UsinG THe HOT ROD CALC
note: The
Hot Rod Calc’s built-in Horsepower correction calculations are
based on formulas designed for naturally aspirated gasoline burning engines.
The Hod Rod Calc
helps you get the most out of your bracket racing
efforts by assisting you at the dragstrip in two very critical ways:
• Calculates the Air Density Index, based on your current local
measured weather inputs, to assist you with changing your
carburetor jet settings.
• Calculates a Horsepower correction factor, based on your
current local measured weather and/or track Elevation inputs,
to assist you with predicting changes in your engine’s perfor-
mance enabling better ET and speed predictions.
To further understand the Hot Rod Calc’s outputs and how to use the
calculator, please get familiar with the following technical and weather
related terms used throughout this section of the user’s guide.
iMPORTAnT: All examples are based on the default US units
mode, displaying entries and calculations in US units. Also note
that if an attempt is made to find a solution (using the motor,
performance or environmental functions) without having stored
the minimum required values, the calculation will not be per-
formed. instead, the currently stored value for the selected
function will be displayed (Tire Ratio displays nOne). See
Key
definitions section on page 4 for function requirements.
