# How To 1 8th mile horsepower calculator: 8 Strategies That Work

Measure the torque in pound-feet (lb-ft). Record the engine's rotational speed in revolutions per minute (RPM). Use the formula: Horsepower (HP) = (Torque × RPM) / 5252. Multiply the torque by the RPM. Divide that number by 5252. This formula gives you the horsepower, reflecting the engine's power output.October 9, 2023 by GEGCalculators. For 1/8-mile drag racing, a common gear ratio is around 4.56:1. This ratio provides strong acceleration off the line, which is crucial for the shorter race distance. However, the ideal gear ratio can vary based on your vehicle’s power and tire size.Engine Calculators. Calculate engine’s dynamic compression ratio and engine volume. Calculate change in fuel injector flow from change in fuel pressure. Calculate size of carburettor needed in CFM. Convert airflow to a different depression. Estimate horsepower from intake airflow. Estimate the horsepower gain from adding blower pressure.The formulas are: Estimated RWHP for 1/4 mile = (MPH/234)^3*Weight. Estimated RWHP for 1/8 mile = (MPH*1.27/234)^3*Weight. And it is estimated that RWHP is between 80% to 85% of flywheel horsepower due to drivetrain losses including but not limited to the transmission, rearend gears, bearing, the wheels themselves turning, etc. …Use the Drag Performance Calculator to calculate the theoretical 1/8 Mile ET, 1/4 Mile ET, 1/4 Mile Top End Speed, and Ideal 1/4 Mile Gear Ratio and the 0-60 MPH Time Calculator to calculate the theoretical 0-60 Time for a given application.
