Calculations

Speed-Wiz has calculations in the areas of general, conditions, fuels, engine calculations, engine simulation, fuel injection, turbochargers, chassis, aerodynamics, electrical, suspension, steering, brakes, tires, performance, reference, costs, maintenance, and race strategy. It calculates hundreds of different values. It also has graphs for the same areas. In addion are unit conversions, performance optimizations, a lap timer, and some fun stuff too.
