Moroso Power-Speed Calculator

Using information such as tire size, gear ratios, horsepower, and displacement, this handy slide tool works out the relationship between:

E.T. and M.P.H. - Calculate elapsed time and mile per hour performance
Power to weight ratios - Determine vehicle power-to-weight characteristics
Tire diameter to speed and gear ratio - Work out gear ratios based on tire size
Engine displacement to compression ratio - Calculate engine specifications
Horsepower measurements - Measured at flywheel with ratings calculated for rear wheel horsepower

This calculator is like having a dyno in your back pocket, giving you an idea of what kind of elapsed time your car will run at the drag strip. The tool provides essential calculations for performance tuning and racing applications.
