This application computes water balance outputs from user inputs.

The program also allows you to choose the number of decimal places and gives you the option to display the results in scientific notation.

Overdrive Automotive Tools 2.1 features 21 entirely freeware calculators in 4 categories related to automotive tuning and design:

• Fluid dynamics: Rectangular wing downforce; Aerodynamic top speed; Compressible duct flow; Incompressible venturi flow
• Engine and Transmission: Tuned intake manifold sizing; Required engine airflow; Compression ratio; Fuel injector sizing; RPM/Gear ratio/speed; DIN correction factors; Optimum shifting points
• Suspension and Chassis: Coil spring rate; Optimum shock absorber; Tire diameter; Chassis frequencies; Braking force; Maximum traction-limited acceleration;
• Performance: Power from mile timeslip; Torque from mile MPH; 0-60 and mile time correlation; Environmental correction factors for mile ET;

The program features basic calculations such as exact tire diameter and engine compression ratio, while innovating with advanced modules like tuned intake manifold sizing or braking system design. This will give easy access to the formulas and numbers the race car designer, drag/circle track racer or weekend hobbyist needs.
