calculating. FWD loses ~12%, RWD ~15%, AWD ~18–22%. Turbo cars may have higher losses at peak boost.
WHP = Crank HP × (1 − Drivetrain loss %)Real-world 0-60 includes launch traction limits. The model applies a correction for tire grip, gearing, and aerodynamic drag using empirically fitted constants.
0-60 ≈ K × (Weight / WHP)^0.33Updated: July 2026
Power-to-weight 0.094 WHP/lb. Estimated 0-60: 4.8 seconds with good tires and launch control. Actual varies ±0.3 sec with driver and surface.
Power-to-weight 0.054 WHP/lb. Estimated 0-60: 8.5–9.5 seconds. FWD with CVT may be slower due to power delivery, not peak HP.
Crank 580 HP × 0.82 = 476 WHP, 4200 lbs. Estimated 0-60: 3.4 seconds. AWD launch advantage offsets higher weight.
0-60 happens at the wheels. Convert crank HP to WHP first (subtract 12–22% drivetrain loss). Using crank HP underestimates 0-60 time significantly.
Summer performance tires vs all-seasons can differ by 0.5+ seconds. Manufacturer claims use prepped surfaces and professional drivers. Real-world times are typically 0.2–0.5 sec slower.
Zero-to-sixty time depends on power-to-weight ratio, traction, gearing, and drivetrain type. This calculator estimates 0-60 mph acceleration from wheel horsepower, curb weight, and drivetrain loss for realistic performance comparison.
