A Computer Program designed for the motor sports enthusiast. Performance software that does the math for YOU. Handy Car Formulas for high performance math that will help you to analyze your (Street / Drag Racing, Circle Track, Oval Track, Road Racing, Off-Road) Car / Motorcycle / Kart / Engine and chassis needs, and improve performance. American or Metric Input (This is some what Limited). The menus are straightforward and "fill-in-the-blanks" data entry will get your answer. The most important thing to remember is that the more accurate your input to the program, the more accurate the answer will be. Although some examples may show only one or two decimal places the program will accept however many you key in, but any more then seven will not hold accuracy. Calculates engine displacement, Bore Stroke ratio, Rod Stroke ratio, Piston Speed, compression ratio, air and fuel flow, rear end gear ratio, shift RPM, 1/4 mile et and MPH, 60 foot MPH and G's, a change in Horsepower from a change in weather, or altitude, or adding blower pressure, Carburetor size in CFM, Carburetor size in CFM for blown engine, Blower Drive Ratio and RPM, Pressure Ratio, Intercooler Efficiency, Intercooler Density Ratio, Compressed Air Temperature, Blower Density Ratio, Compressor Inlet Flow in CFM, Drive Wheel Torque, Aerodynamic drag / HP Loss, Acceleration and Top Speed Prediction, Horse power Prediction from MPH's and Times, rollout distance, tire growth, trans power loss, shift rpm, shift time, % rear end power loss, % converter slippage, coefficient of drag (CD), launch rpm, Horse power Prediction from RPM's and Times, Est.
