Frequently Asked Questions
What is the ET method?
The ET (Elapsed Time) method uses your 1/4 mile time and vehicle weight to estimate horsepower. It was developed by drag racers and is surprisingly accurate for consistent runs.
WHP vs BHP vs crank HP?
WHP (wheel HP) is measured at the wheels on a dyno. BHP (brake HP) / crank HP is measured at the engine. The difference (12-18%) is drivetrain loss.
