Weather Wiz v1.1 for Windows 98/Me/XP/2000/NT/Vista/Win 7
Computer Program to make Weather Calculations which affect Engine, Carburetor Fuel Metering and Vehicle Performance for Drag Racing, Circle Track Racing, Road Racing, Dyno Tuning, and Street Tuning
Our new Weather Wiz lets you easily make all those weather related calculations like Density Altitude, Relative Air Density, Dyno Correction Factor and more. It lets you specify the inputs you want to use for entering barometric pressure, humidity and air temperature. It also "talks" to our Weather Station for instant updates of critical data.
Unlike most programs, you don't have to use the same types of inputs for the comparison. For example, your baseline condition may use a barometer instrument, and your comparison may use an altimeter. Or your baseline condition may use wet and dry bulb temperature for humidity, but a dew point reading for your comparison conditions.
It also lets you specify the air temperature at the engine (which is the critical temperature) different than where the humidity was measured. For example, your relative humidity instrument (or wet and dry bulb instrument) may be in your trailer or dyno control room. However, the air going to the engine may be considerably warmer. This definitely has an effect on engine performance and carb jetting.
